Answer:

-5/2

to find slope you have to do y2-y1 over x2-x1 so it would be

16-6/15-19 ect.

How to find the missing lengths of a partelogram
Levart [38]

Answer:

Below.

Step-by-step explanation:

The area = the height (h) times the base.

So Q2:

21 = h * 7

h = 21/7 = 3

55 = b * 5

b = 11.

18.75 = h * 7.5

h = 18.75 / 7.5

= 2.5.

in one day Annie traveled 5 times the sum of the number of hours Brian traveled and two together they travel 20 hours find this
Stels [109]

Use the distributive property:

5*b+5*2+b=20

5b+10+b=20.

Combine like terms:

6b+10=20.

Subtract 10 from both sides:

6b+10-10=20-10

6b=10.

Divide both sides by 6:

6b/6=10/6

b=5/3=1 2/3.

Brian travels 1 2/3 hours. This means Annie travels

5(1 2/3+2)=5(3 2/3)=5(11/3)=55/3=18 1/3 hours.

Hope this helps!

A study on students drinking habits asks a random sample of 60 male UF students how many alcoholic beverages they have consumed
Alex17521 [72]

Answer:

A. (4.78, 6.90)

Step-by-step explanation:

Using the following formulas the lower and upper limits of the Interval are calculated

Lower limit = mean - (standard deviation /√sample size)* Zr

Upper limit = mean + (standard deviation /√sample size)* Zr

Zr depends on confidence interval  and can be found in a z table

Zr for 90% = 1.645

then

Lower limit = 5.84 - (4.98 /√60)* 1.645 = 4.78

Upper limit = 5.84 + (4.98 /√60)* 1.645 = 6.90

How to create an equation with infinitely many solutions.
AlekseyPX

Answer:

4 x + 5 = 2 x + 2 x + 5

Step-by-step explanation:

If we simplify the following equation it will be 4 x + 5 = 4 x + 5. This equation has infinitely many solutions because every value for x we substitute in, it will be the same on both sides, for example

Substitute x = 7 into 4 x + 5 = 4 x + 5

4 × ( 7 ) + 5 = 4 × ( 7 ) + 5

28 + 5 = 28 + 5

33 = 33

Every x value that we substitute in will result in the equation having the same result on both sides
