Answer:

Step-by-step explanation:

the value of the expression is equal to 1. because any number raised to 0 is 1. it doesn't matter whats inside the bracket. if it is raised to 0. then its value =1.

if you want to change the expression not to be equal to 1. just replace the 0 power to any other number like 1,2,3 any number as you like.

An environmentalist wants to find out the fraction of oil tankers that have spills each month. Step 1 of 2 : Suppose a sample of

Elenna [48]

Answer:

p = 0.299

Step-by-step explanation:

A proportion is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

We want to estimate the proportion of oil tankers that had spills. Of the 1453, 1018 did not have spills, and 1453 - 1018 = 435 had. So $D = 435$

Total outcomes:

All the 1453 tankers, so $T = 1453$

Estimating the proportion

$p = \frac{D}{T} = \frac{435}{1453} = 0.299$

Find (3a2 - 2a + 4) - (a2 - 3a + 7) .

melisa1 [442]

<span>(3a^2 - 2a + 4) - (a^2 - 3a + 7) = (distribute the negative sign)
3a^2 - 2a +4 - a^2 + 3a - 7 = (add like terms)
2a^2 + a - 3
So, the answer is A!

01.01) Rewrite the expression with rational exponents as a radical expression. 7 times x to the two thirds power cube root of th

jeka94

Answer:

$(7x)^{\frac{2}{3} = (\sqrt[3]{7x})^2$

Step-by-step explanation:

Given the expression $(7x)^{\frac{2}{3}$ , to express this as a radical expressions, we'd apply the rule/law of indices that deals with converting expressions that has rational exponents into radical expressions.

The rule of indices to apply is: $b^{\frac{m}{n}} = (\sqrt[n]{b})^m$

To apply this to the expression, $(7x)^{\frac{2}{3}$ , the denominator of the fraction of the exponent would determine the root, that is, cube root in this case. The numerator of the exponent would then determine the exponent of the radical expressions.

Thus:

$(7x)^{\frac{2}{3} = (\sqrt[3]{7x})^2$
