Answer:

The normal price of mixer is $150.

Step-by-step explanation:

Given that:

Normal prices are reduced by 15% in sale.

The normal price of mixer is reduced by $22.50

It means that it is the amount of discount.

Let,

x be the normal price of the mixer.

15% of x = 22.50

\(\frac{15}{100}x=22.50\\0.15x=22.50\)

Dividing both sides by 0.15

\(\frac{0.15x}{0.15}=\frac{22.50}{0.15}\\x=150\)

Hence,

The normal price of mixer is $150.

The normal price of the mixer is $150.

Given that,

Based on the above information, the calculation is as follows;

Let us assume the normal price be x

15%x = 22.50

0.15x = 22.50

x = $150

Answer:

625,000

Step-by-step explanation:

250,000 * 5/2 = 625,000

The commission that George will receive for the sale of a \(\$\)250,000, if he receives 2 1/2% of the selling price is $6,250.

"A commission is a piece of work that someone is asked to do and is paid for."

Sale is \(\$\)250,000

Converting 2 1/2% in improper fraction  is 5/2 %
So, commission will be \(\(2.5*250,000 /100\) = 625,000/100 = 6250

Hence, the commission that George will receive is $6,250.

(i) Exactly two of the events hold:

(a ∩ b) ∪ (a ∩ c) ∪ (b ∩ c)

(ii) At least one event holds:

a ∪ b ∪ c

The expression for "exactly two of the events hold" is found by considering all possible combinations of two events out of the three events (a, b, c) that can hold, while the other event does not hold. This is achieved by taking the union of the intersections of each combination of two events (a and b, a and c, or b and c) and the complement of the intersection of all three events.

The expression for "at least one event holds" is found by considering the union of all three events, which means that any of the events (a, b, c) can hold independently, or two or all three events can hold simultaneously. This is because the union of events represents the set of outcomes where at least one of the events holds.

The measure of angle W in the kite WXYZ is 115°

A kite is a quadrilateral with reflection symmetry across a diagonal. Because of this symmetry, a kite has two equal angles and two pairs of adjacent equal-length sides.

Given that, In kite WXYZ, m ∠ x = 90° and m ∠ z =40°.

Please refer to figure attached,

We know that, in a kite, it has two opposite and equal angles.

According to figure, here,

m ∠ W = m ∠ Y

Let m ∠ W = m ∠ Y = x

Also, the sum of interior angles of quadrilateral = 360°

Therefore,

x + x + 90° + 40° = 360°

2x = 360° - 130°

2x = 230°

x = 115°

Thus, m ∠ W = m ∠ Y = 115°  

Hence, the measure of angle W in the kite WXYZ is 115°

Step-by-step explanation:

As a result, there must be an x value such that the inequality is no longer true, and the parabola and the circle must intersect as a result.

The circle is centered at the origin on a coordinate grid, and the vertex of an upward-opening parabola is located at (0, 9). If the circle has a radius less than 9, the parabola and the circle must intersect.Let's suppose that the upward-opening parabola is y = ax² + 9. Since its vertex is (0, 9), this implies that a > 0, and therefore the parabola opens upwards. Since the circle is centered at the origin and has a radius less than 9, its equation is x² + y² < 81.We can substitute y with ax² + 9 in the inequality x² + y² < 81 and obtain:x² + (ax² + 9)² < 81This simplifies to:(a² + 1) x^4 + 18a² x² + 64 < 0Since the left-hand side of the inequality must be less than zero, it must be negative. Since x² is always non-negative, it follows that a² + 1 > 0. Thus, (a² + 1) x^4 + 18a² x² + 64 < 0 cannot be true for all x

Descriptive statistics summarizes or describes the characteristics of a data set. Descriptive statistics consists of two basic categories of measures: measures of central tendency and measures of variability (or spread). Measures of central tendency describe the center of a data set.

Answer:

99.48% probability that the sample mean would be greater than 64.8 kilograms.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean \(\mu\) and standard deviation(which is the square root of the variance) \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

\(\mu = 67, \sigma = \sqrt{121} = 11, n = 164, s = \frac{11}{\sqrt{164}} = 0.86\)

What is the probability that the sample mean would be greater than 64.8 kilograms?

This is 1 subtracted by the pvalue of Z when X = 64.8.

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{64.8 - 67}{0.86}\)

\(Z = -2.56\)

\(Z = -2.56\) has a pvalue of 0.0052

1 - 0.0052 = 0.9948

99.48% probability that the sample mean would be greater than 64.8 kilograms.

The number of square inches of cardboard that are needed to make one

We have,

The volume of the triangular prism.

= Area of the triangle x height

Now,

Height = 6 in

And,

To find the area of a triangle, we can use Heron's formula.

A = √(s(s-a)(s-b)(s-c))

where s is the semi-perimeter of the triangle, calculated as:

s = (a + b + c) / 2

In this case, the side lengths of the triangle are 3.2 in, 3.2 in, and 2 in.

Let's calculate the area using Heron's formula:

s = (3.2 + 3.2 + 2) / 2 = 4.2

A = √(4.2(4.2 - 3.2)(4.2 - 3.2)(4.2 - 2))

A = √(4.2 x 1 x 1 x 2.2)

A = √(9.24)

A ≈ 3.04 square inches

Now,

The volume of the triangular prism.

= Area of the triangle x height

= 3.04 x 6

= 18.24 in²

Now,

Answer:

B.the probability of buying bread and cheese is 0.12

Step-by-step explanation:

The probability of buying bread and cheese is 0.12.

The correct answer is option B.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

To determine if events A and B are independent,

We need to check if the occurrence of one event affects the probability of the other event.

If the events are independent, the probability of both events occurring can be calculated by multiplying the probabilities of each individual event.

Now,

Let A be the event that a shopper buys bread, and B be the event that a shopper buys cheese.

Then, we know that:

P(A) = 0.60 (the probability of buying bread)

P(B) = 0.20 (the probability of buying cheese)

If A and B are independent events, then the probability of both events occurring (i.e., the shopper buys both bread and cheese) is given by:

P(A and B) = P(A) x P(B)

Substituting the given values.

P(A and B)

= 0.60 x 0.20

= 0.12

This means that the probability of a shopper buying both bread and cheese is 0.12 if events A and B are independent.

Therefore,

The probability of buying bread and cheese is 0.12.

n = m + 5

The sum of the measures of the interior angles is

180(n - 2) for the n-sided polygon and

180(m  2) for the m-sided polygon.

"If the sum of interior angles of the regular
