Step-by-step explanation:

Hey There!

for this problem we are finding the coordinates of a translated figure

To do so we subtract the pre-image x values by 5 and subtract the y values by 3

for A

1-5=-4

1-3=-2

so the coordinates of A' would be (-4,-2)

for B

4-5=-1

2-3=-1

so the coordinates of B' would be (-1,-1)

for C

3-5=-2

5-3=2

so the coordinates of C' would be (-2,2)

answer choice b matches our answers there for B is the answer

Answer:

15 °C

Step-by-step explanation:

°C = (°F - 32) * (5/9)

Given that the initial temperature was 77 °F and it dropped by 10 °C, we can calculate the final temperature.

Initial temperature: 77 °F

Converting to Celsius:

°C = (77 - 32) * (5/9)

°C ≈ 25

The temperature dropped by 10 °C, so the final temperature is:

Final temperature = Initial temperature - Temperature drop

Final temperature ≈ 25 - 10 = 15 °C

Therefore, the temperature after the storm was approximately 15 °C.

Answer:

1.\(\frac{24}{7}\)
2.\(\frac{21}{6}\)

Step-by-step explanation:

Given the following questions:

\(3\frac{3}{7} \\3\frac{5}{6}\)

To convert mixed numbers into improper fractions we need to multiply the denominators by the whole numbers, and then add that answer to the numerator while of course keeping the denominator the same.

Question one:

\(3\frac{3}{7} \\3\frac{3}{7} =7\times3=21+3=24=\frac{24}{7} \\=\frac{24}{7}\)

Question two:

\(3\frac{5}{6} \\3\frac{5}{6}=6\times3=18+3=21=\frac{21}{6} \\=\frac{21}{6}\)

Your answers are "24/7, and 21/6."

Hope this helps.

Answer:

The 95% confidence interval is \(1003 < \mu <1023\)

b

Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States

Step-by-step explanation:

From the question we are told that

   The population mean is  \(\mu = 1000\)

   The sample size is  \(n = 453\)

   The sample mean is  \(\= x = 1013\)

    The standard deviation is \(s = 108\)

Given that the confidence level is  95% then the level of significance is mathematically represented as

            \(\alpha = 100 - 95\)

=>         \(\alpha = 5\%\)

=>          \(\alpha = 0.05\)

The critical value  for \(\frac{\alpha }{2}\) obtained from the normal distribution table is          

          \(Z_{\frac{\alpha }{2} } = 1.96\)

Generally the margin of error is mathematically represented as

         \(E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }\)

=>     \(E = 1.96 * \frac{108}{\sqrt{453} }\)

=>      \(E = 9.946\)

Generally the 95% confidence interval is mathematically represented as

           \(\= x - E < \mu < \= x + E\)

=>         \(1013 - 9.946 < \mu < 1013 + 9.946\)

=>         \(1003 < \mu <1023\)

Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States

Answer:

the answer is 240 degrees

To find z^4, we can raise z to the fourth power, since z^4 = (z)^4. Using the polar form of z, we have:

z = 2cis(60°)

We can convert this to rectangular form using the following formulas:

x = r cosθ

y = r sinθ

where r is the magnitude of z, and θ is the angle in radians.

r = 2

θ = 60° = π/3 radians

x = 2 cos(π/3) = 1

y = 2 sin(π/3) = √3

Therefore, z = 1 + √3i

Now, we can raise z to the fourth power:

z^4 = (1 + √3i)^4

Using the binomial expansion formula, we can expand this expression:

z^4 = 1 + 4(√3i) + 6(-1) + 4(-√3i) + 1

Simplifying, we get:

z^4 = -8 + 8√3i

Therefore, z^4 in rectangular form is -8 + 8√3i.

The formula for the braking distance S (t) after t seconds will be t = = ✓22D / 9

From the information, the braking distance D (v) (in meters) for a certain car moving at velocity v (in meters/second) is given by D (v) = v²/22.

