What is the probability that a random sample of 12 second grade students from the city in a mean reading rate of more than 96 words per minute?
Complete Question
The reading speed of second grade students in a large city is approximately normal, with a mean of 90 words per minute (wpm) and a standard deviation of 10 wpm.
What is the probability that a random sample of 12 second grade students from the city in a mean reading rate of more than 96 words per minute?
Answer:
[tex]P(\=x >96 )=0.01884[/tex]
Step-by-step explanation:
From the question we are told that:
Sample size [tex]n=12[/tex]
Sample mean [tex]\=x =90[/tex]
Standard Deviation [tex]\sigma=10[/tex]
Generally
[tex]\sigma_x=\frac{\sigma}{\sqrt{10}}[/tex]
[tex]\sigma_x=\frac{10}{\sqrt{12}}[/tex]
[tex]\sigma_x=2.887[/tex]
Generally the equation for P(\=x >96 ) is mathematically given by
[tex]P(\=x >96 )=P(Z>\frac{\=x-\mu_x}{\sigma_x})[/tex]
[tex]P(\=x >96 )=P*(Z>\frac{90-96}{2.887})[/tex]
[tex]P(\=x >96 )=1-P(Z<2.08)[/tex]
[tex]P(\=x >96 )=1-0.98116[/tex]
[tex]P(\=x >96 )=0.01884[/tex]

What is value of x if 20x-10*110=50
Answer:
57.5
Step-by-step explanation:
20x - (10 x 110) = 50
=> 20x - 1100 = 50
=> 20x = 1150
=> x = 1150/20
=> x = 115/2
=> x = 57.5

The graph shows the production of cars per day at a factory during a certain period of time. What is the domain of this function during this period? (1 point)
The domain is all real numbers o through 9.
The domain is all integers o through 9.
The domain is positive real numbers.
The domain is all positive integers.
Answer:
B. domain is all integers 0 through 9
Step-by-step explanation:
Domain values area usually plotted along the horizontal axis. In this case, the number of days is the domain of the of the function.
The domain of the function that is plotted on the graph ranges from 0, 1, 2 to 9.
1, 2, 3 to 9 are all integers. Therefore, we can conclude that the "domain is all integers 0 through 9."

The dimensions of a garden are 300' by 200'. If a model garden with the
scale of 10' = 1" is to be made, find the dimensions of the model.
A.) 3" by 1"
B.) 30" by 20"
C.) 45" by 10"
D.) 60" by 20"
Answer:
B
Step-by-step explanation:
We know that 10' = 1". We want to find a x and y for 300' = x" and 200' = y". We can do this by figuring out ratios between similar values. For the numbers ending in ', we can say that 300/10 = 30 and 200/10 = 20. Therefore, to get x and y, we can multiply
10' = 1" by 30 on both sides to get
300' = 30"
and multiply by 20 on both sides to get
200' = 20"
Therefore, we can say that 300' by 200' = 30" by 20"

On a job application, Doris gave her age as 32 years. Her actual age at the time was about 27.What is the relative error for her age?
Answer:
18.52%
Step-by-step explanation:
Relative error can be described as the ratio of the measured absolute value to the actual value
relative error = (stated age - actual age) / actual age x 100
(32 - 27) / 27 x 100
5 / 27 x 100 = 18.52%

4 carts weigh 20 lbs. each.
How much work was done?
_____________ ft.-lbs. (total work)
Answer:
10 x 15
Step-by-step explanation:
beam
The total work done is 1800 ft- lbs.
What is Work Done?It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.
Work is accomplished when we push a block with some force; the body moves more quickly. Work completed is noted as.
We have,
2 carts weigh 50 lbs. each.
4 carts weigh 20 lbs. each.
So, 2 carts weigh = 50 x 2 = 100 lbs
and, 4 carts weigh = 20 x 4 = 80
Then, work done = (100 + 80) x 10
= 1800 ft- lbs

Your cellphone plan is by the minute. Each minute of use costs $0.10. Create a relation that represents the amount spent, A, per minute, m, of call time. Then, use the relation to find the amount spent if you talk 65 minutes. Show your work.
Answer:
A = 0.1m
A = $6.5
Step-by-step explanation:
We are told that each minute of use costs $0.10.
If the minutes spent is represented by "m" and amount spent is "A', then the relation for amount spent is;
A = 0.1m
If he talked for 65 minutes, then we have;
A = 0.1 × 65
A = $6.5

Answer:
A.) 6.4 units
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of AB.
If we find the horizontal and vertical distance of A and B, we form a triangle, with leg lengths of 5 and 4.
Now, we just solve using the Pythagorean theorem.
5^2 = 25
4^2 = 16
25 + 16 = 41
sqrt 41 ≈ 6.4 units.

