Answer:

sample mean (x with the bar on top) =24

Step-by-step explanation:

Take the mean of all the number of employees but divide by the number of days size: (25+10+16...)/12=25

population mean (mu) =11.52

The same goes for the other one but divide by the population which is 25

Answer:

It should be y = -x + r or y = r - x. To solve for y you would have to isolate y by removing all other variables from y's side of the equation.

x=3

Step-by-step explanation:

Secant-Secant Formula:(whole secant) x (external part) =

       (whole secant) x (external part)

4 *(9) = x *(12)

Answer:

It takes 4.75 hours(4 hours and 45 minutes) to travel 247 miles.

Step-by-step explanation:

This question is solved by rates, using a rule of three.

52 miles in one hour. How many hours for 247 miles?

1 hour - 52 miles

x hours - 247 miles

Applying cross multiplication:

[tex]52x = 247[/tex]

[tex]x = \frac{247}{52}[/tex]

[tex]x = 4.75[/tex]

It takes 4.75 hours = 4 hours and 3/4*60 = 45 minutes to travel 247 miles.

Answer:

A=14 and B= 8

Step-by-step explanation:

the equation systems:

150A + 225B = 3900

=> 6A + 9B= 156 .... (1)

A + B = 22 ..... (2)

<=> 6A + 9B = 156

6A + 6B = 132

_____________-

3B = 24

B= 8 and A = 22-8 = 14

3x12 = 36

Answer:

Step-by-step explanation:

all the fruits are 10

the pears are 3

probability of picking a pear is 3/10

out of 120 times the pear may be picked 120*(3/10) = 36 times

Step-by-step explanation:

"Best estimate' doesn't happen automaticallly, because you have to define "best" in this context.  We could merely round all numbers and work with the results:  

For example, starting with the work inside parentheses, we have:

5 5/6 - (1 + 4) = 5 5/6 - 5.  We must round 5 5/6 up to 6.  Then the "best estimate' is 6 - 5, or just 1.

The solution of the given expression is 17 / 24.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression is 5⁵/₆ - (1¹/₄ + 3⁷/₈)​. The value of the expression will be calculated as:-

E =  5⁵/₆ - (1¹/₄ + 3⁷/₈)

E = 35 / 6 - [ 5 / 4 - 34 / 8 ]

E = 35 / 6 - [ ( 10 + 31 ) / 8 ]

E = 35 / 6 - 41 / 8

E = ( 140 - 123 ) / 8

E = 17 / 21

Hence, the solution of the expression is 17 / 21.

Answer:

LCM of 64 and 94= 3008

HCF of 64 and 94= 2

Step-by-step explanation:

Do a venn diagram with the prime factors of 64 on the left, and the prime factors of 94 on the right. If they have the same factors put them in the middle of the venn diagram. Then you multiply everything in the diagram and get the LCM. The HCF is found by multiplying the factors in both lists which is only 2.

The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

in a group of 35 children, 10 have blonde hair, 14 have brown eyes, and 4 have both blonde hair and brown eyes.

let, the event be A,

i.e. A = if a child is selected at random, that child has blonde hair or brown eyes.

now, we have,

total no of sample space = 35

probability of blonde hair = 10/ 35

probability of brown eyes = 14/35

probability of both blonde hair and brown eyes = 4/35

so, we get,

probability of  blonde hair or brown eyes = 14/ 35 + 10/ 35 - 4/35

                                                                    = 20 / 35

                                                                    = 4/7

Hence, The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.

The required percentage of individuals is 66.07%.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

The required data from the given table is as follows,

The total number of individuals is 112.

The number of individuals who ride Ferris wheel but not roller coaster is 74.

As per the question the percentage can be found as below,

Required percent = (The required number ÷ Total number) × 100

                              = (74 ÷ 112) × 100%

                               = 66.07%

Hence, the percentage of the individuals rode the Ferris wheel and did not ride the roller coaster is  66.07%.
