Answer:
y=5/2x+2
Step-by-step explanation:
To get the slope,
(-5-0) /(0-2)=-5/-2=5/2
Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.

According to the guideline from the Health Department, every over-weight child needs to take a fitness test.
Every ten over-weight children would be randomly grouped together to attend the fitness test. According to
the past experience, the probability for each child to pass the fitness test is 0.75 and whether a child can pass
the test is independent with the test result of other children.
(a) Many test sessions will be conducted regularly, each with 10 independent children. Find the expectation
and standard deviation of the number of children can pass the fitness test in a test session.
(b) Most likely, how many children can pass the fitness test in a test session? Justify your answer by
comparing the two outcomes with the relatively high probability.
(c) Find the probability that less than 8 children can pass the fitness test in one test session.
Answer:

What is the perimeter of the rectangle shown?
Answer:
74
Step-by-step explanation:
14+14+23+23=74
Opposite sides of a rectangle are congruent or have the same length.
Now, the perimeter of a rectangle is just the
distance around the outside of the figure.
So we add up the dimension, which are the length and width.
So we have 14 + 14 + 23 + 23 which is 74 yd.

How many times larger is 1.2*10^8 than 6*10^3
Answer:
1.2×10⁸ is greater than 6×10³ by a factor of 2×10⁴, or 20000.
Step-by-step explanation:
You can solve this simply by dividing the first one by the second one:
[tex]\frac{1.2\times 10^8}{6\times 10^3} \\\\= \frac{1.2}{6} \times \frac{10^8}{10^3} \\\\= \frac{12}{6} \times \frac{10^7}{10^3} \\\\= 2.0 \times 10^4 \\\\[/tex]

We need to find the perimeter of the garden.
Perimeter of rectangle:
P= 19*2+29*2
P= 38+58
P= 96 ft
Perimeter of semicircle:
The diameter is 19ft
P= π*d
P= 3.14*9.5
P= 29.83 ft
Perimeter of the garden:
96+29.83
= 125.83 ft
So the fence has to be 125.83 ft

1. A ball is kicked up from a platform 36 feet above the ground. The height of
the ball h(t) above the ground (measured in feet) can be modeled by the
function h (t)
-3t2 + 12t + 36, where t represents the amount of time
(in seconds) since the ball was kicked. How long to the nearest second did it
take the ball to hit the ground?
-
seconds to hit the ground
Answer:6
Step-by-step explanation:
So when the ball hits the ground -3t^2+12t+36 must equal 0
So you can factor a -3 out
-3(t^2-4t-12)=0
Factor -3(t-6)(t+2)=0
T-6=0 t+2=0
T=6 t=Negative 2
And since time can’t be negative the answer is 6
