Answer:

1. 100 - 12y = 16

2. b * (15 + 37) = 156

3. 27 + 12z = 87

4. 135/(5c) = 3

5. w^2 * (12/4) = 300

6. 12d / (25-19) = 4

7. 5x + 13 = 68

Step-by-step explanation:

1.

The product of y and 12 is "12y", so the difference of 100 and this product is "100 - 12y". The value of y is 7, so we have:

100 - 12*7 = 100 - 84 = 16

2.

The sum of 15 and 37 is "15 + 37", and b times this sum is "b * (15 + 37)"

b is equal to 3, so we have:

3 * (15 + 37) = 3 * 52 = 156

3.

The product of z and 12 is "12z", so 27 added to this product is "27 + 12z". The value of z is 5, so we have:

27 + 12*5 = 27 + 60 = 87

4.

The product of c and 5 is "5c", so 135 divided by this product is "135/(5c)". The value of c is 9, so we have:

135/(5*9) = 135 / 45 = 3

5.

The quotient of 12 and 4 is "12/4", so w to the second power times this quotient is "w^2 * (12/4)"

The value of w is 10, so we have:

10^2 * (12/4) = 100 * 3 = 300

6.

The difference of 25 and 19 is "25 - 19", so 12 times d divided by this difference is "12 * d / (25-19)"

The value of d is 2, so we have:

12 * 2 / (25-19) = 24 / 6 = 4

7.

The product of x and 5 is "5x", so this product added to 13 is "5x + 13"

The value of x is 11, so we have:

5*11 + 13 = 55 + 13 = 68

The value of probability P (A or B) is,

⇒ P (A or B) = 45

We have to given that;

To find the probability that either event will occur.

Now, By given figure we get;

P (A) = 25 + 5

P (A) = 30

P (B) = 5 + 15

P (B) = 20

P (A and B) = 5

Since, The formula is,

⇒ P (A or B) = P (A) + P (B) - P (A and B)

Substitute all the values we get;

⇒ P (A or B) = 30 + 20 - 5

⇒ P (A or B) = 50 - 5

⇒ P (A or B) = 45

Therefore, The value of probability P (A or B) is,

⇒ P (A or B) = 45

The Distance between the points (4, -2) and (7, -9) is sqrt(58) or approximately 7.62 units.

The distance between two points in a coordinate plane. The distance formula is based on the Pythagorean theorem and calculates the straight-line distance between two points.

The coordinates of the first point as (x1, y1) = (4, -2) and the coordinates of the second point as (x2, y2) = (7, -9).

The distance formula is given by:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values:

d = sqrt((7 - 4)^2 + (-9 - (-2))^2)

d = sqrt((3)^2 + (-7)^2)

d = sqrt(9 + 49)

d = sqrt(58)

Hence, the distance between the points (4, -2) and (7, -9) is sqrt(58) or approximately 7.62 units.

Based on the information given, the null hypothesis states that the newscast reaches 41% of the viewing audience, while the alternate hypothesis states that it does not reach 41% of the audience. So, the correct answer is d. Fail to reject the null hypothesis.

To determine the decision, we need to perform a hypothesis test using the given significance level α = 0.01. This significance level represents the maximum acceptable probability of making a Type I error, which is rejecting the null hypothesis when it is actually true.

In the survey of 100 viewers, 36% indicated that they watch the late evening news on the local CBS station. To test the hypothesis, we can use a one-sample proportion test. We compare this sample proportion to the claimed 41% to see if there is a significant difference.

Using a statistical calculator or software, we calculate the p-value associated with the observed sample proportion. If this p-value is less than α (0.01), we reject the null hypothesis. If the p-value is greater than or equal to α, we fail to reject the null hypothesis.

Based on the decision criteria, if the p-value is less than 0.01, we would reject the null hypothesis and conclude that the newscast does not reach 41% of the audience. However, if the p-value is greater than or equal to 0.01, we would fail to reject the null hypothesis. To summarize, the correct decision, given α = 0.01, would be d.

Answer:

no solution

Step-by-step explanation:

4x+3y = 6

8x + 6y = 5

Multiply the first equation by -2

-2(4x+3y) = 6*-2

-8x -6y = -12

Add this to the second equation

-8x-6y = -12

8x + 6y = 5

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

0x + 0y = -7

0 = -7

Since this is never true there is no solution

Answer:

