The Third Side Is Called The base if an isosceles triangle has perimeter 345 cm and base length 85 cm what is the length of each
maks197457 [2]

Answer:

Length of each leg = 130 cm.

Step-by-step explanation:

Given that there is an isosceles triangle which has perimeter 345 cm.

Base length =85 cm.

Since other two sides are equal, let the equal size = x

Perimeter = sum of all 3 sides of a triangle

= 85+x+x = 85+2x

But perimeter = 345 (given)

So equate x term perimeter with actual

85+2x = 345

Subtract 85

2x = 260

Divide by 2

x =130 cm.

Hence answer is 130 cm.

Elanso [62]

Answer:

A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 39 - 1 = 38

Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99(t_{99}). So we have T = 2.0244.

A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean

Find the inverse of the function.
asambeis [7]

Answer:

A) f^{-1}(n)= (n+2)^3

Step-by-step explanation:

f(n) = \sqrt[3]{n} -2

y = \sqrt[3]{n} -2

y = n^{1/3}-2

n = y^{1/3} -2

n + 2 = y^{1/3}

y = (n + 2) ^3

f^{-1}(n) = (n + 2)^3

Hope this helps!