It should be noted that the car's velocity B (t) (in meters/second) t seconds after starting is given by B (t) = 3t.

The formula for the braking distance S (t) (in meters) after t seconds will be:

D = v² / 22

Replace v by 3t

D = (3t)² / 22

D = 9t² / 22

Cross multiply

22D = 9t²

t² = 22D / 9

t = ✓22D / 9

The required coordinate of B' is B' = (4, -5), across the y-axis after reflection. Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them.

here,
Given that a point B (-4, -5) is reflected across the y-axis, the Coordinate of image B' is to be determined.

Since the coordinate is reflected across the y-axis,
The equation of trasformation is given as,
(x , y) ⇒ (-x , y)

So, the image of B,

Answer:

1. The sum of the residuals is always close to zero.

2.The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.

3. In the equation of the least-squares regression line, y hat is a predicted value when x is known

Step-by-step explanation:

The least square regression line is a line that makes distance from data points to the regression line to be as minimal as possible. This line is a best fit for the data points. Let's say we have a collection of numbers and a scatter plot, this line is a line that exists and best fits the data.

Therefore, the least square regression line minimizes sum of squared error to be close to zero. R² measures the extent to which variations in the value of y is explained by the regression line. In the equation of this line, y hat is a predicted value when x is known.

The least square regression line minimizes the sum of squared error such that the sum of the residual is zero or very close to 0. Hence, the true statements from the options given are :

The least square regression Line is used to create a Linear model in the form y = bx + c

The Coefficient of determination R² gives the proportion of the variation explained by the regression line.

The predicted value of y is obtained using the model of the Least Square Regression Line for a given value of x.

Outlier values often affects the performance and accuracy of the Least Square Regression Line.

There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.

To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.

Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:

Total combinations = Number of color options × Number of wheel size options

Total combinations = 4 colors × 2 wheel sizes

Total combinations = 8

Answer:

9/25 or 36%

Step-by-step explanation:

The probability of selecting the fair coin is 1/2, and the probability of getting heads with the fair coin is 1/2.

P(fair) = 1/2, P(heads | fair) = 1/2

The probability of selecting the unfair coin is 1/2, and the probability of getting heads with the unfair coin is 2/3.

P(unfair) = 1/2, P(heads | unfair) = 2/3

P(fair and 2 heads) = 1/2 (1/2)²

P(fair and 2 heads) = 1/8

P(2 heads) = 1/2 (1/2)² + 1/2 (2/3)²

P(2 heads) = 1/8 + 2/9

P(2 heads) = 25/72

Therefore, the probability that you selected the fair coin, given that you flipped 2 heads, is:

P(fair | 2 heads) = (1/8) / (25/72)

P(fair | 2 heads) = (1/8) (72/25)

P(fair | 2 heads) = 9/25

While an absolute value may be any number, the output from an absolute value expression is always greater than or equal to zero

The absolute value | x | of a real number x is defined as the non-negative value of x without regard to its sign. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero along real number line.

The absolute value of any number is seen to be always greater than or equal to zero. Both a number and its opposite are the same distance from zero on the number line. Since they have the same distance from zero, they have the same absolute value.

The attached figure represents the image of A'B'C'D after dilation

The points are given as:

B = (-1,1)

C = (0,-5)

D = (-6,-5)

The scale factor and the center of dilation are given as:

k = -2

P (a,b) = (-3,-2)

The rule of this dilation is:

(x,y) = (k(x - a) + a, k(y - b) + b)

This gives

(x,y) = (-2(x + 3) - 3, -2(y + 2) - 2)

So, we have:

A' = (-2(-4 + 3) - 3, -2(1 + 2) - 2)

A' = (-1, -8)

B' = (-2(-1 + 3) - 3, -2(1 + 2) - 2)

B' = (-7, -8)

C' = (-2(0 + 3) - 3, -2(-5 + 2) - 2)

C' = (-9, 4)
