If 3 people can complete half of a job in 20 days, how long would it take for 12 people to do the complete job?
Answer:
If 3 people can complete half a job in 20 days, then three people can complete a job in 40 days. Since 12 people is four times as many, instead of taking 40 days, it should take 10 days

Answer:
Step-by-step explanation:
5. You are asked to write an equation of the line in slope-intercept form, so you need to determine the slope of the line and the y-intercept.
You're lucky. One of the points, (0,1), has an x-coordinate of 0, so you know that the y-intercept is 1.
Use the coordinates of the points to determine the slope of the line.
slope = (difference in y-coordinates)/(difference in x-coordinates) = (10-1)/(3-0) = 9/3 = 3
The slope-intercept equation of the line is y = 3x+1
:::::
7. When x = 0, function A = 0 and function B = 3, so function B has a greater initial value.
the standard form of the equation through the points (-2,-2) and (2,-1)
Answer:
y = 1/4x - 3/2
Step-by-step explanation:
for slope, use formula (y2-y1)/(x2-x1):
(-1-(-2))/(2-(-2))
=1/4
use formula y=mx+b for equation:
y=1/4x+b (substitute x and y for either (-2, -2) or (2, -1))
-1=1/4(2)+b
-1=1/2+b
-3/2 = b
equation:
y = 1/4x - 3/2

13 percent of a certain company's life insurance policy holders are smokers. For each nonsmoker the probability of dying during the year is 0.002. For each smoker the probability of dying during the year is 0.02. Find the probability that a policy holder who died last year was a smoker.
Answer:
.6
Step-by-step explanation:
Using Bayes' theorem
While s = smoker
n = nonsmoker
D = died
P(s) = .13
P(n) =.87
P(D/s) =0.02
P(D/n) =0.002
P(s/D) = ??
[tex]P(s/D)=\frac{P(s)*P(D/s)}{P(s)*P(D/s)+P(n) *P(D/n)} =\frac{.13*.02}{.13*.02+.87*.002}=.6[/tex]

A car travels 208 miles in 3 hours and 15 minutes. How many miles does it travel per hour?
Answer:
64 miles
Step-by-step explanation:
3 hours and 15 minutes = 3.25 hours (since 15 minutes is a quarter of an hour)
so 208 miles in 3.25 hours can be written as
208 miles / 3.25 hrs = 208/3.25 miles/hrs (or miles per hour)
=64 miles per hour

Answer:
Hence, first one will be 1/3 and second one will be 1/6
Step-by-step explanation:
1. Let the blank space be x then,
[tex]3 \frac{2}{3} + x = 4[/tex]
[tex]x = 4 - 3 \frac{2}{3} [/tex]
[tex]x = \frac{12 - 11}{3} [/tex]
[tex]x = \frac{1}{3} [/tex]
2. Let the blank be x then,
[tex]x + \frac{2}{3} = \frac{5}{6} [/tex]
[tex]x = \frac{5}{6} - \frac{2}{3} [/tex]
[tex]x = \frac{5 - 4}{6} [/tex]
[tex]x = \frac{1}{6} [/tex]

Solve the inequality 5 - 4x > -x+8
Answer:
x<-1
Step-by-step explanation:
5-4x>-x+8
adding 4x to both sides we get
5>3x+8
subtracting eight from both sides we get
-3>3x
dividing by three on both sides we get
-1>x
or x<-1

2x + y = 7
-2x - y = 6
Solve systems of equations by substitution
Answer:
No solution.
Step-by-step explanation:
2x + y = 7
-2x - y = 6
From the first equation:
y = 7 - 2x
Plug this into the second equation:
-2x - (7 - 2x) = 6
-2x + 2x = 6 + 7
0 = 13
this doesn't make sense so theer is:
No solution.

Sally has 21 books sam has 24 time books than Sally how many books does Sam have
Can you delete my comment? I made a mistake-
Sally's books = 21
Sam's books
= 24 times Sally's books
= 24 times 21
= 24 × 21

How many real-number solutions does the equation have? - 7x2 + 6x + 3 = 0
Answer:
How many real-number solutions does the equation have? - 7x2 + 6x + 3 = 0
Step-by-step explanation:
a. B^2-4AC = 36-(-84) = 120.
The discriminant is positive. Therefore, we have 2 real solutions.
b. B^2-4AC = 324-324 = 0. 1 real solution.
