someone pls help me 10 points

Wll not just this question, but whenever you need to find average, you have to:

Wait, for example let's take ur question:

1st step we will add up all the values aka heights:

5.4+6.12+7.02+4.9+6.25=29.69

And then how many values did you take???

Its, 5 values

1st value= 5.4

2nd value=6.12

aaand so on....

However, then we will have to divide the sum by no.of values

29.69÷5=5.938

Aaand this is your FINAL ANSWER

Done!!!!

Hope I helped you!!!

Step-by-step explanation:

For the average height of fhe boys:

[tex] \frac{5.4ft + 6.12ft + 7.02ft + 4.9ft + 6.25ft}{5} \\ = 5.938 \: ft[/tex]

In solving for the average height, we used addition and division operations.

Answer: k = 21

Step-by-step explanation:

3(7 + x) = 3x + k

21 + 3x = 3x + k

21 + 3x - 3x = 3x + k - 3x

k = 21

Step-by-step explanation:

Jimarcus plans to build a fence of 5 1/3 yards longs

He want to divide it into 2/3 yard sections

Therefore the number that will be produced can be calculated as follows

= 5 1/3 ÷ 2/3

= 16/3 ÷ 2/3

= 16/3 × 3/2

= 16/2

= 8

Answer:

x = 50.6 cm

Step-by-step explanation:

ΔMAB ≈ ΔNMP

set up a proportion:  MA / MN = MB / MP

MA = 46.2 - 14

MA = 32.2

32.2 / 46.2 = x / 72.6

cross-multiply:

46.2x = 2337.72

x = 50.6

Answer:

3:18

Step-by-step explanation:

From 3:12 PM to 5:12 PM it's 3 hours.

From 5:12 PM to 5:30 PM it's 18 minutes.

Total elapsed time: 3:18

I don't know why the question asks "what part of an hour" when the answer is more than 3 hours.

Answer:

763

Step-by-step explanation:

there are 763 more apple trees than pear trees

Step-by-step explanation:

so, first we write the words into equations.

8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P  which we can replace the numbers to get (872)-(109)=763 more trees

Answer:122.625

Step-by-step explanation:981 divided by 8 equals 122.625

Answer:

The right answer is D, "n" can be any value greater than 2

Step-by-step explanation:

If variable "n" was any value less than or equal to 2, then the inequality would be less than or equal to 16, which isn't valid. So "n" has to be any value greater than 2.

Answer:

Step-by-step explanation:

The reference line has a slope of -2. A perpendicular line will have a slope, m, that satisfies

-2m=-1, so it will have a slope of 1/2 then our line y=mx+b becomes

y=x/2+b, using point (-4,3) we have

3=-4/2+b

3=-2+b

b=5 so our line is

y=x/2+5 or more neatly

y=(x+10)/2

Answer:

the slope in line 1 is a

Answer:

B. 0.5

Step-by-step explanation:

There are 10 circles in total. 5 are shaded in.

We would make that a fraction.

5/10

Then we would convert it to a percent

50%

Then we will convert it to a decimal

0.5

Therefore, your answer would be B. 0.5

Answer:

1.3

Step-by-step explanation:

1. .65 = .5c ---> .65/.5

2. 1.3 = c

Answer:

1

Step-by-step explanation:

make all fraction have the same denominator:

7/10 - x + 15/10 = 12/10

isolate x: 12/10 - 7/10 - 15/10 ---> -x = -10/10

divide by 1 x = 10/10 or 1

x = 1

Answer:

1

Step-by-step explanation:

Let the no. be x

7/10-x+3/2=6/5

-x=6/5-3/2-7/10

-x=-10/10

-x=-1

x=1

The correct option is (C). No, because the sum of the probabilities is more than one.

In mathematics, a probability distribution is a function that expresses the likelihood of many possible values for a variable. Graphs and probability tables are common ways of displaying probability distributions.

In the given table, the probabilities are,

P(x) = 0.2, 0.3, 0.4, 0.1 and 0.05.

The sum of the probabilities = 0.2 + 0.3 + 0.4 + 0.1 + 0.05

                                                = 1.05

Since, the sum of the probabilities is more than one, therefore, the table does not represent the probability distribution.

Answer:6 ounce of cereal are left in  the box

Step-by-step explanation:

Total amount of cereal = 16 ounce

Amount of cereal eaten by Tina= 3/8 X16= 6ounce

Amount of cereal eaten by Lane= 1/4 X16= 4ounce

Amount of cereal left = Total amount of cereal -Amount of cereal eaten by Tina and Lane

=16- ( 6+4)
