The graph of the line y = 2x - 2 intersects the y-axis at the point (0, -2).

Given that we have the following equation

y = 2x - 2

The equation of a straight line in the standard form is y = mx + c, where m is the slope of the line, and c is the y-intercept. The y-intercept is the point at which the line intersects the y-axis.

The equation of the line is y = 2x - 2. To find where the line intersects the y-axis, we need to set x = 0 and solve for y.

So, when x = 0, we get:

y = 2(0) - 2

y = -2

Therefore, the line intersects the y-axis at the point (0, -2).

The expression that can be used to find the value of y when x is 11 is y = (198/5) in fraction form.

If y varies directly as x, it means that y and x are proportional to each other. We can write this relationship as y = kx, where k is the constant of variation.

To find the value of y when x is 11, we need to determine the value of k. We can use the given information that when x is 5, y is 18.

Substituting these values into the equation, we get:

18 = k * 5

To find the value of k, divide both sides of the equation by 5:

k = 18/5

Now that we have the value of k, we can use the equation y = kx to find the value of y when x is 11.

Substituting x = 11 and k = 18/5 into the equation, we get:

y = (18/5) * 11

Simplifying the expression, we have:

y = (198/5)

Therefore, the expression that can be used to find the value of y when x is 11 is y = (198/5) in fraction form.

Answer:

77/134 or 0.5746

Step-by-step explanation:

The approximate relative frequency is "the number of times that the event occurs during experimental trials, divided by the total number of trials conducted."

So we need to identify the number of times the event occured, the amount of times children chose sweet snacks, and the total number of trials conducted. So since the question wants the approximate relative frequency by column, we use the number 134 for the total number, and 77 for the number of times the event occurred. We then divide 77 by 134, which looks like this: 77/134. In decimal form, this equals 0.5746. It can't be simplified anymore in fraction form, so 77/135 would be another way to answer.

Rounding up the result to the nearest integer, we get the minimum sample size required as 271.  Correct option is D.

To estimate the mean SAT score for a population of students with a 90% confidence interval, we need to determine the minimum sample size required to achieve a maximum margin of error of 10, assuming that the population standard deviation is 100.

The formula to calculate the sample size required is:

n = [(zα/2 * σ) / E]^2

Where:

zα/2 is the z-value for the desired confidence level (90% confidence interval in this case) = 1.645

σ is the population standard deviation = 100

E is the maximum margin of error = 10

Substituting the values in the formula, we get:

n = [(1.645 * 100) / 10]^2 = 270.7225

Therefore, option (d) is the correct answer.

In summary, to estimate the mean SAT score for a population of students with a 90% confidence interval and a maximum margin of error of 10, we need a minimum sample size of approximately 271 students, assuming that the population standard deviation is 100.

Answer:

Step completed incorrectly:  2

Correct Answer: y = -4x + 22

Step-by-step explanation:

The graph is a straight line through points M(4, -1) and N(8, 0).  Point Q is located at (6, -2).

To calculate the slope of the line, substitute the points into the slope formula:

\(\textsf{Slope $(m)$}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-(-1)}{8-4}=\dfrac{1}{4}\)

Therefore, the slope of MN is 1/4, so step 1 of Francisco's calculations is correct.

If two lines are perpendicular to each other, the slopes of these lines are negative reciprocals. The negative reciprocal of a number is its negative inverse.

The negative reciprocal of 1/4 is -4.

Therefore, the slope of the perpendicular line is -4.

So Francisco has made an error in his calculation in step 2 by not making the perpendicular slope negative.

Corrected work

\(\textsf{Step 1:} \quad \sf slope\;of\;MN:\; \dfrac{1}{4}\)

\(\textsf{Step 2:} \quad \sf slope\;of\;the\;line\;perpendicular:\; -4\)

\(\begin{aligned}\textsf{Step 3:} \quad y-y_1&=m(x-x_1)\;\; \sf Q(6,-2)\\y-(-2)&=-4(x-6)\end{aligned}\)

\(\textsf{Step 4:} \quad y+2=-4x+24\)

\(\textsf{Step 5:} \quad y+2-2=-4x+24-2\)

\(\textsf{Step 6:} \quad y=-4x+22\)

Therefore, step 2 has been completed incorrectly.

The correct answer is y = -4x + 22.

Answer:

the probability that Eric gets fewer than 5 questions correct is approximately 0.857, or 85.7%.

Step-by-step explanation:

Let X be the number of questions Eric gets correct. Since there are 7 questions and each has 4 choices, the probability of guessing any one question correctly is 1/4, and the probability of guessing any one question incorrectly is 3/4. Since Eric is guessing on every question, we can model X as a binomial random variable with n = 7 and p = 1/4.

To find the probability that Eric gets fewer than 5 questions correct, we need to calculate:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

Using the binomial probability mass function, we get:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where (n choose k) is the binomial coefficient, which gives the number of ways to choose k items from a set of n items.

Plugging in n = 7 and p = 1/4, we get:

P(X = k) = (7 choose k) * (1/4)^k * (3/4)^(7 - k)

Therefore, we have:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

= (7 choose 0) * (1/4)^0 * (3/4)^7 + (7 choose 1) * (1/4)^1 * (3/4)^6

+ (7 choose 2) * (1/4)^2 * (3/4)^5 + (7 choose 3) * (1/4)^3 * (3/4)^4

+ (7 choose 4) * (1/4)^4 * (3/4)^3

≈ 0.857

Therefore, the probability that Eric gets fewer than 5 questions correct is approximately 0.857, or 85.7%.

There is no significant difference between the mean scores of Education and Nursing students in mathematics.

