The area of a triangle is 115 in2. If the height of the triangle is 7.5 inches, what is the length of its base? Round to the nearest hundredth, if necessary.

Answers

Answer 1

Answer:

30.67 inches

Step-by-step explanation:

Area of a triangle: 1/2 x b x h

115 = 1/2 x b x 7.5

115 = 3.75b

115/3.75 = b

30.66666 = b

30.67 = b

what is the mean age of the 8 golfers

Answers

Answer:

27.25 Years Old

Step-by-step explanation:

Find the total age of the 17 golfers.

52(17) = 884

Find total age of the 9 golfers.

9(74) = 666

Subtract.

884 - 666 = 218

Divide by the 8 golfers.

218/8 = 27.25

The median rainfall during a spring storm in the lowlands is about 4 mm less than a spring storm in the highlands. The mean rainfall for the lowlands is about 3 mm less than for the highlands. Why is there a difference in the central measures for each data set?

Answers

Answer:

There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.

Step-by-step explanation:

Answer:

There is a difference since there could be more rainy days in the spring than on other days. As a result, the mean for the spring would be higher than on other days.

Answers

Answer:

Step-by-step explanation:

When we add the area of semicircle I and III  of same radius, we get a cirlce.

diameter = 48 cm

r = 48/2 = 24 cm

Area of I and III = area of circle

                         = πr²

                         = 3.14 * 24 *24

                         = 1808.6 cm²

Figure II:

length =  diameter of the bigger semicircle = 48 cm

width = diameter of the smaller circle = 14 cm

Area of rectangle (figure II) = length *width

                                            = 48 * 14

                                            = 672 cm²

Smaller semicircle A & B

diameter = 14 cm

r = 14/2 = 7 cm

Area of Semicircle A & B = Area of a circle

                                         [tex]\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}[/tex]

Area of shaded region =  area of rectangle II + area of figure I & III - area of A &B

            = 672 + 1808.6   - 154

           =  2326.6cm²

Answers

Answer:

12

Step-by-step explanation:

Differentiate the equation. It will give you -1/6x + 2 = dy/dx.

Let dy/dx = 0 (you do this because the highest point is usually the turning point. The gradient is zero at the turning point, meaning that you'd have to set dy/dx to be zero to figure out the highest point).

Then rearrage for x

-1/6x+2=0

1/6x = 2

x = 12

Answer:

Option A for part (a) and Option B for part (b)

Step-by-step explanation:

Step 1:  Determine the ratios in part a

First Batch --> 8 minutes / 2 customers = 4 minutes per customer

Second Batch --> 18 minutes / 6 customers = 3 minutes per customer

Third Batch --> 21 minutes / 7 customers = 3 minutes per customer

In part (a) we would choose option a which is that it does not always take the same amount of time to serve each customer.

Step 2:  Determine the ratios in part b

First Batch --> 27 points / 3 dollars = 9 points per dollar

Second Batch --> 45 points / 5 dollars = 9 points per dollar

Third Batch --> 63 points / 7 dollars = 9 points per dollar

In part(b) would choose option b which is that each dollar spent appears to earn the same number of points which would give us 8 dollars for 72 points.

Answer: Option A for part (a) and Option B for part (b)

A bicycle manufacturer is studying the reliability of one of its models. the study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent. if the probability of a defect with the brakes or the chain is 6 percent, what is the probability of a chain defect? 1.5 percent 2 percent 2.5 percent 3 percent

Answers

Using Venn probabilities, it is found that there is a 0.03 = 3% probability of a chain defect.

What is a Venn probability?

In a Venn probability, two non-independent events are related to each other, as are their probabilities.

The "or probability" is given by:

[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)[/tex]

In this problem, the events are:

Event A: Brake defect.

Event B: Chain defect.

For the probabilities, we have that:

The study finds that the probability of a brake defect is 4 percent, P(A) = 0.04.

The probability of both a brake defect and a chain defect is 1 percent, P(A∩B) = 0.01.

The probability of a defect with the brakes or the chain is 6 percent, P(A∪B) = 0.06.

Substitute all the values in the formula

[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)\\\\0.06=0.04+P(B)-0.01\\\\P(B)=0.06-0.04+0.01\\\\ P(B)=0.03[/tex]

0.03 = 3% probability of a chain defect.

Hence, there is a 0.03 = 3% probability of a chain defect.

For which value of m does the graph of y = 18x2 + mx + 2 have exactly one x-intercept?

Answers

Answer:

The graph y = 18x2 + mx + 2= 12

So the answer is 12

The value of m does the graph of y = 18 x² + m x + 2 have exactly one x-intercept is 12.

What is Intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

We have Equation.

y = 18 x² + m x + 2

Now, to find exactly one intercept we will use Discriminant Method as

D = m² - 4 x 18 x 2 = 0

m² - 144 = 0

m² = 144

m = -12 or m = 12

Thus, the required value of m is 12.
