Ruben made 3.4 gallons of peach ice cream in his new ice cream maker. If there are 22.5 servings in a gallon, how many servings of ice cream did Ruben make? Ruben made servings of ice cream.
Answer:
Reuben made 76.5 servings of Peach ice cream
Step-by-step explanation:
Total gallons of peach ice cream made = 3.4 gallons
Number of servings per gallon = 22.5
This means that:
1 gallon = 22.5 servings
∴ 3.4 gallons = 22.5 × 3.4 = 76.5 servings
Therefore, Reuben made 76.5 servings of Peach ice cream
Many states assess the skills of their students in various grades. One program that is available for this purpose is the National Assessment of Educational Progress (NAEP). One of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In a recent year, the national mean score was 289 and the standard deviation was 37. Assume that these scores are approximately Normally distributed, N(289, 37). How high a score is needed to be in the top 25% of students who take this exam (use technology)?
Answer:
A score of 314 is needed to be in the top 25% of students who take this exam.
Step-by-step explanation:
We are given that one of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In recent years, the national mean score was 289 and the standard deviation was 37.
Let X = scores of the tests provided by the NAEP
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = national mean score = 289
[tex]\sigma[/tex] = standard deviation = 37
Now, we have to find how high a score is needed to be in the top 25% of students who take this exam, that means;
P(X > x) = 0.25 {where x is the required score}
P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-289}{37}[/tex] ) = 0.25
P(Z > [tex]\frac{x-289}{37}[/tex] ) = 0.25
In the z table, the critial value of z that represents the top 25% of the area is given as 0.6745, that is;
[tex]\frac{x-289}{37}=0.6745[/tex]
[tex]{x-289}=0.6745\times 37[/tex]
x = 289 + 24.96 = 313.96 ≈ 314
Hence, a score of 314 is needed to be in the top 25% of students who take this exam.
Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total more than 3.
Answer:
1/2, or 50%
Step-by-step explanation:
1 Dice has 6 possible outcomes, rolled twice equal 12 "different" outcomes, since there are 3 numbers that are 3 or below, and 3 numbers about 3, then the change of getting a number above three is 1 in 2.
What value of g makes the equation true? –11 –3 3 11
Answer:
3
Step-by-step explanation:
(x + 7)(x - 4)
= x · x + x · (-4) + 7 · x + 7 · (-4)
= x² - 4x + 7x - 28
= x² + 3x - 28
Hence, g = 3.

What are the x-intercepts of the graph of the function f(x) = x^2 + 4x – 12?
(-6,0). (2.0)
(2. -16). (0, -12)
(-6.0), (2, -16), (2, 0)
(0.-12).(-6, 0), (2, 0)
Answer:
(- 6, 0 ) , (2, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² + 4x - 12 = 0 ← in standard form
(x + 6)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are (- 6, 0 ), (2, 0 )

26-4s=9s solve the equation
Answer:
26=9s+4s
13s=26
s=26/13
s=2
Step-by-step explanation:
hope it is helpful for you if it is follow me
Answer:
s=2
Step-by-step explanation:
We are given the equation:
[tex]26-4s=9s[/tex]
and asked to solve. We want to find out what the unknown variable, s, is. Therefore, we must isolate s on one side of the equation.
First, let's get all the terms with s on one side of the equation. 4s is being subtracted from 26. The inverse of subtraction is addition. Add 4s to both sides of the equation.
[tex]26-4s+4s=9s+4s[/tex]
[tex]26=9s+4s[/tex]
[tex]26=13s[/tex]
s is being multiplied by 13. The inverse of multiplication is division. Divide both sides of the equation by 13.
[tex]26/13=13s/13[/tex]
[tex]26/13=s[/tex]
[tex]2=s[/tex]
[tex]s=2[/tex]
Let's check our solution. Plug 2 in for s and solve.
26-4s=9s
26-4(2)=9(2)
26-8=18
18=18
This checks out, so we know our solution is correct.
The solution to the equation 26-4s=9s is s=2.
Which of the following employees has the greatest total employee compensation? a. Employee A: total job benefits $68,100 and total job expenses $100
b. Employee B: total job benefits $68,400 and total job expenses $300

The best or greatest total employee compensation will be Employee B: total job benefits $68,400 and total job expenses $300 so option (B) will be correct.
What are subtraction and summation?Subtraction is the minus of any two numbers generally it gives a lower value than the digits which are going to be in the substrate.
A summation, which is the result of adding two or more numbers or quantities, is also known as a sum. A summation always has an integer number of terms. There might simply be two terms, but there might also be 100,000 or a million. Summations exist with an infinite number of parameters.
Given that
In option (B) job benifits $68,400 and job expenses $300 hence the remaining amount = $68,400 - $300 = $68100 which is greatest among all option
In option (A) the job beneifits $68,100 and job expenses $100 hence the remaining amount = $68,100 - $100 = $68000 which is less than A and in all option it is less

3 lines are shown. A line with points A, F, D intersects a line with points B, F, E at point F. A line extends from point F to point C in between angle B F D. Which angle is a vertical angle with AngleEFD? AngleDFB AngleCED AngleBFC AngleAFB
Answer:
AngleAFB
Step-by-step explanation:
We know that vertical angles are angles that opposite each other when two lines intersect. They share a common point or vertex.
In the question, the angle opposite to angle EFD is angle AFB. This is because they share a common vertex.
Since they share a common vertex and are opposite to each other, angle AFB is the angle vertical to angle EFD.
So, the angle vertical to angle EFD is angle AFB.
Answer:
angle afb

(b) If you put $9050 in the ATM each day, what percent of the days in a month should
you expect to run out of cash?
Answer:
23.33%
Step-by-step explanation:
The computation of the percentage of days in a month for running out of cash is shown below:
Percentage of running out of Cash is
= (Relevant Occurrence of an event ÷ Total number of events) × 100%
where,
The Relevant occurrence of an event is 7 (105,94,101,98,94,96,92)
And, the total number of events is 30 i.e. 30 days
So, the percentage is
= 7 ÷ 30 × 100
= 23.33%

Determine how many solutions the equation has. If one solution, state the value of x. 4(x – 3) = 2x + 2x – 6 – 6
Answer:
infinite solutions
Step-by-step explanation:
Given
4(x - 3) = 2x + 2x - 6 - 6 ← distribute left side and simplify
4x - 12 = 4x - 12
Since both sides are equal then the equation has an infinite number of solutions.

by which when 625 is divided , will make the quotient a perfect cube
Answer:
[tex]\boxed{\bold{\huge{\boxed{5}}}}[/tex]
Step-by-step explanation:
625 when divided by 5 gives 125 which is a perfect cube.
=> [tex]\sf \frac{625 }{5 } = 125[/tex]
[tex]\rule[225]{225}{2}[/tex]
[tex]\sf \ \sqrt[3]{125} = 5[/tex]
So, 5 needs to be divided by 625 to make the quotient a perfect cube!
