Answer:

1.50

Step-by-step explanation:

You want to find how much more per hour Liz earned at the beach.

First, find the unit rate for each lifeguarding job.

At the pool, Liz earned $46.50 for 6 hours of lifeguarding.

$46.50÷6

6hours÷6

=

$7.75

1hour

At the beach, Liz earned $46.25 for 5 hours of lifeguarding.

$46.25÷5

5hours÷5

=

$9.25

1hour

Then, subtract the unit rates.

$9.25–$7.75=$1.50

Liz made $1.50 more per hour at the beach than she did at the pool.

A shelf is built on a wall, as shown below. What is the value of x?
sp2606 [1]

Answer:

Step-by-step explanation:

Given:

A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°

We need to determine the value of x.

Value of x:

By triangle sum property, the angles in a triangle always add up to 180°

Thus, we have;

Simplifying, we get;

Subtracting both sides by 75, we get;

Dividing both sides of the equation by 3, we get;

Thus, the value of x is 35.

What are the first four terms in the multiplication, or geometric, pattern in which the first term is 7 and then each term is mu
alexgriva [62]
They tell you that the first term is 7 so that cancels out the last answer choice immediately. Then they tell you that each term is multiplied by 4 so when you multiply 7x4 you get 28. This cancels out the second to last answer. Then keep multiplying by 4. 28x4 is 112. 112x4 is 448.
Therefore, the obvious answer is the first choice!

In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five tre
yawa3891 [41]

Answer:

MSE = 10

Step-by-step explanation:

Given

SSTR = 200

SST = 800

Required

Determine MSE

This is calculated as:

MSE = \frac{1}{ddf} * SSE

Where:

SSE = SST - SSTR

ddf \to denominator df

So, we have:

SSE = 800 - 200

SSE = 600

To calculate the df, we have:

r = 13 --- observations

n = 5 treatments

So:

ddf = Total\ df - Numerator\ df

Total = n*r-1 = 5*13 -1 = 64

Numerator =n - 1 = 5 - 1 =4

ddf =64-4=60

So, we have:

MSE = \frac{1}{ddf} * SSE

MSE = \frac{1}{60} * 600

MSE = 10
