Answer:

B) y=-4x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-0)/(0-1)

m=4/-1

m=-4

y-y1=m(x-x1)

y-0=-4(x-1)

y=-4(x-1)

y=-4x+4

Answer:

B

Step-by-step explanation:

rise over run gives you 4/1 which equals 4. and the only 2 intercepts given lead negatively so the line has to be negative which gives you -4 then where x=0 is the x intercept which is positive 4

MArishka [77]

There are different ways to estimate a variable. The sample mean is a point estimate of the population mean for the variable of interest.

<h3>What is a point estimate of the population mean?</h3>

A point estimate is known to be the value of a sample statistic that is often applied as one estimate of a specific population parameter.

The sample mean is defined simply as a form of average value seen in a sample. A sample is known to be the little portion of a whole.

HELP PLEASE!
Nataliya [291]
The answer is C.

The probability of a hit is 127/369 This includes home runs.The probability of a home run is 21/369 = 7/123The probability of a hit that is not a home run is (127-21)/369 = 106/369The probability of no hit is (369-127)/369 = 242/369 Now,If Miguel hits a home run, he'll score 5 pointsIf Miguel has a hit that is not a home run, he'll score 1 pointIf Miguel does not get a hit, he'll score 0 points. Expected value of his score at each at bat is(0) 242/369 + (1) 106/369 + (5) 21/369106/369 + 105/369 = 211/369 = .57

The city is planning to add a fish pond to a neighborhood park. The figure below is a drawing of the fish pond. Its scale is 1/2
faust18 [17]

Answer:

Part a) The area of the actual fish pond is 2,956.50\ ft^{2}

Part b) The length of the fence will be 244.20\ ft

Step-by-step explanation:

we know that

The scale drawing is

\frac{(1/2)}{15}\frac{in}{ft}=\frac{1}{30}\frac{in}{ft}

step 1

Find the actual dimensions of the fish pond

To find the actual dimensions divide the measure of the drawing by the scale drawing

0.5\ in=0.5/(1/30)=15\ ft

1\ in=1/(1/30)=30\ ft

2.5\ in=2.5/(1/30)=75\ ft

step 2

Find the area of the actual fish pond

The area of the fish pond is equal to the area of a circle p[lus the area of rectangle

A=\pi r^{2} +bh

we have

r=15\ ft

b=75\ ft

h=30\ ft

substitute

A=(3.14)(15)^{2} +(75)(30)=2,956.50\ ft^{2}

step 3

Find the length of the fence around the entire fish pond

The perimeter of the fish pond is equal to the circumference of a complete circle plus the length of 75 ft two times

so

P=2\pir+2(75)

we have

r=15\ ft

substitute

P=2(3.14)(15)+2(75)=244.20\ ft
