Jeanette surveyed 2 newly hired police officers at the police station.

Is this sample of the police officers at the police station likely to be representative?

Answer as Yes or No

Answer:

to get more of ur dogs walked

The mean will be equal to 30.5 for the dog walker.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

The given data is:-

40+50+30+40+15+25+15+20+30+40

Now the mean will be calculated as:-

Mean = (40+50+30+40+15+25+15+20+30+40) / 10

Mean = 305 / 10

Mean = 30.5

Therefore the mean will be equal to 30.5 for the dog walker.

Answer:

The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.

Step-by-step explanation:

Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.

2/10 = 0.2 chairs per minute

Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.

5/0.2 = 25 minutes

It takes the machine 25 minutes to make 5 chairs.

Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.

32/0.2 = 160 minutes

It takes the machine 160 minutes to make 32 chairs.

Answer:

$108

Step-by-step explanation:

18 dollars times 6 equals 108.

Answer:

108 dollars

Step-by-step explanation:

Since so far Caleb saved $18 and the skateboard he wants to buy is 6 times as great as the amount he saved, then you multiply 18 and 6 together which equals $108.

Therefore, the cost of his skateboard is $108.

Answer:

2. Surface Area = 576m^2

3. Surface Area = 300 yd^2

Step-by-step explanation:

2.

Surface Area of Prism Formula:

Triangle Formula: Area = 1/2 * Base * Height

Left Triangle: Area = 1/2 * 8m * 6m = 1/2 * 48 = 24 m^2

Right Triangle:  Area = 24m^2

Rectangle Formula: Area = Length * Width

Top Rectangle: Area = 22m * 6m = 132m^2

Middle Rectangle: Area = 22m * 8m = 176m^2

Bottom Rectangle: Area = 22m * 10m = 220m^2

Add Total Surface Area:

Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect

Surface Area = 24  + 24 + 132 + 176 + 220

Surface Area = 576 m^2

3.

Surface Area of Prism Formula:

Triangle Formula: Area = 1/2 * Base * Height

Left Triangle: Area = 1/2 * 9yd * 4yd = 1/2 * 36 = 18 yd^2

Right Triangle:  Area = 18 ydm^2

Rectangle Formula: Area = Length * Width

Top Rectangle: Area = 12yd * 8yd = 96yd^2

Middle Rectangle: Area = 12yd * 5yd = 60yd^2

Bottom Rectangle: Area = 12yd * 9yd = 108yd^2

Add Total Surface Area:

Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect

Surface Area = 18 + 18 + 96 + 60 + 108

Surface Area = 300 yd^2

Answer:

Step-by-step explanation:

Graph the points and draw an aproximate line of fit that includes two of the points. Then using point-slope form find the linear equation of that line.

10-(-4)=m(-5-4) is 14=m(-9) solve for m and find the slope is aproxx -14/9 or -1.555. Then do some fancy math to find your y intercept and you come out with an aproxx line of fit of y=(-14/9)x+(20/9). Or you could plug these points into excel and have it spit out a trendline of y=(-1.26)x+(0.467)

Answer:

#1

Step-by-step explanation:

I am just guessing but its probably #1

Answer:

the answer is the 1st one

Step-by-step explanation:

Answer:

the A is 4.36

Step-by-step explanation:

1. you have to divide 81/49 and is equal to 1.65. 2. so 7.2 is b, this mean for find A we have to divade, 7.2/1.65, so is equal to 4.36.

The first step that we must take before attempting to solve a problem is to understand what the problem statement is asking from us and what is given to us to help accomplish that goal.  Looking at the problem statement, it asks us what the probability of choosing a vegetable is.  We are given information about how many dishes of each type of food there is out of 10 dishes.

The next step that we need to do is to collect the total amount of vegetable dishes that have been listed in the problem statement along with the total amount of dishes.  We know that there are 10 covered dishes and that there are 2 broccoli and 2 carrot which adds up to 4 vegetable dishes.

Now that we have that information we can move onto the final part which is to determine the probability of choosing a vegetable dish.  We can do this by dividing the total amount of vegetable dishes from the total amount of dishes.

Determine the probability

Therefore, looking at the options that best matches the answer that we got we can confidentially say that it is option A, 2/5.

[tex]\huge\text{Hey there!}[/tex]

[tex]\text{Your equation: }\rm{\dfrac{number\ of\ the\ vegetables (the\ carrots\ \& \ the \ broccolis)}{total\ meals\ you\ have\ all\ together} = probability}\\\\\rm{\dfrac{2\ carrots + 2 \ broccolis}{10\ meals} = probability}\\\\\text{2 + 2 = \boxed{\mathbf 4} , right?}\\\\\rm{\dfrac{4}{10} = probability}\\\\\rm{\dfrac{4\div2}{10\div 2} = probability}\\\\\rm{\dfrac{2}{5} = probability}\\\\\\\huge\text{Therefore, your answer should be: \boxed{\mathsf{\dfrac{2}{5}}}}\huge\checkmark[/tex]

Answer: (C) 37.68 m

Step-by-step explanation:

    We can use a formula to help us solve for the circumference of this circle.

        C = 2πr

        C = 2π(6)

        C ≈ 37.68 m

The circumference is about 37.68 m, so the answer to your question is option C.

Answer: A is farther away from C

Step-by-step explanation:

If BC = EF, then AC has to be greater than EF. This is because A is farther away from B from C
