a) P) 0.25 = 1/4 both
b) P) 0.75 = 3/4 one
c) P) 0.25 = 1/4 none
Step-by-step explanation:
4 routes to D + H
6 routes to H + S
= D H S
4 | 6
- 2 | -3
= 2 | 3 = route 1 = 2/4 and route 2 = 3/6
= 1/2 route 1 and 1/2 route 2
Answer a ) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability
Answer b) = 1- (1/2 x 1/2) = 1- 0.25 = 3/4 = 0.75 probability
Answer c) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability

Answer:
x = -8, x =0 and x =6
Step-by-step explanation:
f(x) = 0 means when it crosses the x axis or when y = 0
There are 3 places when it crosses the x axis
x = -8, x =0 and x =6

Angel signed up for a streaming music service
that costs $11 per month. The service allows
Angel to listen to unlimited music, but if he
wants to download songs for offline listening, the
service charges $0.50 per song. How much total
money would Angel have to pay in a month in
which he downloaded 25 songs? How much
would he have to pay if he downloaded s songs?
Answer:
Cost for 25 songs: $23.50
Cost for s songs: .50(s) + 11
Step-by-step explanation:
To solve this problem, we can make an equation in slope-intercept form:
y = mx + b
y represents the total amount of $.
m represents the cost of each song downloaded, or $.50
x represents the number of songs, or 's'
b represents the $11, or the constant.
We have the equation:
y = .50(x) + 11
If Angel downloaded 25 songs, we have the equation:
y = .50(25) + 11
We get y = $23.50

- 3/7 m = 12
m = -28
m = -26
m = 26
m = 28
Answer:
[tex]m = - 28[/tex]
Step-by-step explanation:
[tex] \frac{ - 3}{7} m = 12[/tex]
[tex] \frac{ - 7}{3} ( \frac{ - 3}{7})m = \frac{ - 7}{3} \times 12[/tex]
[tex] \frac{ - 1}{3} ( - 3)m = \frac{ - 7}{3} \times 12[/tex]
[tex] - 1( - 1)m = \frac{ - 7}{3} \times 12[/tex]
[tex]1 \times m = \frac{ - 7}{3} \times 12[/tex]
[tex]m = \frac{ - 7}{3} \times 12[/tex]
[tex]m = \frac{ - 7}{3} \times 12[/tex]
[tex]m = \frac{ - 7}{3} (3 \times 4)[/tex]
[tex]m = - 28[/tex]
Hope it is helpful....How much work is done lifting a 35 pound object from the ground to the top of a 25 foot building if the cable used weighs 2.5 pounds per foot
Answer:
3400 ft-lbs
Step-by-step explanation:
The Workdone in lifting the rope :
Number of feet = x
Distance = 25 feets
2.5x + 35
Taking the integral :
∫2.5x + 35 dx at x = 40
Integrating, we have :
1/2(2.5x² ) + 35x at x = 40
1/2(2.5(40)²) + 35(40)
1/2(4000) + 1400
2000 + 1400
= 3400
Hence, Workdone in lifting the rope = 3400 ft-lbs

A survey of 200 families showed that
75 had a dog;
58 had a cat;
25 had a dog and a cat;
77 had neither a cat nor a dog nor a parakeet;
5 had a cat and dog and a parakeet.
How many had a parakeet only?
Answer:
15 is the answer , the total people who has dogs , cats , parakeets and none is equals to 185 then from 200 you minus 185 which is 15 so 15 people had parakeets only
the sum of two numbers is 37 and the greater number is 5 less than twice the Lesser number find the positive intergers
Answer:
x = 14
y = 23
Step-by-step explanation:
x = first number
y = second and greater number
x + y = 37 ⇒ y = 37 - x
y + 5 = 2x
Substitution:
(37 - x) + 5 = 2x
42 - x = 2x
3x = 42
x = 14
y = 37 - (14)
y = 23
f(x) = 3x + 4 is y =

Line p passes through points (5,-4) and (2,7). What is the slope of a line that is perpendicular to line p
Answer:
3/11
Step-by-step explanation:
First find the slope of the line
m = (y2-y1)/(x2-x1)
= ( 7 - -4)/(2 - 5)
= (7+4)/(2-5)
=11/ -3
We want a line that is perpendicular, so it is the negative reciprocal
-1 / ( -11/3)
+3/11
A line that is perpendicular will have a slope that is 3/11

does anyone know w(t) = 3t - 1, w(-4.2) ?
Answer:
w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6
Step-by-step explanation:
The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of bolts. The sample mean bolt length was centimeters. The population standard deviation is known to be centimeters.
What is the test statistic z?What is the p-value?Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?
Answer:
There is sufficient evidence. A further explanation is provided below.
Step-by-step explanation:
According to the question,
The alternative as well as null hypothesis will be:
[tex]H_0:\mu = 16[/tex]
[tex]H_a:\mu>16[/tex]
The test statistics will be:
⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]
By putting the values, we get
⇒ [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=2.45[/tex]
Or,
The p-value will be:
= 0.0071
i.e.,
⇒ [tex]p-value< \alpha[/tex]
Thus the above is the correct answer.

Kendall is starting a new small business and working everyday to make it a success. She earned $952 in 7 days. Assume she will continue to earn money as the same rate and write this rate as a fraction with 30 in the denominator.
Answer:
$4080 / 30days
Step-by-step explanation:
In 7 days, Kendall earns $952
In 1 day, she will earn $952 ÷ 7 = $136
Therefore, the rate (r) at which she earns is $136/day. i.e
r = $136/day ---------------(i)
To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;
r = $(136x30) / 30 day
r = $4080/30days
