Amanda earned a score of 940 on a national achievement test that was normally distributed. The mean test score was 850 with a st

snow_lady [41]

In math notation, we've done this: z = (X - μ) / σ = (940 - 850) / 100 = 0.90 where z is the z-score X is Vivian's score (940) µ is the mean (850) σ is the standard deviation (100) As you may know, in a normal distribution it's expected that about 68% of all observations will fall within 1 standard deviation of the mean, 95% will fall within 2 standard deviations, and 99% will fall within 3 standard deviations.
940 lie before the first standard deviation, in which 16.5% is above it
since 940 is 0.9 from the mean and 0.1 from the first standard deviation
so above it is 17.5 % = 0.175 or about 0.18

What is the converse of the statement? "If x - 2 = 5, then x = 7"

dlinn [17]

ANSWER

"If x=7, then x - 2 = 5"

EXPLANATION

Let

$p \to \: q$

be a propositional statement.

The converse of this statement is

$q \to \: p$

In other words, the converse of the statement,

"If p then q" is "If q, then p"

The given given conditional statement is

"If x - 2 = 5, then x = 7"

Therefore the converse is

"If x=7, then x - 2 = 5"

F. Please answer this as soon as possible.

Liono4ka [1.6K]

Answer:

-12

Step-by-step explanation:

Convert the mixed number to an improper fraction.

-2 $\frac{2}{3}$ = $-\frac{8}{3}$

To divide, just multiply by the reciprocal.

So -2 $\frac{2}{3}$ ÷ $\frac{2}{9}$ becomes $-\frac{8}{3}$ ÷

Now you can multiply straight across.

$-\frac{8}{3}$ × $\frac{9}{2}$ = $-\frac{72}{6}$

And simplify.

$-\frac{72}{6}$ = -12

rewona [7]

Answer:

I will make $ 13.20 per hour

Step-by-step explanation:

Given:

Employee gets money for Working from 2.00 PM to 6.00 PM = $\$ 12$ per hour

Employee gets money for working from 6.00 PM to 12.00 AM will get additional 10 $\%$ = $\frac{10}{100}\times12= \$ 1.2$ per hour

Employee gets money for working from 12.00 AM to 01.00 AM will get additional 15 $\%$ = $\frac{15}{100}\times12= \$ 1.8$ per hour

Solution:

Employee works from 2.00 PM to 12.00 AM= Employee gets money for Working from 2.00 PM to 6.00 PM + 10 $\%$ extra wage = $\$ 12 + \$ 1.2 = \$ 13.2$
