Step-by-step explanation:

In two hours, the amount will be; 1.5 × 2

= 3cm

in the three hours, the amount will be 1.5×3

=4.5cm

in four hours, the amount will be; 1.5×4

=6cm

in five hours, the amount will be; 1.5×5

=7.5cm

The question asks you to find the total amount of rain after each hour, and has given you the ratio of 1.5 cm of rain in an hour. Therefore to find the rest, you’ll need to multiply the number of hours by the amount of rain in an hour:
2hrs - 3 cm
3hrs - 4.5 cm
4hrs - 6 cm
5hrs - 7.5 cm

I hope this helps and that I’m right! Good luck!! :)

If we think about a normal curve / bell curve and the 68-95-99.7 rule, we know that the majority of data will lie within 1, 2, or 3 standard deviations from the mean. The mean is in the center of the curve, and to each side of the mean, 34% of the data lies 1 standard deviation on either side of the mean. Therefore, we need to add and subtract one standard deviation from the mean.

85 + 12 = 97

85 - 12 = 73

Correct Answer: B. 73 - 97

Hope this helps!! :)

What is the base if the height is 6ft and the area is 14 ft on a triangle ​
insens350 [35]

Answer:

b = 4.66666667

Step-by-step explanation:

The equation for finding the area of a triangle is

0.5b x h = a

b = base

h = height

a = area

So I calculated 14 divided by 6

And got 2.3333333

And since that number is half of the base, I multiplied it by 2

2.333 x 2 ≈ 4.66666667

Here is the histogram of a data distribution. All class widths are 1.
vaieri [72.5K]
The answer is 7 because the mean is an average. So if you add up all the numbers and then divide that number by the amount of numbers listed then that will get you your answer which is 7

4+5+6+7+8+9+10=49
49/7=7
