A. -2.5
B. 0.0062
C. 0.9938
D. 2.5

Answers

Answer 1

Answer:

0.006

Step-by-step explanation:

We are actually looking for the area under the standard normal curve to the left of 50.  The proper distribution function on my old TI calculator is normalcdf(:

normalcdf(-1000,50,75, 10),

which returns 0.006   (Answer B)

i suck at slope

Answers

Answer:

m= -1/3

Step-by-step explanation:

to find the slope you have to go from any point on the line to a second point on the line.

for example go from point located at (-4, 2) to point (2,0)

slope = how much you moved vertical / how much you moved horizontal

look at the graph at (-4, 2)

move down 2 and then

move right 6 you should be at (2, 0)

which means that the slope m= -2/ 6 = -1/3

Maybe you can estimate it to 41.

answer:

a = 28 millimeters

step-by-step explanation:

since this is a right triangle, we can use the pythagorean theorem a^2 + b^2 = c^2

a^2 + 21^2 = 35^2

a^2 + 441 = 1225

a^2 = 784

Y=3

Answers

Answer:

y=2

Step-by-step explanation:

-2y+1=y-5

Add 2y to each side

-2y+2y+1=y+2y-5

1 = 3y -5

Add 5 to each side

1+5 = 3y-5+5

6 = 3y

Divide each side by 3

6/3 = 3y/3

2 =y

Answer:

y=2

Step-by-step explanation:

Move y to the other side by subtracting by y on both sides:

-y-2y+1=y-y-5

-3y+1=-5

Move the 1 to the other side by subtracting by 1 on both sides:

-3y+1-1=-5-1

-3y=-6

Divide -3 on both sides to eliminate the -3 on y

-3y/-3=-6/-3

The most Brendan can afford to pay per year in mortgage payments is $10,500, and his credit score is currently 544. According to the following table for a $150,000 mortgage, by how many points would he need to improve his credit score in order to take a mortgage for $150,000? FICO Interest Monthly Score Rate Payment 720-850 700-719 675-699 620-674 560-619 500-559 5.59% 5.71% 6.25% 7.40% 8.53% 9.29% $860 $872 $924 $1039 $1157 $1238 O A. 16 points B. 156 points C. 76 points D. 131 points​

Answers

Answer:

B. 156

Step-by-step explanation:

Brendan would need to improve his credit score by 75 points to qualify for a $150,000 mortgage with a monthly payment of $875 or less.

We have,

To determine Brendan's interest rate and monthly payment for a $150,000 mortgage, we need to find which range his FICO score falls in.

From the table, we see that his score of 544 falls in the range of 500-559, which corresponds to an interest rate of 9.29% and a monthly payment of $1238.

Next, we can use the mortgage payment of $10,500 per year to determine the maximum monthly payment Brendan can afford.

i.e

$10,500 per year / 12 months

= $875 per month

Since this amount is less than the monthly payment for the 500-559 FICO score range, Brendan would need to improve his credit score to qualify for a $150,000 mortgage.

To determine how many points he needs to improve, we can look at the next lowest interest rate and payment in the table, which corresponds to a FICO score range of 560-619.

The monthly payment for this range is $1157, which is below Brendan's maximum payment of $875.

So, he needs to improve his credit score to fall into this range.

To determine how many points he needs to improve,

we can subtract the minimum FICO score in the 560-619 range (560) from his current FICO score (544), and then add that difference to the maximum FICO score in the 560-619 range (619).

i.e

(619 - 560) + (560 - 544)

= 59 + 16

= 75

Therefore,

Brendan would need to improve his credit score by 75 points to qualify for a $150,000 mortgage with a monthly payment of $875 or less.

1,9,4,6,8,8 which is the median

Answers

Answer:  Median = 7

=======================================================

Explanation:

Sort the values from smallest to largest. Doing so leads to the list {1,4,6,8,8,9}

Since the set is small enough, you can probably notice that the middle most number is a tie between the 6 and the first 8. The midpoint is (6+8)/2 = 14/2 = 7.

The median is 7.

---------------

If you wanted, you could cross off the first and last items of the set

That means we go from {1,4,6,8,8,9} to {4,6,8,8}

Then repeat to get the smaller set {6,8}

This shows we have a tie between the 6 and 8 as the middle most item, and why 7 is the median (since 7 is the midpoint between 6 and 8).

Answers

Answer:

[tex]14 tan\theta = -48[/tex]

Step-by-step explanation:

[tex]cos \theta = \frac{-7}{25}\\\\cos^2 \theta = \frac{49}{625}\\\\sin^2 \theta = 1 - cos^2 \theta\\\\[/tex]

        [tex]=1 - \frac{49}{625}\\\\=\frac{625-49}{625}\\\\=\frac{576}{625}\\\\[/tex]

[tex]sin \theta = \sqrt{\frac{576}{625}} = \frac{24}{25}[/tex]

[tex]tan \theta = \frac{sin \theta}{cos \theta}[/tex]

Step-by-step explanation:

The volume was given as (11.13 cubic feet)

Length as (2.6 feet)

Width as(1.9 feet)

Volume of triangular prism can be written as ( length × width × height)

Volume= ( length × width × height)

Then substitute the values, we have

11.13 = 2.6 × 1.9 × height

Height= 11.13/(2.6×1.9)

= 11.13/4.94

= 2.25 feet
