Answer:

yes

Step-by-step explanation:

A rational number can be expressed in the form

$\frac{a}{b}$ ← where a and b are integers

The 5 in .65 is in the hundredths position , thus

5.65 = 5 $\frac{65}{100}$ = $\frac{5(100)+65)}{100}$ = $\frac{500+65}{100}$ = $\frac{565}{100}$ ← a rational number

krek1111 [17]

Answer:

34%

Step-by-step explanation:

According to the empirical rule, 68% of all of the data in a normal distribution falls within one standard deviation of the mean.

Applying to this particular case, 68% of the requests fall within (50 - 7) and (50+ 7). The percentage of requests from 43 to 50 is equal to the percentage of requests from 50 to 57.

Therefore, the percentage of light bulb replacement requests numbering between 50 and 57 is 68/2 = 34%.

What is the equation of the line, in point slope form, that passes through the points (4,8) and (2,-2)

Solnce55 [7]

Answer:

Step-by-step explanation:

1) point slope form is:

y-y1=m(x-x1)

y1=8

x1=4

m=(slope)

to find m: y2-y1/x2-x1

hence

-2-8/2-4=-10/-2=5

m=5:

y-8=5(x+4)

Kyla can plant 300 trees in 1 hour

attashe74 [19]

We have to find out the number of trees planted per unit rate of time.

Kyla can plant 300 trees in 1 hour, so she can plant 300 trees in 3600 seconds. This implies that she can plant

$\dfrac{300}{3600}=\dfrac{1}{12}$

trees per second.

On the other hand, Mia can plant 1 tree in 13 seconds, so she can plant

$\dfrac{1}{13}$

trees per second.

Working together they can plant

$\dfrac{1}{12}+\dfrac{1}{13}=\dfrac{25}{156}$

trees per second, i.e. it takes them 156/25 seconds to plant a tree.

We conclude that they plany 100 trees in

$\dfrac{156}{25}\cdot 100=156\cdot 4=624$

seconds
