Answer:  The correct answer is x = 19 / 5

Step-by-step explanation:

Solve the equation

5x + 3 = 22

Subtract 3 from both sides

5x + 3 − 3 = 22 − 3

5x = 19

Divide both sides by 5

5x/5 = 19/5

x = 19 / 5

Answer:

$620 every year

Step-by-step explanation:

Since the question didn't specify how long she would have to save for, let's just assume that it's one year. There are 52 weeks in a year which is $520, and on her birthday she would have an extra $100, so every year she saves $620 in total.

Answer:

8.

Step-by-step explanation:

(8+4)=12. 12 x 1/2 = 6.

The mean score for the test Phyllis scored 84, exactly one standard deviation above the mean is  78.

One of the statistics used in the generalised Cochran-Mantel-Haenszel tests is the mean score statistic. When the answer levels (columns) are assessed using an ordinal scale, it is applicable.

The chi-square distribution with (R-1) degrees of freedom, where R is the number of treatment groups, serves as the asymptotic distribution of the mean score statistic if the two variables are independent of one another in all strata (rows).

If the mean scores of the response differ between the treatment groups in at least one stratum, the mean score statistic tends to have larger values. The term "nonparametric ANOVA statistic" also applies to this statistic.

x = 84

\(\sigma=6\)

since, x is 1 standard deviation above mean so,

\(z=\frac{x-\mu}{\sigma}\)

\(1=\frac{84-\mu}{6}\\ \\\)

\(\mu\) = 84-6

\(\mu\) =78.

therefore, mean = 78.

BC ≈ 8.9 units

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos36° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{BC}{AB}\) = \(\frac{BC}{11}\) ( multiply both sides by 11 )

11 × cos36° = BC , then

Step-by-step explanation:

For a one-tailed test with a 0.05 level of significance, the critical z statistic is 1.645, but the critical t statistic is 1.96. The statement is false.

The statement is incorrect. For a one-tailed test with a 0.05 level of significance, the critical z statistic is indeed 1.645. However, the critical t statistic value depends on the degrees of freedom (df), which is not provided in the statement. The 1.96 value mentioned is actually the critical z statistic for a two-tailed test with a 0.05 level of significance.

The recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5

The function is given as:

h(n) = 41- 5n

Calculate h(1) and h(2)

h(1) = 41- 5(1)

h(1) = 36

h(2) = 41- 5(2)

h(2) = 31

Calculate the difference between h(1) and h(2)

d = 31 - 36

d = -5

This means that:

h(1) = 36 and h(n) = h(n -1) - 5

Hence, the recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5

Given the joint probability density function (PDF) of two continuous random variables X and Y, we need to find their marginal PDFs, determine if X and Y are independent, find the conditional PDF of X given Y = y, and calculate the conditional expectation E(X|Y = y) for a specific range of y.

a) To find the marginal PDF of X, integrate the joint PDF with respect to Y over the entire range of Y: fx(x) = ∫(0 to 1) 6xy dy. Evaluate the integral and simplify to obtain the marginal PDF of X.

b) To find the marginal PDF of Y, integrate the joint PDF with respect to X over the entire range of X: fy(y) = ∫(0 to ∞) 6xy dx. Evaluate the integral and simplify to obtain the marginal PDF of Y.

c) To determine if X and Y are independent, check if the joint PDF can be factored into the product of the marginal PDFs: fx.y(x, y) = fx(x) * fy(y). If they can be factored, X and Y are independent; otherwise, they are dependent.

d) To find the conditional PDF of X given Y = y, use the conditional probability formula: fxy(x|y) = fx.y(x, y) / fy(y). Substitute the joint PDF and the marginal PDF of Y into the formula to obtain the conditional PDF.

e) To calculate the conditional expectation E(X|Y = y), integrate the product of X and the conditional PDF of X given Y = y over the range of X: E(X|Y = y) = ∫(0 to ∞) x * fxy(x|y) dx. Evaluate the integral to find the conditional expectation.

