Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Thus the equation is y = (1)x + (-4), or y = x - 4.

Kamrynn is looking at her five quiz scores of 96 90 94 93 and 90. Determine the mean rounded to the nearest tenth median mode an

Romashka [77]

Answer:

Mean = 90, Median = 93, Mode = 90, Range = 6

Step-by-step explanation:

Mean:

96 + 90 + 94 + 93 + 90 = 463

463 ÷ 5 = 92.5

92.5 to nearest tenth = 90

Mean = 90

Median:

90, 90, 93, 94 ,96

Median = 93

Mode

96, 90, 94, 93, 90

Mode = 90

Range:

96 - 90 = 6

Range = 6

It takes 212121 minutes for 555 people to paint 777 walls. How many minutes does it take 333 people to paint 555 walls?

Papessa [141]

Solution: We are given that:

5 people can paint 7 walls in 21 minutes

Therefore, 1 person can paint 7 walls in $21 \times 5=105$ minutes

Which means 1 person can paint 1 wall in $\frac{105}{7} =15$ minutes

Now, 3 people can paint 1 wall in $\frac{15}{3} =5$ minutes

Therefore, 3 people can paint 5 walls in $5 \times 5=25$ minutes

Simplify 425xy⁴/25xy²

beks73 [17]

We have the expression

$\frac{425xy^4}{25xy^2}$

We can already simplify x because it's both on the numerator and denominator

$\frac{425y^4}{25y^2}$

Now we can simplify 425/25 = 17

$\frac{17y^4}{y^2}$

Remember that

$\frac{a^n}{a^m}=a^{n-m}$

Then

$17y^{4-2}=17y^2$

The final result is

$17y^2$
