arlik [135]

-3(4-2y)=24

Apply distributive property

-12+6y=24

Add 12 to both sides

6y=36

Divide both sides by 6

y=6

Write the converse of this statement.if two angles are both obtuse, the two angles are equal.

Aliun [14]

To form the converse of the conditional statement, interchange the hypothesis and the conclusion.

Given conditional statement: "if two angles are both obtuse, the two angles are equal".

Here,

hypotesis is: two angles are both obtuse,
conclusion is: two angles are equal.

Then the converse statement will be: "If two angles are equal, then two angles are both obtuse".

A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 5 trays and

Alexeev081 [22]

Answer:

4 trays should he prepared, if the owner wants a service level of at least 95%.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 5

Standard Deviation, σ = 1

We are given that the distribution of demand score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X > x) = 0.95

We have to find the value of x such that the probability is 0.95

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 5}{1})=0.95$

$= 1 -P( z \leq \displaystyle\frac{x - 5}{1})=0.95$

$=P( z \leq \displaystyle\frac{x - 5}{1})=0.05$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 5}{1} = -1.645\\x = 3.355 \approx 4$

Hence, 4 trays should he prepared, if the owner wants a service level of at least 95%.
