Answer 1

Answer:

48 cm^2

Step-by-step explanation:

We can substitute the h in the given equation with 8.

1/2 * (8+4) * 8

Next we can add inside the parenthesis

1/2* (12) * 8

Another way we can write 1/2* 12 is 12 divided by 2 which is equivalent to 6.

So, now our equation is 6*8

6*8 = 48 so our answer is 48 cm^2

Hope this Helps!!! :)

What is her monthly payment?

How much will she pay back in total?

What is the finance charge?

Answers

Answer:

Step-by-step explanation:

Given data

principal=$7500

rate= 3.875%= 0.03875

time =6years

The expression for the final amount for a simple interest is

A=p(1+rt)

A=7500(1+0.03875*6)

A=7500(1+0.2325)

A=7500(1.2325)

A=9243.75

$19243.75

1. What is her monthly payment?

given that it is spread over 6 years

there are 12*6 months= 72months

monthly pay=9243.75/72= $128.38

2. How much will she pay back in total?

=$19243.75

3. What is the finance charge?

the finance charge is the interest which is

$19243.75-$7500=$11743.75

Lorena borrowed $1950 to buy books and a tablet for her freshman year of college. She will pay off the loan in 10 months at an annual simple interest rate of 5.75%. How much interest will she be charged and what is the total amount she must pay at the end of the 10 months? Round your answer to the nearest cent.

Answers

Answer:

Step-by-step explanation:

Simple Interest = Principal * Rate * Time/100

Given

Principal (amount borrowed) = $1950

Rate = 5.75%

Time = 10month

Convert time to year

To do that, we will divide the value in months by 12 i.e Time = 10/12

Time = 5/6 years

Substitute into the formula and find the simple interest

SI = (1950 * 5.75*5/6)/100

SI = (1950 * 5.75*5)/600

SI = 56,062.5/600

SI = $93.4375

Hence she will be charged interest of $93.4375

To get the total amount after 10 months, we will use the formula;

Amount = Principal + Interest

Amount = $1950 + $93.4375

Amount = 2,043.4375

Hence she must pay back $2,043.4375 after 10 months

over a long time, cable from acme cable co has a mean strength of 37.5 ksi with a known population standard deviation of 1 ksi. find the probability that a random piece of th ecable has a strength x lower than 36.0 ksi

Answers

Answer:

The value is

 [tex]P(X < 36) = 0.066807[/tex]

Step-by-step explanation:

From the question we are told that

 The mean is  [tex]\mu = 37.5 \ ksi[/tex]

   The standard deviation is  [tex]\sigma = 1 \ ksi[/tex]

   

Generally the probability that a random piece of the cable has a strength x lower than 36.0 ksi is mathematically represented as

     [tex]P(X < 36) = P(\frac{X - \mu}{ \sigma } < \frac{ 36 - 37.5}{1} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

    [tex]P(X < 36) = P(Z < -1.5 )[/tex]

From the z table the probability of  [tex](Z < -1.5)[/tex] is  

     [tex]P(Z < -1.5) = 0.066807[/tex]

So

     [tex]P(X < 36) = 0.066807[/tex]

How to Solve X-3/8= 7/16

Answers

Answer:

x=13/16

Step-by-step explanation:

The question is asking us to isolate the variable x. This means that we need to add -3/8 to both sides of the equation. Because the denominators of the fractions 3/8 and 7/16 are not the same, we need to find a common denominator, which is 16. (So we change 3/8 to 6/16 because the two fractions are equal). Now that we have the fractions 6/16 and 7/16 we can add the two to get x=13/16

Put the following equation of a line into slope-intercept form
2x - 2y = 6

Answers

Answer:

Y=-2x+3

Step-by-step explanation:

2x-2y=6

2y=-2×+6

y=-2×+6/2

y=-2x+3

The equation of a line into slope-intercept form is y = x - 3

The standard form of an equation in slope-intercept form is expressed using the equation y = mx + b

m is the slope of the line

b is the y-intecept

Given the equation 2x - 2y = 6

Divide through by 2

x - y = 3

-y = -x + 3

Multiply through by -1

-(-y) = -(-x) + (-3)

y = x - 3

Hence the equation of a line into slope-intercept form is y = x - 3

Answers

Answer:

a. His flag ended up with base angles of 86° and 62°. so the stick was 12° out of alignment from the correct position (both angles

74°).

Step-by-step explanation:

First, let's calculate the measures of the base of the angles Neko ended up with.

The measure of the angle adjacent to the exterior angle = 180° - 118° = 62°

The measure of the other base = 180° - (62° + 32°) = 180° - 94° = 86°

So, Neko ended up with 86° and 62°.

To make a flag that is in the form of an isosceles ∆, it means the measure of the two bases most be equal to each other.

Since he measures the tip of the flag to be 32°, the measure of the remaining two equal bases ought to be (180 - 32)/2 = 148/2 = 74° each.

The difference between 74° and what he ended up with = 86 - 74 = 12°.

74 - 62 = 12°.

Therefore, the stick was 12° out of alignment.

The population standard deviation for the heights of dogs, in inches, in a city is 7.5 inches. If we want to be 90% confident that the sample mean is within 2 inches of the true population mean, what is the minimum sample size that can be taken

Step-by-step explanation:

Formula of sample size :

[tex]n=(\dfrac{z^c\times\sigma}{E})^2[/tex] , where [tex]z^c[/tex] = critical z-value for confidence level , [tex]\sigma[/tex] = population standard deviation , E = margin of error.

[tex]\Rightarrow\ n=(\dfrac{1.645\times7.5}{2})^2\\\\\Rightarrow\ n=(6.16875)^2=38.05347\approx39[/tex]

Answer:

9

Step-by-step explanation:

Answer:

9 ounces

Step-by-step explanation:

In this equation, we are given two things. We know how much each disc weighs (.9 ounces) and we know how many discs Danny bought (10 discs).

To figure out how much the discs weigh, we must do the following steps:

We first step up the equation: 10 discs times .9 ounces

Then, we multiply the numbers to get our final answer: 10(.9 ounces)= 9 ounces

The 10 discs weigh a total of 9 ounces.

What is the probability a server will refuse to serve alcoholic beverages to exactly 2 minors if he randomly checks the IDs of 5 of the 9 students in the establishment, and 4 of the 9 students are minors?

Answers

Answer:

10/21

Step-by-step explanation:

Probability = Expected outcome/total outcome

If he randomly checks the IDs of 5 of the 9 students in the establishment, the total outcome will be expressed as:

9C5 = 9!/4!5!

9C5 = 9×8×7×6×5!/5!×24

9C5 = 9×8×7×6/24

9C5 = 126

Total outcome = 126

For the expected

First we know that 4out of 9 students are minor, and we want to know the probability that exactly 2 are minor, this can be done in 4C2 ways

4C2 = 4!/2!2!

4C2 = 4×3×2/4

4C2 = 6

Also since 4 out of 9 are minor, then 5 are not minor and if out of every 5, exactly two are minor, then 3 are not.

Those not minor can be expressed in 5C3 ways

5C3 = 5!/2!3!

5C3 = 5×4×3!/2×3!

5C3 = 20/2

5C3 = 10

Total expected outcome = 4C2 × 5C3

Total expected outcome= 6×10 = 60

Hence, the probability a server will refuse to serve alcoholic beverages to exactly 2 minors will be;

= 60/126

= 30/63

= 10/21
