Answer:

p = 3k

45cm

Step-by-step explanation:

Since all sides of an equilateral triangle are equal, to find perimeter, you multiply the number of sides by the length of one side.

So the equation would be p = 3k (k represents the side length and 3 is the number of sides)

If a equilateral triangle has a side length of 15, you just multiply 15 by the number of sides.

3 (15cm) = 45cm

50 1/2 divided by 1/4 = 202<br> How are the numbers related?
Stels [109]

Answer:

see the explanation

Step-by-step explanation:

Let

x=50\frac{1}{2}=\frac{50*2+1}{2}=\frac{101}{2}

y=\frac{1}{4}

Find the ratio x/y

\frac{x}{y}=\frac{(101/2)}{(1/4)} =\frac{101*4}{2*1}=202

therefore

\frac{x}{y}=202

x=202y

That means----> The first number (50 1/2) is 202 times greater than the second number (1/4)

To save money, a local charity organization wants to target its mailing requests for donations to individuals who are most suppo
Naya [18.7K]

Answer:

(0.55525, 1.24475)

Step-by-step explanation:

Given that to save money, a local charity organization wants to target its mailing requests for donations to individuals who are most supportive of its cause.

                     Men    women

Sample size      5        5

Mean rate        6.2     5.3

Mean diffference = 6.2-5.3=0.9

Std error for difference = 0.25 (given)

Since we have two groups and also sample sizes are very small we can use t significant value for finding out confidence interval

df = 5+5-2 =8

t critical value for 80% two tailed = 1.397

Conf interval 80%

=(0.9-1.397*0.25, 0.9+1.397*0.25)\\= (0.55525, 1.24475)
