Answer:

x is y less than z

Step-by-step explanation:

The given equation is x + y = z

This equation relates the whole numbers x, y, and z.

This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.

Making y the subject of the formula, it becomes

y = z-x (this shows that z is greater than y by x)

Making x the subject of the formula, it becomes

x = z-y (this shows that z is greater than x by y)

Looking at the options given, the correct comparisons between z and x is

x is y less than z

mezya [45]

Answer:

Eric can either charge $10 or $40 in order to break even.

Step-by-step explanation:

Eric has a summer lawn mowing business and the equation:

p=-3x^2+150x-1200

Models his total profit <em>p</em> by charging <em>x</em> dollars per lawn.

We want to determine what price Eric needs to charge in order to break even.

The price Eric charges to break even means that his total profit will be zero. Hence, we can let <em>p</em> = 0 and solve for <em>x</em>. Thu:

0=-3x^2+150x-1200

We can divide both sides by -3:

0=x^2-50x+400

Factor:

0=(x-10)(x-40)

Zero Product Property:

x-10=0\text{ or } x-40=0

Solve for each case. Hence:

x=10\text{ or } x=40

Therefore, Eric can either charge $10 or $40 in order to break even.

Answer:

a. 5.26

Step-by-step explanation:

As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.

t score=Xbar A- Xbar B/Sd of difference of means

t score=55-51/0.76

t score=4/0.76=5.26
