Step-by-step explanation:

From the Pythagorean theorem we have:

a^2+b^2=c^2           <em>subtract b² from both sides</em>

a^2=c^2-b^2\to a=\sqrt{c^2-b^2}

Same:

b=\sqrt{c^2-a^2}

A taco stand sells tacos for $3.25 each. The stands expenses for the day are $210. Define your variables and write an inequality
Julli [10]
Given:

Let P= profit
let n= no. of tacos sold per day

Sol'n:

P= 3.25n-210
the profit needs to be positive, thus

3.25n>210

n>210/3.25

n> 64.615

they can only sell whole tacos, therefore they must sell at least 65 tacos to make a profit and that profit is:

P=3.25n-210

P=3.25*65 - 210

P= 211.25 -210

P= 1.25

$1.25 profit

The surface area of a cube is found using the formula sa=6s^2, where s is theside length if the surface area of a cube is 294 sq
aleksley [76]
<span>6s^2 = 294
Solve for s

Solve for s:
6 s^2 = 294
Divide both sides by 6:
s^2 = 49
Take the square root of both sides:
Answer:  s = 7 m

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> °
Gnom [1K]

Answer:

The answer to your question is:  111°

Step-by-step explanation:

The sum of the interior angles of a polygon is (n - 2) 180°

This polygon has 7 sides

Then n = 7

Process

  120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180

  120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)

  789 + x = 900

  x = 900 -789

  x = 111°

Consider the one-sided confidence interval expressions for the mean of a normal population. Round your answers to 2 decimal plac
ser-zykov [4K]

Answer: a) 0.84  b) 0.67  c) 1.28

Step-by-step explanation:

Using the standard normal distribution table for z-value , we have

(a) The value of z_{\alpha} would result in a 80% one-sided confidence interval : z_{(1-0.80)}=z_{0.20}=0.8416\approx0.84

(b) The value of z_{\alpha} would result in a 85% one-sided confidence interval : z_{(1-0.85)}=z_{0.25}=0.6744897\approx0.67

(c) The value of z_{\alpha} would result in a 90% one-sided confidence interval : z_{(1-0.90)}=z_{0.10}=1.2815515\approx1.28
