Answer:

179.9

Step-by-step explanation:

First, plug in the numbers for the variables.

12.1(7) + 11.9(8)

Then, multiply.

12.1 x 7 = 84.7

11.9 x 8 = 95.2

rewrite your equation and add.

84.7 + 95.2 = 179.9

Hope This Helps!!

Find the missing value given (-1,7)(-3,d) m= 6 HELP ASAP WILL MAKE BRAINLEST
-Dominant- [34]

Answer:

d= -5

Step-by-step explanation:

The slope of a line is found by finding the ratio of change is y values to change is x values

m=y_2-y_1/x_2-x_1

The points on the line have coordinates at: (-1,7) (-3,d)

where ;

y_2=d, y_1=7,x_2=-3,x_1=-1,m=6

Applying the formula with values as;

6=\frac{d-7}{-3--1} \\\\6=\frac{d-7}{-3+1} \\\\6=\frac{d-7}{-2} \\\\6*-2=d-7\\\\-12=d-7\\\\-12+7=d\\\\-5=d

The value of d = -5

The coordinates of the points  (-1,7) (-3,-5)

densk [106]

a. The population for the study is a total of 1000 adults, so the 50% that favored the plan made up a total of 500 people, since 500 is 1/2 (or 50%) of 1000.

b. The percentage provided is an inferential statistic. Inferential statistics are made by taking a sample of a population and using that sample as data used to make inferences/predictions. Since the percentage provided is a sample of a population being used to make a prediction, it is an inferential statistic.

Answer:

15.13cm

Step-by-step explanation:

From that above question:

We are told that:

Lateral surface area of a right circular cone : πr√r² + h²

We are give the following parameters:

Lateral surface area = 236.64cm²

Radius = 4.75cm

We are to find the height

Making h the subject of the formula

h = √[(A/r)² - πr²]/π

h = √[(236.64/4.75)²- π ×4.75²]/π

h = 15.12975 cm

Approximately to the nearest hundredth = 15.13cm
