The table shows how far a distance runner has traveled since the race began. what is her average rate of change, in miles per hour, during the interval 0.75 to 1.00 hours?

Answers

Answer 1

The average rate of change will be 5 miles per hour from 0.75 to 1 hour.

The average rate of change is the ratio of change in the y-value or the function value by the change in the x-value.

So according to the question,

the interval between 0.75 to 1 hour is =1-0.75=0.25 hour.

At 0.75 hours elapsed, the distance traveled is 3.5 miles

at 1 hour elapsed, the distance traveled is 4.75miles.

during the interval, 0.75 hours to 1-hour distance travelled=4.75-3.5=1.25 miles.

the average rate of change will be = change in distance traveled during the interval/interval time.

=(4.75-3.5)/(1-0.75)=1.25/0.25=5 miles per hour

Therefore the average rate of change will be 5 miles per hour from 0.75 to 1 hour.

Step-by-step explanation:

edge 2020

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

What is probability distribution

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.

An orchand has 8 times more apple trees than pear trees. There are 981 trees in all. How many more apple trees are there

Answers

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


Write an equation of a line perpendicular to x = -7 and passes through the
point (4,9).

Answers

Answer:

y = 9

Step-by-step explanation:

The line x = -7 is a vertical line, so the perpendicular line will be horizontal.

Horizontal lines have a slope of 0.

Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation

y = mx + b

9 = 0(4) + b

9 = b

Plug this and the slope into the equation:

y = mx + b

y = 0x + b

y = 9

So, y = 9 is the equation

Tina and Lane share a 16-ounce box of cereal. By the end of the week, Tina has eaten 3/8 of the box, and Lane has eaten 1/4 of the box of cereal. How many ounces are left in the box?

Answers

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)

16-10

= 6 ounce of cereal remaining

write an equation for a line perpendicular to y=-2x+1 and passing through the point (-4,3)

Answers

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