Null hypothesis (H₀): There is no significant difference between the mean scores of Education and Nursing students in mathematics.

Alternative hypothesis (H₁): There is a significant difference between the mean scores of Education and Nursing students in mathematics.

We will use significance level (α) of 0.01.

Given:

Sample mean for Education students (x₁) = 88.50

Sample mean for Nursing students (x₂) = 90.25

Standard deviation for the Education student sample (s₁) = 7.5

Standard deviation for the Nursing student sample (s₂) = 8.2

Sample size for Education students (n₁) = 25

Sample size for Nursing students (n₂) = 29

The t-test statistic for two independent samples is:

t = (x1₁ - x2) / sqrt((s₁² / n₁) + (s₂² / n₂))

t = (88.50 - 90.25) / sqrt((7.5² / 25) + (8.2² / 29))

t ≈ -0.8187

In this case, df = 24.

The critical value for α = 0.01 and df = 24 is approximately ±2.797.

Since |-0.8187| < 2.797, the absolute value of the t-test statistic is smaller than the critical value.

Therefore, we fail to reject the null hypothesis.

The probability P(X < 4) is approximately 0.2734 when X has a binomial distribution with n = 7 and p = 0.5.

When X has a binomial distribution with n = 7 and p = 0.5, we can use the cumulative distribution function (CDF) or the formula for the probability mass function (PMF) of the binomial distribution to determine the probability P(X 4) by adding the probabilities for X = 0, 1, 2, and 3.

Binomial CDF usage:

P(X 4) = P(X 3) = binom.cdf (3, n = 7, p = 0.5) 0.2734

Binomial PMF usage:

P(X 4) = P(X = 0), P(X = 1), P(X = 2), and P(X = 3) = binom.pmf(0, n=7, p=0.5), binom.pmf(1, n=7, p=0.5), binom.pmf(2, n=7, p=0.5), and binom.pmf(3, n=7, p=0.5), and binom.pmf(3, n=7, p=0.5) = 0.2734.

Since X has a binomial distribution with n = 7 and p = 0.5, the chance P(X 4) is roughly equal to 0.2734.

The probabilities that could complete the model and maintain a total sum of 1 are options B and E.

B: P(green) = 3/8, P(yellow) = 1/8

E: P(green) = 3/7, P(yellow) = 1/14

To determine the probabilities that could complete the model, we need to consider the sum of all probabilities. In a probability model, the sum of all probabilities should equal 1.

Given the probabilities P(red) = 2/7 and P(blue) = 3/14, let's calculate the sum:

P(red) + P(blue) = 2/7 + 3/14 = 4/14 + 3/14 = 7/14 = 1/2

Since the sum of P(red) and P(blue) is 1/2, we need to find the probabilities for P(green) and P(yellow) that, when added to 1/2, give a total sum of 1.

Looking at the answer key options:

A: P(green) = 2/7, P(yellow) = 2/7

B: P(green) = 3/8, P(yellow) = 1/8

C: P(green) = 1/4, P(yellow) = 1/4

D: P(green) = 5/21, P(yellow) = 11/21

E: P(green) = 3/7, P(yellow) = 1/14

Let's check the sums:

A: P(red) + P(blue) + P(green) + P(yellow) = 2/7 + 3/14 + 2/7 + 2/7 = 4/14 + 3/14 + 4/14 + 4/14 = 15/14 ≠ 1 (incorrect)

B: P(red) + P(blue) + P(green) + P(yellow) = 2/7 + 3/14 + 3/8 + 1/8 = 4/14 + 3/14 + 6/14 + 1/14 = 14/14 = 1 (correct)

C: P(red) + P(blue) + P(green) + P(yellow) = 2/7 + 3/14 + 1/4 + 1/4 = 4/14 + 3/14 + 7/14 + 7/14 = 21/14 ≠ 1 (incorrect)

D: P(red) + P(blue) + P(green) + P(yellow) = 2/7 + 3/14 + 5/21 + 11/21 = 6/14 + 3/14 + 10/14 + 11/14 = 30/14 ≠ 1 (incorrect)

E: P(red) + P(blue) + P(green) + P(yellow) = 2/7 + 3/14 + 3/7 + 1/14 = 4/14 + 3/14 + 6/14 + 1/14 = 14/14 = 1 (correct)

Based on the calculations, the probabilities that could complete the model and maintain a total sum of 1 are options B and E. So, the correct answers are:

B: P(green) = 3/8, P(yellow) = 1/8

E: P(green) = 3/7, P(yellow) = 1/14

Applying the tangent and the circle theorems, we have:

22. x ≈ 9.4;   23. Perimeter of triangle GHI = 168 units

24. m<NSR = 110°;    25. x = 10

22. Based on the tangent theorem, the triangle is a right triangle since the line is tangent to the radius of the circle. Therefore, based on the Pythagorean theorem, we have:

x = √[(7.4 + 4.6)² - 7.4²]

x ≈ 9.4

23. JH and HK are tangents, therefore they are equal. Thus:

7x + 4 = 13x - 20

7x - 13x = -4 - 20

-6x = -24

x = 4

Perimeter = GI + GJ + JH + HK + KI

GI = 52

HK = JH = 7x + 4 = 7(4) + 4 = 32

KI = 15

GJ = 52 - 15 = 37

Perimeter of triangle GHI = 52 + 37 + 32 + 32 + 15 = 168 units

24. Based on the angle of intersecting chords theorem, we have:

m<NSR = 1/2(170 + 50)

m<NSR = 110°

25. Based on the inscribed angle theorem, we have:

2(4x - 5) + 290 = 360

Solve for x:

8x - 10 + 290 = 360

8x = 360 - 280
