Answer:

Step-by-step explanation:

Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.

Let x represents the amount of good quality forever paint sold.

Total amount of paint $=48+45+35+39+33+x=200+x$ ...(i)

Experimental probability of paint sold will be better quality durable paint is

$P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}$

$P=\dfrac{45}{\text{Amount of total paint}}$

It is given that experimental probability of paint sold will be better quality durable paint is $\frac{9}{50}.$

$\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}$

$\text{Amount of total paint}=\dfrac{45\times 50}{9}$

$\text{Amount of total paint}=250$ ...(ii)

From (i) and (ii), we get

$200+x=250$

$x=250-200$

$x=50$

Therefore, 50 gallons good quality forever paint is sold.

Find the slope of the line that passes through the points (2, 4) and (6, 12)

Aleks [24]

The answer is 2.

The formula for slop is y2-y1/x2-x1
Using this formula we get 12-4/6-2 or 8/4 which simplifies to 2.

Hope this helps!

7. for normal situations, the minimum speed limit throughout the u.s. interstate highway system is 72 km/hr which is 45 miles pe

gladu [14]

Answer:

Question 7: Distance = 237.6 km

Question 8: Distance = 399.3 km

Step-by-step explanation:

Question 7:

Given:

Minimum speed (s) = 72 km/hr

Time taken (t) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Minimum speed × Time

Distance = $s\times t$

Distance = $72\times 3.3 = 237.6\ km$

Therefore, distance traveled at this speed is 237.6 km.

Question 8:

Maximum speed (S) = 121 km/hr

Time taken (T) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Maximum speed × Time

Distance = $S\times T$

Distance = $121\times 3.3 = 399.3\ km$

Therefore, distance traveled at this speed is 399.3 km.