Answer:

he has 10 type of each coin

Step-by-step explanation:

Total number of cents in possession is calculated as;

= 25 + 10 + 5

= 40 cent

Total amount in possession = $4

                                               = 400 cent

Since he has equal number of each cent, let this equal number be "y";

40cent (y) = 400cent

40y = 400

divide both sides by 40

\(\frac{40y}{40} = \frac{400}{40} \\\\y = 10\)

Therefore, he has 10 type of each coin

The points (2, 2), (4, - 2), (- 6, - 2), (- 2, 4) are examples of ordered pairs on the coordinate plane.

Coordinate planes are generated by the intersection of two orthogonal axes, a "horizontal" (x-axis) and a "vertical" (y-axis), at a point known as origin. These axes creates four regions known as quadrants, which are introduced in the image attached below.

All the ordered pairs are points of the form (x, y), where x and y represent the orthogonal positions of the point with respect to the origin. Now we proceed to present four examples of ordered pairs, each located in each quadrant: (2, 2), (4, - 2), (- 6, - 2), (- 2, 4).

Answer:

Slope M=6

Step-by-step explanation:

Answer:

D.) The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.

Step-by-step explanation:

So the first thing we have to do is look at the information given, we know that the shape on the left is translated into the shape on the right. When a shape is "translated" it simply means that the shape doesn't change in size or rotation it only glides or moves. So the shape on the right is the former shape and the shape on the left is the pre-image.

Knowing that the left shape is the pre-image goes ahead and eliminates answer choices B & C as both answers mention that the right side is the image before the transformation which because of what was previously mentioned, is incorrect.

This leaves only answer choices A and D. Finally we can narrow down the final answer by knowing that the apostrophe " ' " or prime should be placed after each letter not just at the end of letters. For example A'B'C'D' not ABCD'. If we apply this rule to the last to answer choices we can see that D is the correct answer.

Step-by-step explanation:

Given the function h(x) = x² - 7x - 8. The extremum of the function is the minimum one and its value is h(x) = -32.5

The relation between symmetry of the graph and the extremum point is:

Suppose x = p is the line equation of the graph's symmetry, then f(p) is the extremum value.

The given function is:

h(x) = x² - 7x - 8

Find the x-intercepts:

h(x) = 0

x² - 7x - 8 = 0

(x + 1) (x - 8) = 0

x = -1 or x = 8

The symmetry lies in the middle of x-intercepts. Hence, the symmetry occurs at:

x = (-1 + 8) / 2

x = 3.5

The extremum point is:

h(3.5) = 3.5² - 7 x 3.5 - 8 = -32.5

Since the quadratic term x²  has a positive coefficient, the graph is open downward, hence the extremum point is the minimum one.

Answer:

The first swing is 64m

Step-by-step explanation:

The complete question asks for how long the first swing is.

The monkey is swinging from the tree with each swing being along an arc, where each arc is 75% of the previous arc. Also, given that its first four swings is 175cm, we can denote her first swing as y.

This means the second swing would be = 0.75y

The third would be = 0.75(0.75y) = 0.5625y

The fourth would be = 0.75(0.5625y) = 0.421875y

Since the total is 175, we have

y + 0.75y + 0.5625y + 0.421875y = 175

2.734375y = 175

y = 175/2.734375

y = 64m

Answer:

8 Hours

Step-by-step explanation:

We know she travels 220 miles in 5 hours, so lets create an equation with a ratio which finds the miles she drives in a single hour, multiply that by x, and then set it equal to 352.

\(\frac{220}{5}x=352\)

Multiply both sides by 5

\(220x=1760\)

Divide both sides by 220

\(x=8\)

Therefore it would take 8 hours.

8 Hours long would it take to travel 352 miles,

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other words, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined. The SI unit system is most frequently used to express speed units. In that system, since distance is measured in metres and time is measured in seconds, speed is expressed in metres per second, or m/s. Three components make up the speed formula: distance, time, and speed.

We know she travels 220 miles in 5 hours, so lets create an equation with a ratio which finds the miles she drives in a single hour, multiply that by x, and then set it equal to 352.

Multiply both sides by 5

Divide both sides by 220

Hence, it would take 8 hours.
