Find the diameter of a circle that has an area of 254.34mm2

1 answer:

5 0

To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient

$\frac{254.34}{3.1415} = 80.95$
$\sqrt{80.95} = 8.99$
That is the radius now just times that by 2 so 2 x 8.99 = 17.98

Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18

Please help me with this<br> simplify sqrt24w^14

Serjik [45]

Answer:

2×sqrt(6)×w⁷

Step-by-step explanation:

what I can read here, you need to simplify

sqrt(24×w¹⁴)

= sqrt(24)×sqrt(w¹⁴) = sqrt(4×6)×sqrt(w¹⁴) =

= 2×sqrt(6)×sqrt(w¹⁴)

and taking the square root of something with exponent simply means dividing that exponent by 2

so,

2×sqrt(6)×w⁷

A well know Statistical Institution claims that the average College tuition for a law degree costs at least thirty five thousand

kirill [66]

Step-by-step explanation:

Below are the null and alternative Hypothesis,

Null Hypothesis, H0: μ = 35000

Alternative Hypothesis, Ha: μ < 35000

Test statistic,

z = (xbar - mu)/(sigma/sqrt(n))

z = (33450 - 35000)/(5978/sqrt(50))

z = -1.83

P-value Approach

P-value = 0.0336

As P-value >= 0.02, fail to reject null hypothesis.

There is not sufficient evidence to conclude that the average College tuition for a law degree costs at least thirty five thousand dollars.
