Ann 's car can go 132 miles on 4 gallons of gas. During a drive last weekend, Ann used 5 gallons of gas. How far did she drive? Use pencil and paper. Explain how the problem changes if you were given the distance Ann drove last weekend instead of how much gas she used.
Answers
Answer:
Ann traveled 165 miles on 5 gallons of gas
Step-by-step explanation:
First we must know how many miles are in a gallon (in this situation). Last weekend Ann drove 132 miles with 4 gallons of gas, we can divide to find out how many miles she drove on 1 gallon. 132/4 = 33. This means Ann drove 33 miles on 1 gallon of gas. To get your answer, simply multiply 5 and 33. 5 times 33 = 165.

Night students :
n1 =30 x1= 3.34 s1 = 0.02
Day students:
n2 = 30 x2 = 3.32 s2 = 0.08
The test statistic :
(x1 - x2) / √(s1²/n1) + (s2²/n2)
T= (3.34 - 3.32) / √(0.02²/30) + (0.08²/30)
T = 0.02 / 0.0150554
Test statistic = 1.328
Using the conservative approach ;
df = Smaller of n1 - 1 or n2 - 1
df = 30 - 1 = 29
Pvalue(1.328, 29) = 0.097
At α = 0.10
Pvalue < α ; Hence, we reject H0 ; and conclude that there is significant evidence that GPA of night student is greater than GPA of day student
The graph of a quadratic function with vertex (-2,1) is shown in the figure below. Find the domain and the range.
Answers
The required expressions for the domains and ranges of the given graphs are;
The range of the quadratic function of a graph is [1, ∞)The domain of the quadratic function is (-∞, ∞)The reasons why the above values for the range and domain are correct are;
The given vertex of the quadratic equation = (-2, 1)
The vertex form of a quadratic equation is y = a·(x - h)² + k
A point on the graph is (-1, 4)
Therefore;
4 = a·((-1) - (-2))² + 1 = a + 1
a = 4 - 1 = 3
The equation of the graph is y = 3·(x + 2)² + 1
The domain and range expression having round brackets indicates that the adjacent values are not included. A square bracket means they are included.
The Range of the Function:The range of the of the function of the graph having the equation y = 3·(x + 2)² + 1, and from the graph is found as follows;
The minimum y- value = 1
The maximum y-value = ∞ (infinity)
The range of the graph is 1 ≤ y ≤ ∞, which gives;
The range of the quadratic function of the graph is [1, ∞)
The Domain of the Function:The graph of the function is U-shaped and the ends of the graph of the function extends to infinity on both sides
The domain of a function is the set of x-values that the function can have
From y = 3·(x + 2)² + 1, the possible x-values are -∞ < x < ∞
Therefore;
The domain of the quadratic function is (-∞, ∞)

3) Last year the mean salary for professors in a particular community college was $62,000 with a standard deviation of $2000. A new two year contract is negotiated. In the first year of the contract, each professor receives a $1500 raise.
Find the mean and standard deviation for the first year of the contract.
b) In the second year of the contract, each professor receives a 3% raise based on their salary during the first year of the contract. Find the mean and the standard deviation for the second year of the contract.
Answers
a) Mean for the first year of the contract: $63,500
The standard deviation for the first year of the contract: $2,000.
b) Mean for the second year of the contract: $65,405.
The standard deviation for the second year of the contract: $60.
We have,
To find the mean and standard deviation for the first year of the contract, we can use the given information and the properties of the normal distribution.
Given:
The mean salary for professors in the previous year = $62,000
Standard deviation in the previous year = $2,000
Raise in the first year = $1,500
Mean for the first year of the contract:
The mean salary for the first year can be obtained by adding the raise to the previous mean:
Mean = Previous Mean + Raise
Mean = $62,000 + $1,500
Mean = $63,500
The standard deviation for the first year of the contract:
Since each professor receives the same raise, the standard deviation remains the same:
Standard Deviation = $2,000
Therefore, for the first year of the contract, the mean salary is $63,500, and the standard deviation remains $2,000.
Now,
In the second year of the contract, each professor receives a 3% raise based on their salary during the first year of the contract.
To find the mean and standard deviation for the second year, we can use the given information and the properties of the normal distribution.
Mean for the second year of the contract:
To calculate the mean for the second year, we need to add a 3% raise to the mean salary of the first year:
Mean = Mean of the first year + (3% * Mean of the first year)
Mean = $63,500 + (0.03 * $63,500)
Mean = $63,500 + $1,905
Mean = $65,405
The standard deviation for the second year of the contract:
Since each professor receives a raise based on their salary from the first year, the standard deviation also increases. To calculate the standard deviation, we multiply the standard deviation from the first year by the percentage increase:
Standard Deviation = Standard Deviation of the first year * (Percentage Increase / 100)
Standard Deviation = $2,000 * (3 / 100)
Standard Deviation = $2,000 * 0.03
Standard Deviation = $60
Therefore, for the second year of the contract, the mean salary is $65,405, and the standard deviation is $60.
Thus,
a) Mean for the first year of the contract: $63,500
The standard deviation for the first year of the contract: $2,000.
b) Mean for the second year of the contract: $65,405.
The standard deviation for the second year of the contract: $60.

Answers
The scale factor of figure B to figure A is 1/2.
How to find the scale factor?To find the scale factor of figure B to figure A, we need to determine how much the corresponding sides of the two figures have been multiplied or divided by.
Looking at the figures, we can see that the corresponding sides of figure B are half the length of the corresponding sides of figure A. For example, the length of side AB in figure A is twice the length of side AB' in figure B, and the length of side BC in figure A is twice the length of side B'C' in figure B.
Since the corresponding sides of figure B are half the length of the corresponding sides of figure A, the scale factor of figure B to figure A is 1:2 or 1/2.

A bank account gathers compound interest at a rate of 5% each year.
Another bank account gathers the same amount of money in interest by the end of each year, but gathers compound interest each month.
If Haleema puts £3700 into the account which gathers interest each month, how much money would be in her account after 2 years and 11 months?
Give your answer in pounds to the nearest 1 p.
Answers
Haleema would have approximately £3947.46 in her account after 2 years and 11 months, considering the monthly compounding interest of 5%.
To calculate the amount of money in Haleema's account after 2 years and 11 months, we need to consider the monthly compounding interest on the account.
The interest rate is given as 5% per year, which means the monthly interest rate is (5%/12) = 0.4167%.
Let's calculate the final amount using the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.
In this case, P = £3700, r = 0.004167, n = 12 (monthly compounding), and t = 2.917 (2 years and 11 months).
Plugging these values into the formula, we get:
A = £3700(1 + 0.004167/12)^(12*2.917)
A ≈ £3947.46
The amount of money in Haleema's account after 2 years and 11 months would be approximately £3947.46.

Step-by-step explanation:
7(4+9)

7×13= 91
28 + 63 = 91
Both give the same answer
Answer:
The sum 28 + 63 can be expressed as 7 ( 4 + 9 )
Step-by-step explanation:
To solve the problem you need to be aware of the distributive property of multiplication. This property simply says that a multiple of a group of addens, aka the sum in the parenthesis, can be multiplied individually and summed.
The 7 infront of the parenthesis implies the multiplication operation on the grouping of the sum of 4 and 9.
You can rewrite it as such:
7 * ( 4 + 9 )
= 7 * 4 + 7 * 9
= 28 + 63
Note, how we simply used the multiplier 7 distributed to each term within the parenthesis to create our desired sum.
