according to a political polling firm, the probability of candidate a winning the Democratic primary is 60%. If she wins the Democratic primary, the probability of her winning the general election is 54%. What's the probability of her winning the Democratic primary and then general election?
Answer:
d) 32.4%
Step-by-step explanation:
p(chance of winning general election) = (chance of winning primary)x(chance of winning general) = 60% x 54% = 0.6 x 0.54 = 0.324 = 32.4%
will mark brainliest!! solve & simplify the following equation: 2x²-7x=4
Answer:
x= −1 /2 or x=4
Step-by-step explanation:
This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step
2x^2−7x=4
Step 1: Subtract 4 from both sides.
2x^2−7x−4 =4 −4
2x^2−7x−4=0
Step 2: Factor left side of equation.
(2x+1)(x−4)=0
Step 3: Set factors equal to 0.
2x+1=0 or x−4=0
x= −1 /2 or x=4
(BTW, there are supposed to be two answers, it's factoring)
Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

Step-by-step explanation:
determine the range of the function graphed above
Answer: A
Step-by-step explanation:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.
The possible values of y are [-infinity,4], so the answer is A
Sophia just graduated from college and is living on her own. She only wants to
spend about ten percent of her net income on food. She earns a net income of
$2,450 each month. Last week, she tracked her food spending and found she
spends about $75 a week on groceries. Is she meeting the ten percent?
Answer:
Sophia's monthly spent on food is $300 while she wants to spend $245.
As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month
Step-by-step explanation:
Net income of Sophia = $2,450
% of money she wants to spend on food = 10% of Net income of Sophia
thus,
Amount of money she wants to spend on food in $
= 10% of $2,450
= 10/100 * $2,450 = $245
Hence, Sophia wants to spend $245 in a month on food.
__________________________
it is given that last week she spent $75 on food
thus, weekly spent on food = $75
as there are 4 weeks in a months
money spent by her in 4 weeks = $75* 4 = $300
Thus, her monthly spent on food is $300 while she wants to spend $245.
As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month
What is the value of x in the equation 8x - 2y = 48, when y = 4?
Answer:
x = 7
Step-by-step explanation:
8x - 2y = 48
Let y=4
8x - 2(4) = 48
8x -8 = 48
Add 8 to each side
8x -8+8 = 48+8
8x = 56
8x/8 = 56/8
x = 7

How many gallons of paint will you need to paint a bedroom that is 10 ft by 14 ft with walls that are 7 1/2 ft high? The walls will need two coats to cover the old paint.
How many gallons of paint are needed to paint the ceiling of the same room in the last question, one coat of paint will suffice.
you have two walls that are 10 by 7.5 so 75 feet ^2 in area each
you have another two walls that are 14 by 7.5 so 105 feet^ 2 each
so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy
for the ceiling you do the same, the area is 140 and you only need one coat

Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?
Answer:
2000 ml of liquid
Step-by-step explanation:
1l plus 1l will equal 2l.
1 liter consists of 1000 milliliters ("milli" means thousand).
If 1l had 1000ml, 2l will have 2000ml.
So 2000mlnis the answer
A company pays each of its two office employees each Friday at the rate of $120 per day for a five-day week that begins on Monday. If the monthly accounting period ends on Tuesday and the employees worked on both Monday and Tuesday, the month-end adjusting entry to record the salaries earned but unpaid is:
Answer:
Debit Salaries Expense $480 and credit Salaries Payable $480
Step-by-step explanation:
Firstly, we will need to calculate the salary expense of the company on these two employees.
Mathematically, that would be
2 employees * 2 days * 120/employee/day = 2 * 2 * 120 = $480
Thus, the month-end adjusting entry to record the salaries earned but unpaid is that salaries expense will be debited $480 and salaries payable will be credited $480
A checkout clerk at a department store is expected to complete 16 transactions every hour. In the past 20 minutes, he completed 6 transactions. Choose True or False for each statement.
Answer:
False
Step-by-step explanation:
A checkout clerk at a department store is expected to complete 16 transactions every hour
I.e 16 transactions in 60 minutes
So if it's 6 transactions, let's check to know if the minutes Tally.
16 = 60
6 = (6*60)16
6 = 22.5 minutes
But in the statement it was 20 minutes, so the answer is false.
A basketball player's "hang time" is the amount of time the player remains suspended in the air after a jump. The height (in meters) of superstar Michael Jordan during a jump is shown in the graph below. Assume that hhh is the distance from the ground to the lowest part of his body at ttt seconds.. Complete the following sentences based on the graph of the function. Round your answers to the nearest tenth. This is the graph of a function. Michael Jordan's hang time is second(s). The maximum height is about meter(s) . For ttt between t=0.5t=0.5t, equals, 0, point, 5 and t=1t=1t, equals, 1, the height is .
Answer:
The graph is a nonlinear function. Michael Jordan's hang time is 0.9 seconds. The maximum height is about 1 meter. For t between t = 0.5 and t = 1, the height is decreasing.
Step-by-step explanation:
Okay the first one: It's nonlinear because its not a line, its a curve and its definitely not constant. The curve on the graph stops at (0.9,0) so his hangtime is 0.9 seconds. The peak of the curve is about 1 meter. Pretty self explanatory. And the last one, after the point 0.5, the height of the curve goes down, so it is decreasing.
Answer:
The graph is a nonlinear function
Michael Jordan's hang time is 0.9 seconds
The maximum height is about 1 meter
For t between t = 0.5 and t = 1, the height is decreasing.

A city's mean minimum daily temperature in February is 22 degrees Upper F. Suppose the standard deviation of the minimum temperature in February is 6 degrees Upper F and that the distribution of minimum temperatures in February is approximately Normal. What percentage of days in February has minimum temperatures below freezing left parenthesis 32 degrees Upper F right parenthesis?
Answer:
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )

A student is doing a reading assignment. After 37 minutes of reading, she skims the pages ahead and estimates that she still has 55% of the reading to do. According to the girl's estimate, how long is the total reading assignment? Round to the nearest minute.
Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.
[tex]\frac{37}{45}[/tex]
Multiply by 100 to find how much the whole time is: [tex]\frac{3700}{45}[/tex]
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
Answer:
82 mins
Step-by-step explanation:
percentage of pages she has already read
100-55= 45%
45%----------- 37mins
55%------------ x mins
x =( 37× 55)/45
x= 45.22 mins
approximately x=45 mins
The time for reading assignment is 37mins + 45 mins = 82 mins.
