Definition of additional: MORE, more, <em>and</em> more.
<em>Not </em>a definition of additional: SAME, same, and same.

We are given that EF is parallel to GH.
Remember, the definition of additional.

We wouldn't want the same piece of information, would we?

That's why we want a new piece of information:
Answer Choice B; FG parallel to EH.

Find the mid point of PQ if P (0,0) and Q (5, 12)

Simora [160]

Using the midpoint formula we get:

(x,y)=(0+5/2, 0+12/2) or (5/2, 6) as the midpoint.

Huxian's father gives her $120 as her monthly allowance. a) If she spends an average of 5 dollars a day, find the amount on mone

abruzzese [7]

Answer:

3 days= $105, 6 days= $90, 10 days= $70

Step-by-step explanation:

You can rewrite this equation as y=120-5x

x is the amount of days passed

plug in 3 for x and you get 15. 120-15=105

plug in 6 for x and you get 30. 120-30=90

plug in 10 for x you get 50. 120-50=70

Hope this helps!

A flashlight battery manufacturer makes a model of battery whose mean shelf life is three years and four months, with a standard

Vladimir [108]

Answer:

17,065 of those batteries can be expected to last between three years and one month and three years and seven months

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem:

I will calculate the time in months. Each year has twelve months.

Mean shelf life is three years and four months, with a standard deviation of three months. So

$\mu = 3*12 + 4 = 40$

$\sigma = 3$

Proportion lasting between three years and one month and three years and seven months:

This is the pvalue of Z when X = 3*12 + 7 = 43 subtracted by the pvalue of Z when X = 3*12 + 1 = 37

X = 43

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{43 - 40}{3}$

$Z = 1$

$Z = 1$ has a pvalue of 0.8413.

X = 37

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{37 - 40}{3}$

$Z = -1$

$Z = -1$ has a pvalue of 0.1587.

0.8413 - 0.1587 = 0.6826

Out of 25,000 batteries:

68.26% of the batteries are expected to last between three years and one month and three years and seven months.

0.6826*25000 = 17,065

17,065 of those batteries can be expected to last between three years and one month and three years and seven months

a local hamburger shop sold a combined total of 456 hamburgers and cheeseburgers. The number of cheeseburgers sold was three tim

Ganezh [65]

H + c = 456
c = 3h

h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold

c = 3h
c = 3(114)
c = 342......cheeseburgers sold

18 times the quantity g plus 5

soldi70 [24.7K]

Answer:

Step-by-step explanation:

Comment

The first thing you should notice once you have read it, is there is a plus sign required. That means you are likely to get a binomial (two different things that won't reduce or combined).

So what you get is

18*g + 5

Notice where the place sign is. It is between 18g and 5. The result cannot be simplified any further.

Answer

18g + 5
