Explanation:

1. Identify the different constellations of variables. Here there are three:

b
a
(none)

2. Combine coefficients of each of the different variable constellations:

(8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)

5.3b +7.8a +9.5

3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...

5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b

A parallelogram has an area of 28 square feet and a height of 4 feet. What is its base?

Leno4ka [110]

Answer:

Step-by-step explanation:

The area for a parallelogram is given by the following formula:

$A=bh$

Where b is the base and h is the height.

We already know the area is 28 and the height is 4. So, substitute:

$28=4b$

Divide both sides by 4:

$b=7$

So, the base length is 7.

Our answer is 7 :)

At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.

7. Order the numbers from greatest to<br> least.<br> (12.012 12.001 12.102 12.01

Arada [10]

Answer:

12.102, 12.012, 12.01, 12.001

Step-by-step explanation:

Since all of the numbers have the same numbers in the tens and ones places, the first place we need to compare is the tenths. The number with the greatest digit in the tenths place is 12.102, so it is first. The other numbers have a zero in the tenths place, so we move to the hundredths. 12.012 and 12.01 both have a one in the hundreds place, so we need to look at the thousandths. 12.012 is greater because it has a two in the thousandths place instead of a zero like 12.01, so it goes next, then 12.01, leaving 12.001 as the least.
