The Answer is: C.120

Answer:

∠ RST = 120°

Step-by-step explanation:

∠ RST = ∠ RSU + ∠ UST , substitute values

6x + 12 = 78 + 3x - 12

6x + 12 = 3x + 66 ( subtract 3x from both sides )

3x + 12 = 66 ( subtract 12 from both sides )

3x = 54 ( divide both sides by 3 )

x = 18

Thus

∠ RST = 6x + 12 = 6(18) + 12 = 108 + 12 = 120°

The mean, or average, is equal to the sum of all the miles divided by the number of terms you added together. We have 4 terms that will be added, but are missing one term. We will solve for the missing term by setting up an equation for the average and solving for x, the number of miles you must run on Thursday.

3 = (2 + 3 + 4 + x) / 4

12 = 2 + 3 + 4 + x

12 = 9 + x

x = 3 miles

Answer:

A) x+5=x+3

B) x+5=5+x

Step-by-step explanation:

A) If an equation has no solutions then when it is algebraically solved it will be an untrue statement.

For example, x+5=x+3. To solve subtract x from both sides. This becomes 5=3, which is not a true statement. Therefore, there are no solutions.

B) If an equation has infinite solutions then when it is algebraically solved it will be a statement that is always true.

For example, x+5=5+x. To solve first subtract x from both sides. This equals 5=5, which is always true. Therefore, there are infinite solutions.

Area of semicircle is (πr²)/2 and perimeter is  (πr) + 2r

The area and perimeter of a semicircle can be calculated using the formulas for the area and circumference of a full circle, and then dividing by 2.

The formula for the area of a full circle is A = πr², where r is the radius of the circle. So the area of a semicircle would be A = (πr²)/2.

The formula for the circumference of a full circle is C = 2πr, where r is the radius of the circle. The perimeter of a semicircle would be half of the circumference, plus the diameter (which is 2r). So the perimeter of a semicircle would be P = (πr) + 2r.

So, to find the area and perimeter of a semicircle, you would need to know the radius of the semicircle, and then plug it into the formulas above.

For example, if the radius of the semicircle is 4, the area would be A = (π(4²))/2 = 8π, and the perimeter would be P = (π(4)) + (2(4)) = 4π + 8.

Bartlett's test is often run in conjunction with ANOVA to test for equal variances among treatment groups. The correct answer is option (a).

In ANOVA (Analysis of Variance), we compare the means of multiple groups to determine if there are statistically significant differences among them. However, it is important to also assess the assumption of equal variances across those groups. Bartlett's test is a statistical test used to examine the equality of variances among treatment groups.

The test assesses whether the observed variances of the groups significantly differ from each other. If the p-value from Bartlett's test is greater than the chosen significance level (usually 0.05), it suggests that the variances are not significantly different, supporting the assumption of equal variances among treatment groups. On the other hand, if the p-value is below the significance level, it indicates unequal variances, which may impact the validity of the ANOVA results.

Therefore, the correct answer is (a) equal variances among treatment groups. Bartlett's test helps to determine if the assumption of equal variances in ANOVA is met or violated.

The hypothesis in a hypothesis test is an alternative hypothesis a statement about a parameter.

An alternative hypothesis in a hypothesis test is a statement about a parameter, not a statistic. The null hypothesis is typically a statement about a parameter that assumes there is no significant difference or relationship, while the alternative hypothesis is a statement that contradicts the null hypothesis and suggests there is a significant difference or relationship.

The alternative hypothesis can take one of three forms: it can be a one-tailed hypothesis (either greater than or less than the null hypothesis), or a two-tailed hypothesis (not equal to the null hypothesis). In all cases, the alternative hypothesis is a statement about the population parameter, which is typically denoted by a Greek letter such as μ (mean) or σ (standard deviation).

Therefore, the alternative hypothesis is a statement about the parameter being tested.

Answer:

your correct answer is y=-1/5-3

Step-by-step explanation:

The linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

The slope is given as:

m = -1/5

The y-intercept is given as:

c = -3

A linear equation in slope intercept form is represented as:

y = mx + c

So, we have:

y = -1/5x - 3

The equation in point slope form is calculated as follows:

y = -1/5x - 3

Add 3 to both sides

y + 3 = -1/5x

Express -1/5x as -1/5(x)

y + 3 = -1/5(x)

Subtract 0 from x

y + 3 = -1/5(x - 0)

Hence, the linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

There are 5 blue markers in the bag. Let's start by using the formula for calculating the probability of two independent events occurring together

P(A and B) = P(A) * P(B), where P(A) is the probability of event A occurring and P(B) is the probability of event B occurring. We know that the probability of selecting a yellow marker on the first draw is 7/ (7+n), since there are 7 yellow markers and a total of (7+n) markers. Since we are drawing without replacement, there will be n-1 blue markers left for the second draw out of a total of (6+n) markers. Therefore, the probability of drawing a second yellow marker is 6 / (6+n-1) or 6 / (5+n).

Multiplying these two probabilities gives us the probability of drawing two yellow markers:  (7 / (7+n)) * (6 / (5+n)) = 3/13

Simplifying this equation, we get:

42 = 3(35 + n)

Solving for n, we get:

n = 5

Therefore, there are 5 blue markers in the bag.

The sum of the series [infinity] an n = 1, whose partial sums are given by sn = 5 - 4(0.7)^n, can be calculated using the formula for the sum of a geometric series.

The common ratio of the series is 0.7, and the first term can be found by substituting n = 1 into the given formula.

The formula for the sum of an infinite geometric series is given by S = a / (1 - r), where 'a' is the first term of the series and 'r' is the common ratio. In this case, the partial sums are given by sn = 5 - 4(0.7)^n.

To find the first term 'a', we substitute n = 1 into the formula for sn:

s1 = 5 - 4(0.7)^1 = 5 - 4(0.7) = 5 - 2.8 = 2.2.

Therefore, the first term of the series is a = 2.2, and the common ratio is r = 0.7.

Using the formula for the sum of a geometric series, we can now calculate the sum of the series:

S = a / (1 - r) = 2.2 / (1 - 0.7) = 2.2 / 0.3 = 7.33.

Hence, the sum of the series [infinity] an n = 1, with partial sums given by sn = 5 - 4(0.7)^n, is equal to 7.33.
