The weights of packs of chewing gum for a certain brand have a mean of 47.1 grams and a standard deviation 2.4
Verdich [7]

A Z-score helps us to understand how far is the data from the mean. The correct option is B.

<h3>What is Z-score?</h3>

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

Z = \dfrac{X- \mu}{\sigma}

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The weight of a randomly selected pack of gum has a z-score of 3.11. Therefore, The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.

Hence, the correct option is B.

3- There are 35 cubes in 7 bowls. How many cubes in 3 bowls?
Murrr4er [49]

Answer:

3. 15 Cubes

4. 60 ft per sec , 180 ft

5. 58 yards per min

6. $7.50, $18.00

Step-by-step explanation:

3. Number of Cubes in 7 bowls = 35

Number of Cubes in 1 bowls = \frac{35}{7}

Number of Cubes in 3 bowls =\frac{35}{7} \times 3 = 15

4. Distance ran by Zebra = 420 ft

Time taken = 7 seconds

Speed = \frac{Distance}{time}= \frac{420}{7}=60 ft per sec

Hence

Distance = speed x time

Distance covered in 30 seconds = 60 x 30 = 180 Ft

5. Distance travelled = 870 yards

Time taken = 15 mins

Speed =\frac{Distance}{time}= \frac{870}{15}=58 yards per min

6. Cost of 3 pounds of apple = $4.50

Cost of 1 pounds of apple = \frac{4.50}{3}=$1.50

Cost of 5 pounds of apple = 5 x $1.50 =$7.50

Cost of 12 pounds of apple = 12 x $1.50 =$18.00

NEED HELP!!!!!!!!!!! NO LINKS!!!!!!!
omeli [17]

Answer:

3x=18

Step-by-step explanation:

We want to get the variable x by itself.

Since we see a -3 with the 3x, we want to move the 3 to the other side of the equal sign by adding 3 to both sides of the equal sign.

3x - 3 = 15

3x - 3 + 3 = 15 + 3

Then we get:

3x + 0 = 18

3x = 18
