Avery uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She wants to buy 10 kg

Ksju [112]

Answer:

$d = m + 10\\d+m=150$

Step-by-step explanation:

If Avery wants the amount of dark chocolate (d) to be 10 kg higher than the amount of milk chocolate (m), then the following relationship must be true:

$d = m + 10$

If the total amount of chocolate must equal 150 kg, then:

$d+m=150$

The system of equations that represent this situation is:

$d = m + 10\\d+m=150$

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

Dahasolnce [82]

Answer: The parametric is being tested here is "p" (population proportion).

The hypothesis test is left-tailed.

Step-by-step explanation:

Given : The null and alternative hypotheses are

$H_0:\ p=0.2\\\\H_1:\ p$

The parametric is being tested here is "p", where p stands for population proportion.

Also, the type of test depends on the alternative hypotheses.

Since the alternative hypotheses is left-tailed, so the hypothesis test is left-tailed.

On the last day of school the fifth grade class has a picnic at the city park. Exactly 182 students and 274 adults are signed up

mamaluj [8]

Answer:

38 Tables

Step-by-step explanation:

First, we need to add the number of students with the number of adults to get the total number of people attending the picnic.

182 + 274 = 456

Next, we divide that number by how many people fit at each table to find how many tables we need.

456 people ÷ 12 people at each table = 38 tables.
