The javelin will hit the ground 14.66 or 15 seconds upon Maria's release from the said distance. The computation are as follows: 

time = distance/speed (d/m)
time = 22 meters/second / 1.5 meters 
time = 14.66 seconds or 15 seconds

Step-by-step explanation:

  • 5^-2= 1/25 (as when taken up 25 it becomes 5^-2).
  • 2^5= 32 (when we multiply 2 for 5 times, we get 32).(2×2×2×2×2)
  • 2^-4=1/16 (as when we take up 16 we get 2^-4)
  • 5^3=125 (when we multiply 5 for 3 times we get 125)(5×5×5)

-3² = -1*3² = -1 * 9 = -9 (order of operations) while (-3)² = (-3)(-3) = +9 or 9
mixas84 [53]

Answer:   20

Step-by-step explanation:

Assuming your question is:

Z² - X² - XY     X = -2, Y = 3, Z = -4

Substitute values

(-4)² - (-2)² - {(-2)(3)}

{(-4)(-4)} - {(-2)(-2)} - (-6)

(16) - (4) + 6

16 - 4 + 6

In order to make statistical inferences when testing a population proportion p, which of the following conditions verify that in
sweet [91]

Answer:

a, b and c.

Step-by-step explanation:

The statistical inference may be defined as the process of using the data analysis to infer the properties of an underlying distribution for a probability.

In the context, for testing the population proportion p, the following conditions are used to verify the inference procedures so as to make the statistical inferences :

-- data that are collected by a random assignment or by a random sample.

-- sample size should be less than 10% of population size.

-- The $n \ p_0 \geq 10$ and the $n(1-p_0) \geq 10$ for the sample size $n$ as well as for the  hypothesis proportion, $p_0.$

G(z) = 3z + 8<br> g(2w) =
Dima020 [189]

Answer:

g(2w)=6w+8

Step-by-step explanation:

We know that g(z)=3z+8

And we want to find g(2w)

So, we will simply substitute <em>2w</em> for <em>z</em>. This yields:

g(2w)=3(2w)+8

Distribute. Therefore:

g(2w)=6w+8
