Answer:

C: A line travelling to the right with an open dot on p = -3.

Step-by-step explanation:

You use a closed dot when the equation is greater/less than or equal to: $\geq \leq$

It goes right because if it went left it would be p < -3.

Use compatible numbers to find two estimates that the quotient is in between 1,189 divided by 4

Molodets [167]

Answer:

297 and 298

Step-by-step explanation:

We are given a number 1189.

We have to divide this number by 4 and find the quotient that is the two estimates between which the quotient lies.

By rule for divisibility of 4, we have last two digits 8 and 9 , i.e.89 is not divisible by 4.

Hence 1189 is not divisible by 4.

But the greatest below number divisible by 4 is 1188 and

the least above number divisible by 4 is 1192

i.e. the quotients will lie between 1188/4 and 1192/4

i.e. lie between 297 and 298.

Answer:

a) A response of 8.9 represents the 92nd percentile.

b) A response of 6.6 represents the 62nd percentile.

c) A response of 4.4 represents the first quartile.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 5.9

Standard Deviation, σ = 2.2

We assume that the distribution of response is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) We have to find the value of x such that the probability is 0.92

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 5.9}{2.2})=0.92$

Calculation the value from standard normal z table, we have,

$P(z$

$\displaystyle\frac{x - 5.9}{2.2} = 1.405\\x = 8.991 \approx 8.9$

A response of 8.9 represents the 92nd percentile.

b) We have to find the value of x such that the probability is 0.62

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 5.9}{2.2})=0.62$

Calculation the value from standard normal z table, we have,

$P(z$

$\displaystyle\frac{x - 5.9}{2.2} = 0.305\\x = 6.571 \approx 6.6$

A response of 6.6 represents the 62nd percentile.

c) We have to find the value of x such that the probability is 0.25

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 5.9}{2.2})=0.25$

Calculation the value from standard normal z table, we have,

$P(z$

$\displaystyle\frac{x - 5.9}{2.2} = -0.674\\x = 4.4172 \approx 4.4$

A response of 4.4 represents the first quartile.

using what you know about percents,explain why a commercial that says"80% of dentists use this toothpaste"might be misleading?

weqwewe [10]

There are many dentists in the world and it wold be hard to count the amount of dentists that use the toothpaste. Also, there are many brands of toothpaste and it would would be doubtful that “80%” of dentists would use the same one.
