Jimmy borrowed $450 to start a lawn-mowing business. He charges $35 per lawn and it costs him $8 in operating costs per lawn.

Akimi4 [234]

Answer: $450

Step-by-step explanation:

Given that:

Amount borrowed = $450

Amount charged per lawn = $35

Operating cost per lawn = $8

Jimmy's cost (C(x)) :

Amount borrowed + operating cost

If x lawns are mowed :

$450 + $8 per lawn

$450 + $8x

C(x) = 450 + 8x

Intercept (value of y when x = 0

Value of C(x) ; when x = 0

C(x) = 450 + 8(0)

C(x) = 450 + 0

C(x) = 450

A weather forecast states that there is a 20% probability of rain in the next three days. Describe a simulation you could perfor

iVinArrow [24]

Answer:

my hands hurt, pls give brainilist and hope this helps

Step-by-step explanation:

Before leaving for work, Victor checks the weather report in order to decide whether to carry an umbrella. The forecast is “rain" with probability 20% and “no rain" with probability 80%. If the forecast is “rain", the probability of actually having rain on that day is 80%. On the other hand, if the forecast is “no rain", the probability of actually raining is 10%.

1. One day, Victor missed the forecast and it rained. What is the probability that the forecast was “rain"?

2. Victor misses the morning forecast with probability 0.2 on any day in the year. If he misses the forecast, Victor will flip a fair coin to decide whether to carry an umbrella. (We assume that the result of the coin flip is independent from the forecast and the weather.) On any day he sees the forecast, if it says “rain" he will always carry an umbrella, and if it says “no rain" he will not carry an umbrella. Let U be the event that “Victor is carrying an umbrella", and let N be the event that the forecast is “no rain". Are events U and N independent?

3. Victor is carrying an umbrella and it is not raining. What is the probability that he saw the forecast?

One face of a cube-shaped package has an area of 7 5/8 square inches what is the lateral surface area of the package in square i

tamaranim1 [39]

Answer:

232.57 square inches

Step-by-step explanation:

The computation of the lateral surface area of the package in square inches is shown below;

Let us assume the area of cube is a

Given that

a = $7 \frac{5}{8}\ in^2$

As we know that in a cube there is a four faces so the lateral surface area would be

$= 4a^2\\\\=4\times 7\frac{5}{8} ^2\\\\= 4\times (\frac{61}{8})^2\\\\= 4\times \frac{3721}{64} \\\\= 232.57$

= 232.57 square inches

Write an equation in slope-intercept form for the line parallel to y= 9x+2 that passes through the point (-2,8). Show your work.

Ymorist [56]

Answer: y=9x + 26

Step-by-step explanation:

Notice that for two lines to be parallel they must have the same slopes but different y intercept.

So the equation y =9x + 2 has a slope of 9 and y-intercept of 2 so using the points we can determine the y intercept of the line parallel to it to find the.

Using the slope intercept form formula which is y = mx + b we can plot in the slope and the given coordinates to solve for b.

The coordinate is (-2,8) which the y value is 8 and the x value is -2

so 8 = 9(-2) +b solve for b

8 = -18 + b

+18 +18

b = 26

The y intercept is 26 so the equation will be y=9x + 26
