Answer:

f(x) = 3x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m = $\frac{3-0}{1-0}$ = 3 , then

y = 3x ← is the equation of the graphed line

Together, teammates Pedro and Ricky got 2688 base hits last season. Pedro had 284 more hits than Ricky.

Yakvenalex [24]

Answer:

Pedro got 1486 and Ricky got 1202 hits

Step-by-step explanation:

We have that, teammates Pedro and Ricky together got 2688 base hits last season.

This means $p+r=2688$ , where p is the number of hits Pedro got and r number of hits Ricky got.

Also Pedro had 284 more hits than Ricky.

This gives us:

$p=r+284$

We substitute this last equation into the first one to get:

$r+284+r=2688$

2r=2404

Divide by 2 to get:

r=1202

Therefore p=1202+284=1486

Suppose y varies directly with x. If y = 12 when x = 4, find x when y = 24.

mash [69]

Answer:

x would equal 8.

Step-by-step explanation:

Since when y = 12, x = 8, when y is 24, it is multiplied by 2. Multiple the x by 2 and it would be 8.

C. Stratified Sampling

Step-by-step explanation:

Stratified sampling is a sampling method in which the overall population is divided into a number of smaller sub groups.

These smaller sub-groups are called as strata.

These sub-groups are formed on the basis of similar characteristics and attributes shared by the population.

It is also known as proportional random sampling.

A pack of 6 batteries of the same type cost ?2.79 . By calculating the price per battery,determine if this is better value.You m

MissTica

Answer:

The full question is attached in the picture below.

The better price for the battery is given with the 6 pack.

(£ 0.47 per battery)

Step-by-step explanation:

If 8 batteries cost £ 3.99

This means that one battery is equal to

£3.99/8 = £ 0.49875 ≈ £ 0.50 per battery

The pack of 6 batteries costs £ 2.79

This means that one battery is equal to

£2.79/6 = £ 0.465 ≈ £ 0.47 per battery

Then, we can conclude than the 6 pack gives us a better price per battery
