A student earned grades of​ B, B,​ A, C, and D. Those courses had these corresponding numbers of credit​ hours: 4,​ 5, 1,​ 5, 4.

The grading system assigns quality points to letter grades as​ follows: A equals =​4, B equals =​3, C equals =​2, D equals =​1, and F equals =0. Compute the grade point average​ (GPA) and round the result to two decimal places.
a. 3.15
b. 1.41
c. 8.20
d. 2.41

Answer:

option D

Step-by-step explanation:

given,

grade earned = B, B,​ A, C, and D

credit​ hours:   4,​ 5, 1,​ 5, 4

A = 4,   B = 3,  C = 2,  D = 1   F = 0

grade point average​ (GPA) = ?

       = \dfrac{4\times B+5\times B+1\times A+5\times C+4\times D}{4+5+1+5+4}

       = \dfrac{4\times 3+5\times 3+1\times 4+5\times 2+4\times 1}{19}

       = \dfrac{45}{19}

       = 2.36

so, the near option is 2.41

Hence,  the correct answer is option D

Studies have suggusted that twins, in their early years, tend to have lower IQs and pick up language more slowly than non-twins.
Anna007 [38]

Answer:

Confidence interval: (21.9, 32.9).

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 26 - 1 = 25

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 25 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.98}{2} = 0.99. So we have T = 2.485

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2.485\frac{11.2}{\sqrt{26}} = 5.5

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 27.4 - 5.5 = 21.9 hours

The upper end of the interval is the sample mean added to M. So it is 27.4 + 5.5 = 32.9 hours

Confidence interval: (21.9, 32.9).

Find the measure of <C in the following figure: ​
Yuki888 [10]

Answer:

angle C =160 degree

Step-by-step explanation:

since the given triangle is an isosceles triangle their base angles must be equal. So,

x - 10 =x/2

2(x - 10) =x

2x - 20 = x

2x - x = 20

x = 20

for angle B

x - 10

20 - 10

10 degree

for angle A

x/2

20/2

10

For angle c

angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)

10 + 10 + angle C =180

20 + angle C =180

angle C =180 - 20

angle C =160 degree

For the following pairs of equations explain why the equations are NOT equivalent.
Serga [27]
If you were to make both x's equivalent, you'd have to multiply the first equation by 2 to get rid of the coefficient, 1/2. However, you'd have to multiply 2 onto -8 as well, therefore the equation would turn into x - 16 = 18. That is not equivalent to x - 8 = 18.
