In some 4.0 grading systems, a student's grade point average (GPA) is calculated by assigning letter grades the following numerical values.
A = 4.00 B− = 2.67 D+ = 1.33
A− = 3.67 C+ = 2.33 D = 1.00
B+ = 3.33 C = 2.00 D− = 0.67
B = 3.00 C− = 1.67 F = 0.00
Use this grading system to find this student's GPA. Round to the nearest hundredth.

Answer:
This student's GPA is 3.04.
Step-by-step explanation:
Student's GPA:
To find the students GPA, we find the sum of the multiplication of each numerical grade(A is 4, A- is 3.67 and so on) and the credit load of the course, divided by the number of courses.
His grades are:
4 in English worth 3 credits.
4 in Antropology worth 3 credits.
2.67 in Chemistry worth 4 credits.
2 in French worth 4 credits.
3 in Theatre worth 2 credits.
GPA:
[tex]\frac{4*3+4*3+2.67*4+2*4+3*2}{3+3+4+4+2} = 3.04[/tex]
This student's GPA is 3.04.

Write the equation in standard form for thelcircle with center (-8, -1) and radius 4
9514 1404 393
Answer:
(x +8)^2 +(y +1)^2 = 16
Step-by-step explanation:
The standard form equation for a circle with center (h, k) and radius r is ...
(x -h)^2 + (y -k)^2 = r^2
For your center and radius, the equation is ...
(x -(-8))^2 +(y -(-1))^2 = 4^2
(x +8)^2 +(y +1)^2 = 16
Solve the systems of equations by using the substitution method,show your work.
3x - 8y = -50
6y = x

Answer:
0.60 more
Step-by-step explanation:
Sandwich: 1.25
Milkshake: 0.65
We need to find the difference between the 2
1.25 - 0.65 = 0.6
A sandwich costs 60 cents MORE than a milkshake

On Monday, 248 students went on a trip to the zoo. All 6 buses were filled and 8 students had to travel in cars. How many students were in each bus?
Answer:
40 students in each bus.
Step-by-step explanation:
Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.
248-8=240
240/6=40
40 students in each bus.

1 Write the series 3 + 6x +9x2 +12x + ... with 45 terms in sigma notation.
Answer:
Step-by-step explanation:
It looks like every time the coefficient increases by 3 while the exponent increases by 1.
[tex]\\45\\\sum 3(n+1)x^{n}\\n = 0[/tex]
Notice it starts at zero so 3 is multiplied by (x+1) to make it start from 0
The exponent is simply n, because at the start is it zero [tex]x^0=1[/tex], then 1, then 2, so on.
The upper limit is 45 because 45 - 0 = 45 terms
A taxi driver provides service in two zones of a city. Fares picked up in zone A will have destinations in zone A with a probability of 0.6 or in zone B with a probability of 0.4. Fares picked up in zone B will have destinations in zone A with a probability of 0.3 or in zone B with a probability of 0.7. The driver's expected profit for a trip entirely in zone A is 6; for a trip entirely in zone B is 8, and for a trip that involves both zones is 12. Find the taxi driver's average profit per trip.
Answer:
The taxi driver's average profit per trip is 4.4.
Step-by-step explanation:
Probability of fares picked up in zone A with destinations in zone A = 0.6
Probability of fares picked up in zone A with destinations in zone B = 0.4
Probability of fares picked up in zone B with destinations in zone A = 0.3
Probability of fares picked up in zone B with destinations in zone B = 0.7
The driver's expected profit for a trip entirely in zone A = 6
The driver's expected profit for a trip entirely in zone B = 8
The driver's expected profit for a trip involving both zones is 12
The taxi driver's average profit per trip:
zone A with destinations in zone A = 0.6 * 6 = 3.6
zone A with destinations in zone B = 0.4 * 12 = 4.8
zone B with destinations in zone A = 0.3 * 12 = 3.6
zone B with destinations in zone B = 0.7 * 8 = 5.6
Total profit expected for 4 trips = 17.6
Average profit per trip = 4.4 (17.6/4)

