Answer: The required length of the longest side is 63 inches.

Step-by-step explanation: Given that the perimeter of the triangle shown is 162 inches.

We are to find the length of the longest side.

From the figure, we note that the lengths of the three sides of the triangle are 7x, 6x and 5x.

Since the perimeter of a triangle is equal to the sum of the lengths of the three sides, so we get

$7x+6x+5x=162\\\\\Rightarrow 18x=162\\\\\Rightarrow x=\dfrac{162}{18}\\\\\Rightarrow x=9.$

Therefore, the length of the longest side is given by

$7x=7\timex9=63.$

Thus, the required length of the longest side is 63 inches.

We have five samples of data: sample A with 30 successes of 50 cases, sample B with 600 successes of 1000 cases, sample C with 3

faust18 [17]

Answer:

C. with 3000 successes of 5000 cases sample

Step-by-step explanation:

Given that we need to test if the proportion of success is greater than 0.5.

From the given options, we can see that they all have the same proportion which equals to;

Proportion p = 30/50 = 600/1000 = 0.6

p = 0.6

But we can notice that the number of samples in each case is different.

Test statistic z score can be calculated with the formula below;

z = (p^−po)/√{po(1−po)/n}

Where,

z= Test statistics

n = Sample size

po = Null hypothesized value

p^ = Observed proportion

Since all other variables are the same for all the cases except sample size, from the formula for the test statistics we can see that the higher the value of sample size (n) the higher the test statistics (z) and the highest z gives the strongest evidence for the alternative hypothesis. So the option with the highest sample size gives the strongest evidence for the alternative hypothesis.

Therefore, option C with sample size 5000 and proportion 0.6 has the highest sample size. Hence, option C gives the strongest evidence for the alternative hypothesis

Help ASAP. Thank you! Find the area of the shaded region. 80° 5 cm A=[?] cm2

pashok25 [27]

Answer:

Step-by-step explanation:

$\text{The area shaded outside of the triangle is}\\ \\ A=\frac{\pi r^2\theta}{360},\ r=5,\ \theta =80^o\\ \\ A=\frac{50\pi}{9}\\ \\ \text{Then we must add the area of the shaded triangle.}\\ \\ A=\frac{bh}{2}\\ \\ \frac{b}{2}=5sin40^o\\ \\ h=5cos40^o\\ \\ A=25sin40^o(cos40^o)\\ \\ \text{Total area is}\\ \\ A=\frac{50\pi }{9}+25sin40^o(cos40^o)\\ \\ A\approx 29.8cm^2$

What do I put in the boxes if the answer is 1.74%?

gavmur [86]

If a credit card advertises an annual interest rate of 23%, then the equivalent monthly interest rate is 1.74%

The annual interest rate = 23%

The credit card interest rate the amount you have to pay to borrow the money from them. The credit card interest rate is usually expressed in yearly rate. This is called annual percentage rate.

The monthly interest rate = $(1+\frac{23}{100})^{(1/12)}$

= $(1+0.23)^{(1/12)}$

= 1.0174

Then,

= (1.0174-1) × 100%

Subtract the terms first

= 0.0174 × 100%

Multiply it

= 1.74%

Hence, if a credit card advertises an annual interest rate of 23%, then the equivalent monthly interest rate is 1.74%