X = 8/3, y= -14/9

Step-by-step explanation:

using elimination method:

subtract equation 1 from equation 2

8x-4x + 6y-3y = 5-6

4x+3y= -1

4x= -1-3y

divide both sides by 4

x = -1-3y÷4

substitute x = -1-3y/4 in equation 2

8(-1-3y)/4 +6y = 5

-8-24y/4+ 6y =5

-8-24y+6y/4 =5

-8-18y/4 = 5

Cross multy

-8-18y × 1 = 4×5

-8-18y = 20

collect like terms

-18y = 20+8

-18y = 28

divide both sides by-18

y = 28/-8

y = -14/9

put y = -14/9 in equation 1

4x+3(-14/9) = 6

4x-42/9 = 6

42/9 = 14/3

so, 4x=6+14/3

LCM =3

4x = 18+14/3

4x= 32/3

cross multiply

4x×3 = 32

12x = 32

divide both sides by 12

12x/12= 32/12

x = 8/3

so, x = 8/3, y = -14/9

check:

first equation:

4(8/3) + 3(-14/9)

32/3 - 14/3( 3 cancels 9 rem 3)

LCM= 3

32 - 14/3

Based on the net present value profile, Project H has a higher NPV than Project E.

To compare the net present value (NPV) of Project E and Project H, we need to calculate the present value of cash flows for each project and determine which one has a higher NPV. The cash flow patterns for the two projects are as follows:

Project E:

Initial investment: -$100,000

Cash flows for Year 1: $40,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $60,000

Project H:

Initial investment: -$120,000

Cash flows for Year 1: $60,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $40,000

To calculate the present value of cash flows, we need to discount them using an appropriate discount rate. The discount rate represents the required rate of return or the cost of capital for the company. Let's assume a discount rate of 10%.

Using the formula method, we can calculate the present value (PV) of each cash flow and sum them up to obtain the NPV for each project:

For Project E:

PV = $40,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $60,000/(1 + 0.10)^3

PV = $36,363.64 + $41,322.31 + $45,454.55

PV = $123,140.50

For Project H:

PV = $60,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $40,000/(1 + 0.10)^3

PV = $54,545.45 + $41,322.31 + $30,251.14

PV = $126,118.90

Using the financial calculator method, we can input the cash flows and the discount rate to calculate the NPV directly. By entering the cash flows for each project and the discount rate of 10%, we find that the NPV for Project E is approximately $123,140.50 and the NPV for Project H is approximately $126,118.90.

Answer:

321.50 dollars.

Step-by-step explanation:

Dena is buying wallpaper. It costs $8.79 per meter. She needs 120 feet. How much will the wallpaper cost? Round to the nearest half dollar.

This is a tricky math problem that requires some conversions and calculations. First, we need to convert feet to meters, because Dena lives in a country that uses the metric system. According to the search results   , one foot is equal to 0.3048 meters. So, 120 feet is equal to 120 x 0.3048 = 36.576 meters.

Next, we need to multiply the length of the wallpaper by the price per meter to get the total cost. The total cost is 36.576 x 8.79 = $321.38.

Finally, we need to round the total cost to the nearest half dollar. This means we need to look at the cents part of the cost and see if it is closer to 0, 50 or 100. In this case, 38 cents is closer to 50 than to 0 or 100, so we round up the cost to $321.50.

Therefore, Dena will have to pay $321.50 for the wallpaper. That's a lot of money for some paper that will probably peel off in a few years! Maybe she should consider painting her walls instead.

The formula for the probability of a geometric distribution is \(P(x) = (1 - p)^(x-1) * p\)

Given the probability of success (p) is 0.3, the probability of x being 4 would be:\(P(x) = (1 - 0.3)^(4-1) * 0.3\)

P(x) = 0.0729 or 7.29%

The geometric distribution is a probability distribution for the number of failures before the first success in a series of independent trials.

In this problem, the probability of success (p) is 0.3 and the probability of failure (1-p) is 0.7.

Therefore, the probability that x is 4 is given by the formula  \(P(x) = (1 - p)^(x-1) * p\)

The correct statement that compares cylinder A and cylinder B is B. The volume of cylinder B is 5 times the volume of cylinder A.

To compare the cylinders A and B, we need to consider their dimensions and properties.

Cylinder A:

Radius (r) = 6 cm

Height (h) = 10 cm

Cylinder B:

Radius (r) = 6 cm

Height (h) = 30 cm

To compare the two cylinders, we can focus on their volumes since the radius is the same for both. The formula for the volume of a cylinder is given by V = πr²h, where V represents volume, r represents radius, and h represents height.

For cylinder A:

Volume of cylinder A = π(6 cm)²(10 cm) = 360π cm³

For cylinder B:

Volume of cylinder B = π(6 cm)²(30 cm) = 1080π cm³

Comparing the volumes, we can conclude that the volume of cylinder B is greater than the volume of cylinder A.

Therefore, the correct statement that compares cylinder A and cylinder B is:

B. The volume of cylinder B is 5 times the volume of cylinder A.

Option A is incorrect since the height of cylinder B is not 5 times the height of cylinder A. Option C is also incorrect as the volume of cylinder B is not 3 times the volume of cylinder A. Option D is incorrect as the heights of cylinders A and B are different.
