Answer:

Haeather ran at a speed of 5 miles per hour.

Step-by-step explanation:

Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:

48/4 = 12

Thus, Haeather ran 1 mile every 12 minutes.

60/12 = 5

1 x 5 = 5

Therefore, Haeather ran at a speed of 5 miles per hour.

Step-by-step explanation:

100 is more than 20

Answer:

Let the three numbers be a,ar, ar^2 ,

where r is the common ratio.

⇒a+ar+ar^2 =28 and a^3 r^3 =512

⇒ar=8⇒a+ar^2 =20

⇒8r^2 −20r+8=0

⇒r=2,r= 1/2

If r=2,a=4

Therefore, the three numbers are 4,8,16.

Answer:

1. Mean => 8.2

2. Modal class => 7 - 9

Step-by-step explanation:

From the question given above, the following data were obtained:

Days >>>>>> Frequency

1 - 3 >>>>>>> 6

4 - 6 >>>>>> 8

7 - 9 >>>>>> 10

10 - 12 >>>>> 7

13 - 15 >>>>> 0

16 - 18 >>>>> 5​

Next, we shall determine the the day mark.

The day mark is obtained by adding the the lower and upper class intervals and diving the result by 2.

This is illustrated below:

Days >> Day mark >>> Frequency

1 - 3 >>> 2 >>>>>>>>>> 6

4 - 6 >>> 5 >>>>>>>>> 8

7 - 9 >>> 8 >>>>>>>>> 10

10 - 12 >> 11 >>>>>>>> 7

13 - 15 >> 14 >>>>>>>> 0

16 - 18 >> 17 >>>>>>>> 5

1. Determination of the mean.

Summation of (day mark × frequency) = (2×6) + (5×8) + (8×10) + (11×7) + (14×0) +(17×5)

= 12 + 40 + 80 + 77 + 0 + 85

= 294

Summation of frequency = 6 + 8 + 10 + 7 + 0 + 5

= 36

Mean = Summation of (day mark × frequency) / Summation of frequency

Mean = 294 / 36

Mean = 8.2

2. Determination of the modal class.

The modal class is simply the class with the highest frequency.

Days >>>>>> Frequency

1 - 3 >>>>>>> 6

4 - 6 >>>>>> 8

7 - 9 >>>>>> 10

10 - 12 >>>>> 7

13 - 15 >>>>> 0

Considering the data given above, the class with the highest frequency is 7 - 9.

Thus, the modal class is => 7 - 9

when u look at the differance between 7 and 2 you get 5 and its goes low number to high in 2, 7 and 9-4=5 too and you do low to high!

Answer:

Step-by-step explanation:

Plug in the values of x in the equation and find the value of y

6) y = - 3x + 5

Plugin x = -1 , y = -3*(-1) + 5 = 3 + 5 = 8     (-1 , 8)

Plugin x = 1 ;  y = -3*1 + 5    = - 3 + 5 = 2   (1, 2)

Plugin x = 3 ; y = -3*3 + 5 = -9 + 5   = -4   (3,  -4)

Plugin x = 4 ; y  = -3*4 + 5 = -12+5  = -7   (4 , - 7)

7) y = -4x

Plugin x = -2 ; y = -4*(-2) = 8          (-2 , 8)

Plugin x = -1 ; y = -4 *(-1) = 4          (-1 , 4)

Plugin x = 0 ; y = 0                       (0 , 0 )

Plugin x = 2; y = -4*2 = -8            (2 , -8)

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser

say we did 3.13 as our first number

3.13 - 3.12 = 0.01

this means that 3.13 is greater by 0.01, if we switch the two numbers however...

3.12 - 3.13 = -0.01

then that means that 3.12 is lesser by 0.01

i hope this makes sence, working with decimals may get tricky sometimes lol

Yes, 3.13 is greater than 3.12.

A decimal number is a number in which whole number part is separated from a decimal.

We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.

In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.

Hence 3.13 is greater than 3.12.

Answer:

None of the above ? （the equation should be y=12）

Step-by-step explanation:

the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.

Answer:

D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.

Step-by-step explanation:

Got it right on unit test review

The probability of it occurring by chance alone is not unlikely.

We have given that,

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31.

repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random.

The sample was completed in under an hour.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317.

D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
