Dennis_Churaev [7]

Answer: Felipe made 24 sand art bottles.

Step-by-step explanation:

Given: Total different colors of sand = 9

Weight of each color sand = 1 pound

Then, the weight of all 9 colors would be 9 × 1 = 9 pounds

Since 1 pound = 16 ounces

Then, 9 pounds = 9 × 16 = 144 ounces

capacity of each bottle = 6 ounce

Then, the number of bottles required = ( 144 ounces) ÷ 6

= 24

Hence, Felipe made 24 sand art bottles.

The cost of using 19 HCF of water is $32.49

Given in the question:

The monthly cost (in dollars) of the water use (in dollars) is a linear function of the amount of water used (in hundreds of cubic feet, HCF)

The cost for using 17 HCF of water is using $32.13

and, the cost of using 35 HCF is $61.83.

To find the cost of using 19 HCF of water.

Now, According to the question:

The cost for using 17 HCF of water is $32.13

and, the cost of using 35 HCF is $61.83.

To find the slope:

(17, 32.13) and (35, 61.83)

Slope = (61.83 - 32.13)/ (35 - 17) = 1.65

We know that:

Formula of slope :

y = mx + b

32.13 = 1.65 x 17 + b

b = 1.14

The equation will be :

C(x) = 1.65x + 1.14

Now, To find the cost of using 19 HCF of water.

C(19) = 1.65 × 19 + 1.14

C(19) = $32.49

Hence, the cost of using 19 HCF of water is $32.49.

b) 68% percentage of people has an IQ score between 90 and 110.

c) 2.5% percentage of people has an IQ score greater than 120.

Step-by-step explanation:

The empirical formula states that:

The empirical rule is known as the three-sigma rule or 68-95-99.7 rule.
It is a rule which states that for a normal distribution, almost all data falls within three standard deviations of the mean.
68% of data falls within the first standard deviation that is $\mu \pm \sigma$
