Answer:

25%

Step-by-step explanation:

The question aks: What percentage of 64 is 16?

Let that percentage be x,

$\frac{x}{100}$ of 64 = 16

We multiply both sides by 100 then divide by 64 to get:

x = $\frac{1600}{64}$ = 25%

Please Help me Find NM using Secant

kondaur [170]

Answer:

NM = 15

Step-by-step explanation:

There is a property of secants and tangents to a circle where:

The square of the tangent length is equal the length of the external segment of the secant times the whole secant length.

Therefore, in our question, we have that:

$NM^2 = ML * MK$

The values of NM, ML and MK are:

$NM = x + 3$

$ML = x - 3$

$MK = ML + LK = x - 3 + 16 = x + 13$

So we have:

$(x+3)^2 = (x - 3)(x + 13)$

$x^2 + 6x + 9 = x^2 + 10x - 39$

$6x + 9 = 10x - 39$

$4x = 48$

$x = 12$

So the length of NM is:

$NM = x + 3 = 12 + 3 = 15$

Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college. You survey 10

neonofarm [45]

Answer: 1.460

Step-by-step explanation:

Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.

Let $\mu$ represents the population mean .

Then, the set of hypothesis will be:-

$H_0: \mu=15$

$H_a:\mu\neq15$

We assume that this is normal distribution.

Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.

Sample mean : $\overliene{x}=16.2\ lbs$

Standard deviation : $\sigma=2.6$

The test statistic for population mean for small sample is given by :-

$t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t=\dfrac{16.2-15}{\dfrac{2.6}{\sqrt{10}}}=1.45951276623\approx1.460$

Hence , the value of test statistic = 1.460
