Answer:

'<' (lessthan symbol) and '/' (division symbol) are the two operations needed here to represent the given expression

In the expression $5$ we are using the '<' (lessthan symbol) and '/' (division symbol)

The expression that represents “five less than the quotient of a number and three” is $5$

Step-by-step explanation:

Given that “five less than the quotient of a number and three”

To find the two operations that are needed to write the given expression :

Let x be the number

“five less than the quotient of a number and three”

can be written as below

$5$

Therefore “five less than the quotient of a number and three”= $5$

The expression that represents “five less than the quotient of a number and three” is $5$

In the expression $5$ we are using the '<' (lessthan symbol) and '/' (division symbol)

'<' (lessthan symbol) and '/' (division symbol) are the two operations needed here to represent the given expression

The distribution of scores on a recent test closely followed a Normal Distribution with a mean of 22 points and a standard devia

maksim [4K]

6.68% of the students scored at least 19 points on this test while the 85 percentile has a test score of 24.08 points

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=22,standard \ deviation (\sigma)=2\\\\For\ x>19:\\\\z=\frac{22-19}{2}=1.5$

P(x > 19) = P(z > 1.5) = 1 - P(z < 1.5) = 1 - 0.9332 = 0.0668

6.68% of the students scored at least 19 points on this test

b) 85 percentile corresponds to a z score of 1.04

$z=\frac{x-\mu}{\sigma}\\\\1.04 =\frac{x-22}{2} \\\\2.08=x-22\\\\x=24.08$

The 85 percentile has a test score of 24.08

Answer:

-5 5/10, -32/40,5

whenever a number has a negative sign,the larger the number the smaller.

i.e (-55/10= -5.5) is smaller than -32/40=-0.8 and then the greatest is 5 since it is a positive number and positive numbers are greater than negative numbers.

Each person on a four-person relay team completed a race in approximately 18.1 seconds. How long did it take the relay team to f

likoan [24]

Answer:

72.4 seconds

Step-by-step explanation:

We are given that,

Time taken by each person in the team = 18.1 seconds

Number of members in the team = 4

It is required to find the total time taken by the team to finish the race.

Thus, the time taken taken = 4 × 18.1 = 72.4 seconds

Hence. the team finished the race in 72.4 seconds.

Hello,

x² + 5x + 6 = 0

a = 1 ; b = 5 ; c = 6

∆ = b² - 4ac = 5² - 4 × 1 × 6 = 25 - 24 = 1 > 0

2 solutions :

$x_{1} = \frac{ - b - \sqrt{\Delta} }{2a} = \frac{ - 5 - 1}{2 \times 1} = \frac{ - 6}{2} = - 3$

$x_{2} = \frac{ - b + \sqrt{\Delta} }{2a} = \frac{ - 5 + 1}{2 \times 1} = \frac{ - 4}{2} = - 2$
