Jermaine bought 9 large shirts for $12, and 12 small shirts for $8 for his 21 employees.

Let's represent the number of large shirts Jermaine bought as "L" and the number of small shirts as "S". We can set up a system of equations based on the information given:

L + S = 21 (equation 1, the total number of shirts is 21)

12L + 8S = 204 (equation 2, the total cost of the shirts is $204)

To solve for L, we need to eliminate S. We can do this by multiplying equation 1 by 8 and subtracting it from equation 2:

12L + 8S = 204

8L + 8S = 168 (multiply equation 1 by 8)

4L = 36

Dividing both sides by 4, we get:

L = 9

Therefore, Jermaine bought 9 large shirts for his 21 employees. We can find the number of small shirts by substituting L = 9 into equation 1:

L + S = 21

9 + S = 21

S = 12

So, by using linear equation system we find that Jermaine bought 9 large shirts and 12 small shirts for his 21 employees.

The probability that 11 or more of these consumers have called an 800 or 900 telephone number for information about some product is approximately 0.326.

The number of successes in a certain number of independent trials that all have the same probability of success are described by the discrete probability distribution known as the binomial probability distribution. The probability of success is constant during all trials, and it is used in statistics to describe situations where there are two alternative outcomes (success or failure).

The binomial probability distribution is given as:

P(X ≥ k) = 1 - P(X < k)

Here, p = 0.60, and the sample size is n = 20.

Thus,

P(X ≥ 11) = 1 - P(X < 11)

= 1 - ∑(20 choose x) (0.6)ˣ (0.4)⁽²⁰⁻ˣ⁾ for x from 0 to 10

P(X ≥ 11) = 0.326

In this case, it means that the company fails to identify components that absorb too much humidity, leading to a potential safety hazard for customers.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The consequence of a Type II error in this context is that the company believes the humidity absorbed is not more than 3%, when in fact it is more than 3%.

This means that the company will fail to detect components that absorb a dangerous level of humidity, and these components will be sold to customers, potentially causing a safety hazard. This is because the null hypothesis in this case is that the humidity level absorbed is 3%, and the alternative hypothesis is that it is more than 3%. A Type II error occurs when the null hypothesis is not rejected, even though it is false, and the alternative hypothesis is true.

Triangle JKL has a greater area than triangle XYZ, as it has an area of 98 square inches

To determine which triangle has the greater area, we need to use the formula for the area of a triangle, which is half the product of the base and height.

For triangle JKL, with a base of 14 inches and a height of 14 inches, we have:

Area = (14 x 14) / 2 = 98 square inches

For triangle XYZ, with a base of 20 inches and a height of 8 inches, we have:

Area = (20 x 8) / 2 = 80 square inches

Therefore, triangle JKL has a greater area than triangle XYZ, as it has an area of 98 square inches compared to 80 square inches for triangle XYZ. This is because the base and height of triangle JKL are both larger than those of triangle XYZ.

14.2665 feet above the ground

Step-by-step explanation:

We can use trigonometry to solve this problem. Let's call the height of the ladder on the wall "h". Then we have:

sin(72°) = h/15

Multiplying both sides by 15, we get:

h = 15 sin(72°)

Using a calculator, we find that sin(72°) is approximately 0.9511. So:

h ≈ 15 × 0.9511

h ≈ 14.2665

Therefore, the top of the ladder is approximately 14.2665 feet above the ground.

If Sam purchases a new car for $29,500 and the car depreciates at a rate of 13. 25% per year, then the value of the car after 7 years is $11652.50

We can use the formula for exponential decay to find the value of the car after 7 years:

V = P × e^(-rt)

where:

V = value of the car after 7 years

P = initial price of the car

r = annual depreciation rate (as a decimal)

t = time in years

Plugging in the values we get:

V = 29500 × e^(-0.1325 × 7)

V = 29500 × e^(-0.9275)

Answer:

From the problem, we know that:

s + h = 137 (the total number of sodas and hot dogs sold is 137)

s = h + 49 (the number of sodas sold is 49 more than the number of hot dogs sold)

Now we can substitute the second equation into the first equation:

(h + 49) + h = 137

Simplifying this equation:

2h + 49 = 137

Subtracting 49 from both sides:

2h = 88

Dividing both sides by 2:

h = 44

Now we know that 44 hot dogs were sold. We can use the second equation to find the number of sodas sold:

s = h + 49

s = 44 + 49

s = 93

Therefore, 93 sodas were sold.

Number of sodas sold: 93

Number of hot dogs sold: 44

Step-by-step explanation:

Answer: Let's use variables to represent the number of sodas and hot dogs sold.

Let x be the number of hot dogs sold.

According to the problem, the number of sodas sold was 49 more than the number of hot dogs sold, so the number of sodas sold is x + 49.

The problem also tells us that the combined total of sodas and hot dogs sold was 137. So we can set up an equation:

x + (x + 49) = 137

Simplifying the left side:

2x + 49 = 137

Subtracting 49 from both sides:

2x = 88

Dividing both sides by 2:

x = 44

So the number of hot dogs sold was 44.

To find the number of sodas sold, we can use the expression we set up earlier:

x + 49

Substituting in our value for x:

44 + 49 = 93

So the number of sodas sold was 93.

Answer: Number of sodas sold: 93, Number of hot dogs sold: 44.

z = (x - μ) / σ,
where x is the data point, μ is the mean, and σ is the standard deviation.

a. The z-score for a backyard structure costing $2300 can be calculated as follows:

z = (2300 - 3100) / 1200 = -800 / 1200 = -0.67

b. The z-score for a backyard structure costing $4900 can be calculated as follows:

z = (4900 - 3100) / 1200 = 1800 / 1200 = 1.

c. The z-score in part (a) is -0.67, which means that the backyard structure costing $2300 is 0.67 standard deviations below the mean. The z-score in part (b) is 1.5, which means that the backyard structure costing $4900 is 1.5 standard deviations above the mean. Neither of these z-scores are extreme enough to be considered outliers, as they are both within 2 standard deviations of the mean.

d. The z-score for the backyard shed-office combination costing $13,000 can be calculated as follows:

z = (13000 - 3100) / 1200 = 9900 / 1200 = 8.25

Expression B has the least value if  g and h are whole numbers, and

g < h.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Given that,

g < h

To determine which expression has the least value, we need to simplify each expression as much as possible and compare the results.

First, let's simplify expression A:

A = (h + g) * (h - g)

 = h*h - g*g

Next, let's simplify expression B:

B = h*h- 2hg + g*g

Finally, let's simplify expression C:

C = h*h + 2hg + g*g

Now we can compare the expressions. We know that g < h, so g*g < h*h. Therefore, the smallest value will be produced by the expression with the smallest coefficient for the h*h term.

A has a coefficient of 1 for the h*h term, while B and C have coefficients of -2h and 2h, respectively. Since h is positive, -2h is the smallest coefficient, so expression B has the smallest value.

Therefore, expression B has the least value.

What is Probability?

Probability is a branch of mathematics concerned with measuring the likelihood of events. It involves studying random phenomena, such as coin tosses, rolling dice, or weather patterns, and assigning numerical values to the likelihood of different outcomes .The formal definition of probability is based on the concept of equally likely outcomes, where the probability of an event is the ratio of the number of favorable outcomes to the total number of outcomes

If P(X) = 0.66, then the probability of not X occurring (i.e., X complement or X bar) is:

P(X bar) = 1 - P(X)

P(X bar) = 1 - 0.66
