Mathematics

To solve equations, all we must do is isolate the variable and simplify. In this case, we need to get rid of the "/7" because it i with our "e." To do this, we should do the reverse operation of "/7" on both sides, and them simplify.

-5=e/7
*7   *7
-35=e

Using the math above, we can see that e=-35.

If we're solving for "e" than follow these steps (if you want to) 

Problem: -5 =  \frac{e}{7}

Step^1: go through all of the factors of 5 or 7 to find your answer  (you don't have to do this step if you don't want to) 
7(-1)= -7 \\ 7(-2) = -14 \\ 7(-3)= -21 \\ 7(-4) = -28\\ 7(-5)= -35 \\ \\  OR  \\ \\  \frac{7}{-1} = -7 \\  \frac{-14}{7} = -2 \\  \frac{-21}{7} = -3 \\  \frac{-28}{7} = -4\\  \frac{-35}{7} = -5

Answer: 
e = -35

Good luck on your assignment and have great day

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting he
kondor19780726 [428]

Use the formula h(t) = -16t^2 + vt + s,

where t = time in air,

v = starting upward velocity,

s = the objects starting height.

from ground (s), the starting height is 0,

the ball's initial velocity (v) 25 feet per second

Solve:

v - 16t^2 + (25)t + 0

= -16t^2 + 25t. 0

Factor:

= -16t^2 + 25t

Find GCF:

0 = -16t^2 + 25t

Divide both sides by (t)

t(-16 + 25) = 0

t = 0; -16 + 25 = 0

Now Subtract 25 from both sides of equation:

-16 = -25

divide both sides by -16 to get -25/-16

= 1.56

Rounds to 1.60, or 1.6

Answer: 1.6 Seconds it will take for soccer ball to hit the ground again.

First part of the Equation: Answer: 9.8Ft. Soccer ball will reach at maximum height.

Hope that helps!!!! : )

Zina [86]

Answer:

Step-by-step explanation:

Given that a machine produces defective parts with three different probabilities depending on its state of repair.

condition             Good order         Wearing down               Needs main   Total

Prob                       0.8                            0.1                                   0.1              1

Defective               0.02                          0.1                                   0.3

Joint prob              0.016                         0.01                                0.03        0.056

a) 0.016

b) total = 0.056

c) If not defective from needs maintenance

Prob for not defective = 0.8*0.98+0.1*0.9+0.1*0.7\\=0.784+0.09+0.07\\=0.944

From machine that needs maintenance = 0.07

So reqd prob = \frac{0.07}{0.944} \\=0.0741
