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.

Trap spacing measurements (in meters) for a sample of seven teams of red spiny lobster fishermen are provided. Let represent the average of the trap spacing measurements for the population of red spiny lobster fishermen fishing in a particular region. The mean and standard deviation of the sample measurements were previously computed to be x=89.4, and s=11.4 meters respectively. Suppose the fishermen want to determine if the true value of differs from 95 meters

Help me please
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

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?
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

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

Examine the following table.
Does this table represent a probability distribution?
Explain your answer.
a. Yes, because the sum of the probabilites is less than one.
b. Yes, because the sum of the probabilities is more than one.
C. No, because the sum of the probabilities is more than one.
d. No, because the sum of the probabilities is less than one.
Answer:
the answer is c
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 distributionIn 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
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

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

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

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