Answer:

1−0.03125=0.96875

Step-by-step explanation:

The probability of having a male or female child is equal (0.5).

So having your first child means you have a 50% chance of a male. Your second child being male also will have a probability of

0.5x0.5=0.25 .

The only scenario in which a couple with five children do not have at least one son is if all five children are female.

So the pribability of having five females is  0.55=0.03125  

So if every other scenario means the couple have at least one son, and the total probability of an event is 1, we can find the probability of having at least one son with

1−0.03125=0.96875

Write the equation of the line, in slope intercept form, through the following points:
lakkis [162]

Hey!

------------------------------------------------

First, find the slope.

y2-y1/x2-x1

-20-(-5)/21-16

-15/5

-3

------------------------------------------------

Second, find the y-intercept.

We can solve for b with one of the points.

Put into slope-intercept form,

y = -3x + b

Substitute x and y with (16, -5)

-5 = -3(16) + b

-5 = -48 + b

-5 + 48 = -48 + b + 48

43 = b

------------------------------------------------

Third, put in slope-intercept form.

y = mx + b

m = slope

b = y-intercept

y = -3x + 43

------------------------------------------------

Hope This Helped! Good Luck!

Students were surveyed about their preference between dogs and cats. The following two-way table displays data for the sample of
goldfiish [28.3K]

Answer:

48/100=48%

the girls who responded to the survey.

Step-by-step explanation:

To find the answer, you would put the total number of boys over the total number of kids who responded to the survey since the question wanted to know what percentage of all the kids were boys. Since the denominator is already 100, we can immediately say that the numerator, or 48, is the percentage of boys who took the survey. The other 52% of the kids were the girls who responded to the survey.

One custodian cleans a suite of offices in 3 hours. When a second worker is asked to join the regular custodian, the job takes o
katen-ka-za [31]

Answer:

  6 hours

Step-by-step explanation:

Let x represent the time in hours it takes the second worker to do the job alone. Then each hour, 1/x of the job gets done by that worker. Similarly, the regular custodian accomplishes 1/3 of the job in each hour. Working together, they do 1/2 of the job each hour:

  1/3 +1/x = 1/2

  1/x = 1/2 -1/3 = 3/6 -2/6 = 1/6 . . . . subtract 1/3 and simplify

  x = 6

It takes the second worker 6 hours to do the same job alone.
