Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15. what is her z score?
Andreas93 [3]

Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.

According to the given question.

Tobi scored 145 marks on an iq test.

⇒ x = 145

Mean, μ = 100

Standard deviation, σ = 15

As we know that,

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

And it is calculated by formula

Z = x -μ/σ

Where,

Z is a Z-score

μ is mean

x is the observed value

Therefore,

The Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15

= 145 - 100/15  

= 3

Hence,Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.

Yao Xin puts 3/10 liters of potting soil in each pot for planting flowers. She has 5 2/3 liters of potting soil. How many pots c
Korvikt [17]

Answer:

18 8/9 pots

Step-by-step explanation:

Total potting soil = 5 2/3 liters

Potting soil per pot = 3/10 liters

How many pots can Yao Xin fill?

Number of pots Yao Xin can fill = Total potting soil / Potting soil per pot

= 5 2/3 liters ÷ 3/10 liters

= 17/3 ÷ 3/10

= 17/3 × 10/3

= (17*10) / (3*3)

= 170/9

= 18 8/9

Number of pots Yao Xin can fill = 18 8/9 pots