Diego's family truck holds 21 gallons of fuel. Each day the car uses 1.5 gallons of fuel. A warning light comes on when the remaining fuel is 2.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 10 days without the warning light coming on? Explain or show your reasoning. Starting from a full tank, can Diego's family drive the car for 15 days without the warning light coming on? Explain or show your reasoning. Diego says the expression 21 - 1.5t helps him understand this situation. In this situation, what does this expression represent, and what does the variable t stand for? Write and solve an equation to determine the number of days Diego's father can drive the car without the warning light coming on. Write and solve an inequality that represents the number of days driven without the warning light coming on. Explain clearly what the solution to the inequality means in the context of this situation
Answer:
The inequality is 0.6x < 12.5
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days
Step-by-step explanation:
14 gallons-1.5 gallons=12.5 gallons
we know that
If the remaining fuel is greater than 1.5 gallons Diego's father can drive the car without the warning light coming on
so
Let
x ----> the number of days
0.6x < 12.5 inequality that represent the situation
Solve for x
x < 12.5/0.6
x < 20.8 days
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

as part of a weight loss plan, Levi's average calories consumed per day, denoted by c, subject to a maximum of 15 calories, is measured to calculate the amount of weight he will lose. if he is losing weight consistently, what is the domain of the function
Answer:
The domain is;
0 < c ≤ 15
Step-by-step explanation:
We are told that Levi's average calories consumed per day is denoted by c.
Now, we are told it is subject to a maximum of 15 calories.
Thus; c ≤ 15
Now,if he is losing weight consistently, then c must be greater than 0.
Thus,the domain is;
0 < c ≤ 15

Belinda is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for three years:
Number of years 1 2 3
House 1 (value in dollars) 186,160 193,606.40 201,350.66
House 2 (value in dollars) 190,000 201,000 212,000
Part A: What type of function, linear or exponential, can be used to describe the value of each of the houses after a fixed number of years? Explain your answer. (2 points)
Part B: Write one function for each house to describe the value of the house f(x), in dollars, after x years. (4 points)
Part C: Belinda wants to purchase a house that would have the greatest value in 30 years. Will there be any significant difference in the value of either house after 30 years? Explain your answer, and show the value of each house after 30 years. (4 points)
In this question, two houses have an initial value of $179,000, and the projected values are given in the tables for houses 1 and 2.
Part a:
If the absolute value of the change is always the same, it is linear.
If the rate is the same, it is exponential.
House 1:
We have that:
193,606.4 - 186,160 = 7446.4
201,350.66 - 193,606.40 = 7744.26
Let's try exponential:
[tex]\frac{193,606.4}{186,160} = 1.04[/tex]
[tex]\frac{201,350.66}{193,606.40} = 1.04[/tex]
For house 1, the rate of change is the same, and thus, it is exponential.
House 2:
212,000 - 201,000 = 201,000 - 190,000 = 11,000.
Absolute value of change is the same, so linear.
Thus, for house 1, an exponential function is used, as the rate of change is the same, and for house 2, as the absolute value of change is always the same, it is linear.
Part B
House a:
Exponential function, with initial value of $179,000, and exponential growth rate of 1.04 - 1 = 0.04. Thus:
[tex]f_a(x) = 179000(1+0.04)^x[/tex]
[tex]f_a(x) = 179000(1.04)^x[/tex]
House b:
Linear function, with initial value of $179,000, increasing by $11,000 each year. So
[tex]f_b(x) = 179000 + 11000x[/tex]
Part c:
House a after 30 years:
[tex]f_a(30) = 179000(1.04)^30 = 580,568[/tex]
House b after 30 years:
[tex]f_b(30) = 179000 + 110000(30) = 509,000[/tex]
In 30 years, house a will have a value of $580,568, while house b will have a value of $580,568. House a will have a higher value, due to exponential growth.
