Given:

The expression is:

\sqrt{1.69}-\sqrt[3]{0.001}

To find:

The value of the given expression.

Solution:

We have,

\sqrt{1.69}-\sqrt[3]{0.001}

On simplification, we get

\sqrt{1.69}-\sqrt[3]{0.001}=1.3-0.1

\sqrt{1.69}-\sqrt[3]{0.001}=1.2

Therefore, the value of the given expression \sqrt{1.69}-\sqrt[3]{0.001} is 1.2.

A sample of men's heights was taken and the mean was 68.8 inches. The standard deviation is 2.8 inches. What percent of the men
jarptica [38.1K]

Answer:

87.29%

Step-by-step explanation:

Given: Mean= 68.8 inches

           Standard deviation= 2.8 inches

           

Now, finding the percent of the men in the sample were greater than 72 inches.

We know, z-score= \frac{x-mean}{standard\ deviation}

z-score= \frac{72-68.8}{2.8}

⇒ z-score= \frac{3.2}{2.8} = 1.14

∴ z-score= 1.14

Next, using normal distribution table to find percentage.

Coverting 0.8729 into percentage= 0.8729\times 100

We get the percentage as 87.29%

Hence, 87.29% of the men in the sample were greater than 72 inches.

How do I solve 6(5 - 2x) + 12 = -66?
ladessa [460]

Answer:

x = 9

Step-by-step explanation:

Step 1: Write equation

6(5 - 2x) + 12 = -66

Step 2: Solve for <em>x</em>

  1. Distribute 6: 30 - 12x + 12 = -66
  2. Combine like terms: 42 - 12x = -66
  3. Subtract 42 on both sides: -12x = -108
  4. Divide both sides by -12: x = 9

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

6(5 - 2(9)) + 12 = -66

6(5 - 18) + 12 = -66

6(-13) + 12 = -66

-78 + 12 = -66

-66 = -66
