Julia has 4 gallons 2 quarts of water.Ally needs the same amount of water but only has 12 quarts.How much more water does Ally n
ozzi
Ok so what do we know :
 
4 quarts = 1 gal
Julia has 4gal and 2 quarts or 18 quarts
ally has 12 quarts

so if julia has 18 quarts and ally has 12 that means that ally needs 6 more quarts (or 1gal 2 quarts) so that she and julia can have the same amount

Which two lines are parallel?<br> Which two lines are perpendicular?
lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = \frac{1}{2} x - 4 → with m = \frac{1}{2}

y = x + 1 → with m = 1

y = - \frac{1}{x} x - 3 → with m = - \frac{1}{2}

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - \frac{1}{2} x - 3 are Perpendicular since 2 × - \frac{1}{2} = - 1

How many women must be randomly selected to estimate the mean weight of women in one age group.we want 90% confidence that the s
mojhsa [17]
That is a very good question....

Look Grank

you know that:

confidence interval = mean +or- Margin of Error

and

Margin of Error = (z)*(standard deviation) / (sqrt of n)
where n is the number of sample records

So we need to calculate z-value firstly

It says: "<span>we want 90% confidence"

So that:
</span>
<span>confidence90% corresponds to z-value of 1.645

Plug that into our formula of </span><span>Margin of Error:

</span>Margin of Error = (1.645)*(22) / (sqrt of n)

"The sample mean is within 2.7 lb of the population mean" means that Margin of Error is 2.7

<span>Margin of Error:

</span>2.7 = (1.645)*(22) / (sqrt of n)

Now solve for n:

n=179.66~180

SO that 180<span> women must be randomly selected to estimate the mean weight of women in one age group.</span>

The diagram shows a square with side length 5cm.
arsen [322]

Answer:

5sqrt2

Step-by-step explanation:

Using the pythagorean theorem, we get 5^2+5^2=c^2. C is the diagonal here. 25+25=c^2, c^2=50. c=sqrt50. Simplifying it, we get the diagonal as 5sqrt2.
