Answer:

Pia

Step-by-step explanation:

The smaller the number of pencils in a bundle the greater the number of bundles.

For example if the number of pencils each has is 60,

Then the number of bundles for Pia = 60/10 = 6,

and ...................................................Gauri = 60/12 = 5,

and .....................................................Yasmin = 60/20 = 3.

A data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66

blondinia [14]

Answer:

The 99% confidence intervals are

(98.4346 , 98.7654)

C) This suggests that the mean body temperature could very possibly be 98.6degrees°F.

Step-by-step explanation:

Given data a data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66degreesF

sample size n = 106

Mean of the population ' μ' = 98.7degreesF

standard deviation of population 'σ' = 0.66degreesF

Mean of the sample x⁻ = 98.6degreesF

Level of significance ∝ = 0.99 0r 0.01

Confidence limits :-

The values $(x^{-} - 2.58\frac{S.D}{\sqrt{n} } ,x^{-} +2.58\frac{S.D}{\sqrt{n} } )$ are called 99% of confidence limits

For the mean of the Population corresponding to the given sample.

$(98.6 - 2.58\frac{0.66}{\sqrt{106} } ,98.6 +2.58\frac{0.66}{\sqrt{106} } )$

on calculation, we get

(98.6 - 0.1654,98.6 + 0.1654)

The 99% confidence intervals are

(98.4346 , 98.7654)

C) This suggests that the mean body temperature could very possibly be 98.6degrees°F.

↓can somone answer this for 10 points↓

Gekata [30.6K]

Answer:

15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13

Step-by-step explanation:

When the seats are empty, there are a total of 15 people that can possibly sit in there. There will only be 1 person left.

When the 1st seat is taken there are now 14 people who can possibly sit on another chair. Same goes when 2 seaats are taken.

To find the total number of possibilities, we multiply together the possible number of people for seat 1, seat2, and seat 3.

Or, if we use stat, nPr = n! / (n-r)!

Meaning:

15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13

Simora [160]

Answer:

x is less than or equal to 16

Step-by-step explanation:

- 2 x x + 4 < 20

Isolate the variable

divide 2 from 2 = 0

x + 4 < 20

x is less than or equal to 16
