The ration is 12 muffins to every 21 donuts

Muffins/Donuts = (substitute the values) 24/42, and then simplify the fraction. So the ration is 4/7 or 4:7.

A hypothesis test was used to see if less than 5% of all Americans would still drive to work if gas prices went above $10.00 a g

Kruka [31]

Answer:

The correct option is;

False

Step-by-step explanation:

Here, we note that the proportion of the test statistic which is used in the test is 5% and the P-value for the test is 0.03

The hypothesis test is meant to check if people will still drive to work when the gas prices are above $10.00 and the suggestion was that we can conclude that when the fuel price is above $5.00 everyone would still drive to work without a P-value for the test, hence we can not come to the stated conclusion.

5 1/2 + 3 4/5 + 1 1/4 =

ratelena [41]

Answer:

$10\frac{11}{20}$

Step-by-step explanation:

$5\frac{1}{2} + 3\frac{4}{5} + 1\frac{1}{4}$

1.Find the LCM(Least Common Multiple).

That would be 20.

2.Multiply so all denominators are equal.

$5\frac{10}{20} + 3\frac{16}{20} + 1\frac{5}{20}$

3. Add

$9\frac{31}{20}$

4. Simplify

$10\frac{11}{20}$

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=4 and BC=3, Find AH, CH and BH.

IRISSAK [1]

Answer:

AH = 3.2
CH = 1.8
BH = 2.4

Step-by-step explanation:

It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...

AC^2 = AB^2 + CB^2

AC^2 = 4^2 + 3^2 = 16 + 9 = 25

AC = √25 = 5

The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...

scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8

And the scale factor to ∆BHC is ...

scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6

Then the side AH is 0.8·AB = 0.8·4 = 3.2

And the side CH is 0.6·BC = 0.6·3 = 1.8

These two side lengths should add to the length AC = 5, and they do.

The remaining side BH can be found from either scale factor:

BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4

_____

The sides of interest are ...

AH = 3.2

CH = 1.8

BH = 2.4
