serious [3.7K]

Answer:

Sara expect the better grade for Math class.

Step-by-step explanation:  

Consider the provided information.

On the Math exam, the mean was µ = 30 with s = 5, and Sarah had a score of X = 45.

Z score for Math: Z=\frac{x-\mu}{s}

Z=\frac{45-30}{5}

Z=\frac{15}{5}

Z=3

On the Spanish exam, the mean was µ = 60 with s = 8 and Sarah had a score of X = 68.

Z score for Spanish: Z=\frac{x-\mu}{s}

Z=\frac{68-60}{8}

Z=\frac{8}{8}

Z=1

On the English exam, the mean was µ = 70 with s = 8 and Sarah had a score of X = 70.

Z score for English: Z=\frac{x-\mu}{s}

Z=\frac{70-70}{8}

Z=0

We can observe that Z score of Math is greater than Spanish and English.

Which means that Sarah did the best in her Math exam.

Hence, Sara expect the better grade for Math class.

The density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. Express this density in p
Vadim26 [7]

Answer:

1.641× 10^-3 pounds/ cubic inch

Step-by-step explanation:

Density= mass / volume

Mass of the material= 9 kilograms

Volume= 7 cubic feet

Density= 9/7= 1.286 kg/ ft^3

Density= 1.286 kg/ ft^3

To Convert to pounds per inch

1 kg/ ft^3 = 0.00128 pound / cubic inch

1.286 kg/ ft^3 = X pounds/ cubic inch

X=( 1.286 × 0.00128)

= 0.0016407087 pounds/ cubic inch

= 1.641× 10^-3 pounds/ cubic inch

Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch
