In this case, we must use trigonometry to find the value of x:

$tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24$

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!

If square root m= 8, then m must equal ____. 4. 8. 16. 64

Whitepunk [10]

Answer:

Step-by-step explanation:

To find m, it has given you √x = 8. The opposite of a square root is squaring (exponentials). Simply just square 8 and you should get x = 64. You can check by square rooting 64, and you should get 8.

A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard de

hjlf

Answer:

The answer is below

Step-by-step explanation:

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

$z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

$z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16$

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%

Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

Is 16to 14 and 64to60 equivalent

stiks02 [169]

NO. They are not.

We can prove this by turning those numbers into fractions:

16 / 14 = 1.1428 ; 64 / 60 = 1.0667

Or simply:

64 / 16 = 4
60 / 14 = 4.29

To get the equivalent of 16 to 14; we must multiply both numbers by 4.

16 * 4 = 64
14 * 4 = 56

The equivalent of 16 to 14 is 64 to 56.