Given a standardized normal distribution (with a mean of O and a standard deviation of 1), determine the following probabilities.
a. P(Z > 1.09) b. P(Z < -0.22) c. P(-1.96
d. What is the value of Z if only 8.08% of all possible Z-values are larger?
Answer:
a) P(Z > 1.09) = 0.1379
b) P(Z < -0.22) = 0.4129.
c) P(Z < -1.96) = 0.025, P(Z > -1.96) = 0.025
d) Z = 1.4
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. P(Z > 1.09)
This is 1 subtracted by the pvalue of Z = 1.09.
Z = 1.09 has a pvalue of 0.8621
1 - 0.8621 = 0.1379, so
P(Z > 1.09) = 0.1379
b. P(Z < -0.22)
This is the pvalue of Z = -0.22.
Z = -0.22 has a pvalue of 0.4129. So
P(Z < -0.22) = 0.4129.
c) P(Z < -1.96) or P(Z > -1.96)
Z = -1.96 has a pvalue of 0.025. So
1 - 0.025 = 0.975
P(Z < -1.96) = 0.025
P(Z > -1.96) = 0.025
d. What is the value of Z if only 8.08% of all possible Z-values are larger?
Z with a pvalue of 100 - 8.08 = 91.92 = 0.9192, so Z = 1.4

In how many ways can 5 people arrange themselves in a row for picture taking ?
Answer:
120 times
Step-by-step explanation:
There are 5 people to fill the first place, 4 remaining to fill the second, 3 remaining to fill the third, 2 remaining to the fourth place and only 1 remaining to fill the fifth. That means there are 5 factorial (5!) ways. 5! = 5 x 4 x 3 x 2 x 1 = 120.

Amir subtracted a quantity from the polynomial 3x² + 8x - 16 and produced the expression x^2- 4. What quantity did Amir subtract? Explain how
you got your answer.
Answer:
[tex]2x^2+ 8x -12[/tex]
Step-by-step explanation:
Given
[tex]P = 3x^2 + 8x - 16[/tex]
[tex]Result = x^2 - 4[/tex]
Required
The quantity subtracted
Let the subtracted quantity be Q. So, we have:
[tex]P - Q = Result[/tex]
[tex]3x^2 + 8x - 16 - Q = x^2 - 4[/tex]
Collect like terms
[tex]Q = 3x^2 - x^2+ 8x - 16 + 4[/tex]
[tex]Q = 2x^2+ 8x -12[/tex]
The quantity subtracted is: [tex]2x^2+ 8x -12[/tex]
3) -5
A) quintic monomial
B) constant trinomial
C) constant monomial
D) quadratic monomial
Answer:
Constant monomial
Step-by-step explanation:
Monomial means that there is only one term, so constant trinomial cannot be correct.
Quintic monomials have a degree of 5 and quadratic monomials have a degree of 4, but this has a degree of zero, so this must be a constant monomial.
I hope this helps you. Have a nice day.
On the first two downs, a football team lost 15 yards and then lost 19 yards. Write an expression with addition that shows the changes in yards on the first two downs.
Answer:
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34
Step-by-step explanation:
At the first down, the net yardage of the football team was of 0.
After the first play:
Lost 15 yards, so the change in yards is:
0 - 15 = -15
After the second play:
Lost 19 yards, so the change in yards is:
-15 - 19 = -(15 + 19) = -34
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34
The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the lengths of the three sides of the triangle. Enter an exact answer. Do not type your answers as fractions or decimals.
a^2 + b^2 = c^2
Let c = hypotenuse = 2x
One of the legs = x. Let a or b = x.
I will let a = x. We can then say that b = 3.
3^2 + x^2 = (2x)^2
9 + x^2 = 4x^2
9 = 4x^2 - x^2
9 = 2x^2
9/2 = x^2
sqrt{9/2} = sqrt{x^2}
3/sqrt{2} = x
Rational denominator.
[3•sqrt{2}]/2 = x = a
Side 3 is given to be 3 feet. So, b = 3.
Hypotenuse = 2x
Hypotenuse = 2([3•sqrt{2}]/2)
Hypotenuse = 3•sqrt{2}
Understand?
The three sides are 3, [3•sqrt{2}]/2 and
3•sqrt{2}.
