In a clothing store, 65% of the customers buy a shirt, 30% of the customers

Mathematics
1 answer:
diamong [38]3 years ago
4 0

Answer:

75%

Step-by-step explanation:

List out known probabilities

\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}

recall equation

\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)

Plug in values

\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%

  1. To divide the triangles into these regions, you should construct the <u>perpendicular bisector</u> of each segment.
  2. These perpendicular bisectors intersect and divide each triangle into three regions.
  3. The points in each region are those closest to the vertex in that <u>region</u>.

<h3>What is a triangle?</h3>

A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<h3>What is a perpendicular bisector?</h3>

A perpendicular bisector can be defined as a type of line that bisects (divides) a line segment exactly into two (2) halves and forms an angle of 90 degrees at the point of intersection.

In this scenario, we can reasonably infer that to divide the triangles into these regions, you should construct the <u>perpendicular bisector</u> of each segment. These perpendicular bisectors intersect and divide each triangle into three regions. The points in each region are those closest to the vertex in that <u>region</u>.

A production line operation is designed to fill cartons with laundry detergent to a mean weight of 32 ounces. A sample of carton
IgorLugansk [536]

Answer:

Step-by-step explanation:

a) The null hypothesis states that

The production line operation fills cartons with laundry detergent to a mean weight of 32 ounces.

H0 : µ = 32

The alternative hypothesis states that

The production line operation overfills or under fills cartons with the laundry detergent to a mean weight of above or below 32 ounces.

Ha : µ ≠ 32

b) when the calculations are done and the p value is determined, then it would be compared with the level of significance

When the significance level is lesser than the p value, we do not reject H0 because there is no sufficient evidence to conclude that the production line operation overfills or under fills cartons.

c) When the significance level is greater than the p value, we would reject H0 because there is sufficient evidence to conclude that the production line operation overfills or under fills cartons.
