The following figures are similar, find the value of x

Answers

Answer 1

Answer:

Answer:

x=143

Step-by-step explanation:

scale factor (if that is the correct term) is 13. you find that by matching sides to side. this means that 91/7=13, therefore you know that 4*13 is 52 and 11*13 is 143

Answer 2

Answer: The answer is x =143 I’m pretty sure

(G1) The distance from Flagstaff Arizona toTucson Arizona is 260 miles. Express this
distance in meters.
A. 418,418 meters
B. 419,000 meters
C. 126,200 meters
D. 260,000 meters

Answers

Answer:

A. 418, 418

Step-by-step explanation:

The formula to convert miles to meters is the following:

1 = 1,609.34

so for every 1 mile, you have 1,609.34 meters

so you take your distance in miles and multiply it by 1,609.34

d= 260 x 1,609.34

d = 418, 428.4

The board of a large company is made up of 7 women and 9 men. 6 of them will go as a delegation to a national conference. a) How many delegations are possible?

b) How many of these delegations have all men?

c) How many of these delegations have at least one woman?

Answers

Answer:

a) 5765760

b) 60480

c) 5705280

Step-by-step explanation:

Assuming that order is not important:

Number of women = 7

Number of men = 9

Members of the delegation = 6

a) How many delegations are possible?

$n=(16!)/((16-6)!)=16*15*14*13*12*11\n n= 5765760$

b) How many of these delegations have all men?

$n_(men) = (9!)/((9-6)!)=9*8*7*6*5*4 \nn_(men) = 60480$

c) How many of these delegations have at least one woman?

$n_(women >0)=n-n_(men)\nn_(women >0) =5765760-60480\nn_(women >0) =5705280$

Answers

Answer:

V = 23,900(0.936)(0.936)(0.936)(0.936)

Step-by-step explanation:

AI-generated answer

The equation that represents the value of the car after 4 years is:

V = 23,900(0.936)(0.936)(0.936)(0.936)

Let's break it down step by step:

1. The initial value of the car is $23,900.

2. The car depreciates at a rate of 6.4% per year. This means that after each year, the car's value decreases by 6.4%.

3. To find the value of the car after 1 year, we multiply the initial value by 0.936 (100% - 6.4% = 93.6%).

4. To find the value of the car after 2 years, we multiply the value after 1 year by 0.936 again.

5. We repeat this process for 4 years, multiplying the value after each year by 0.936.

Therefore, the equation V = 23,900(0.936)(0.936)(0.936)(0.936) represents the value of the car after 4 years, taking into account the 6.4% annual depreciation rate.

Note: The other options given in the multiple-choice answers do not accurately represent the correct equation for calculating the value of the car after 4 years.

A hypothesis will be used to test that a population mean equals 7 against the alternative that the population mean does not equal 7 with known variance σ. What are the critical values for the test statistic Upper Z Subscript 0 for the significance level of 0.04? Round your answer to two decimal places (e.g. 98.76).

Answers

The upper critical value z₀ of the hypothesis is 2.05.

How to explain the hypothesis?

From the information given, it can be noted that this is a two-sided test. In this case, the critical values are the values of z that determine the boundaries of whether one should reject the null hypothesis or shouldn't.

Since the significance level is 0.04, it simply implies that there is a p-value of 0.02. Then, the next thing is to check the normal distribution table, and this corresponds to the z value of 2.05.

In conclusion, the correct option is 2.05.

Answer:

The upper critical value z₀ is 2.05.

Step-by-step explanation:

For a two-sided test like this (the mean can be significantlt greater or smaller than 7 to reject the null hypothesis), the critical values are the values of z that determine the boundaries of rejecting or not the null hypothesis.

If the significance level is 0.04, it means that there is a P-value of 0.02 for z larger than the upper critical value z₀.

$P(z>z_0)=\alpha /2= 0.02$

If we look up in a normal distribution table, the z value that corresponds to this probability is z=2.05.
