Amy raises $58.75 to participate in a walk-a-thon. Jeremy raises $23.25 more than Amy. Oscar raises 3 times as much as Jeremy. How much money does Oscar raise
Answer:
oscar raises 246 dollars.
Step-by-step explanation:
you add 23.25 to amys amount and then times that by 3 to find the answer.
Answer:
I think its 246
Step-by-step explanation:
if you add 58.75 to 23.25 you get you get 82 and when you multiply by 3 you get 246
Suppose that 84% of the cases of car burglar alarms that go off are false. Let p be the proportion of false alarms in a random sample of 110 cases of car burglar alarms that go off. Calculate the mean and standard deviation of p and describe the shape of its sampling distribution.
Round your answer to four decimals places if necessary
up= ______
op= ______
The sampling distribution of p is normal or skewed to the right?
Answer:
0.84 ; 0.0349545 ; symmetric
Step-by-step explanation:
Given that:
p = proportion of false alarm
Sample size (n) = 110
The mean of p
Since 84% of car buglar alarms turns out as false, then, the mean value of p = 0.84
To obtain the standard deviation ; we use the relation ;
√(p(1 - p) / n)
Standard deviation :
√0.84(1 - 0.84) / 110
√0.84(0.16) / 110
√0.1344 / 110
√0.0012218
= 0.0349545
np = 110 * 0.84 = 92.4 (distribution is symmetric or normal)

Lin ran 2 ¾ miles in ⅖ of an hour. Noah ran 8 ⅔ miles in 4/3 of an hour.
Who ran faster, Noah or Lin?
How far would Lin run in 1 hour?
How far did Noah run in 1 hour?
How long would it take Lin to run 1 mile at that rate?
How long would it take Noah to run 1 mile at that rate?
Lin ran faster because if you convert 2/5=24mins 4/3=80mins and lin would run 2.5 miles in an hour and Noah would run 0.75 miles

If triangle PQR is plotted, it will have the following coordinates,P(-4,0),Q(4,2)and R(-2,4). If point R is translated 4 units right and 7, what are the coordinates of R'?
Answer:
(2, -3)
Step-by-step explanation:
Right now, R is at (-2, 4). If it is pushed 4 units to the right, it becomes -2+4 = 2 on the x-axis. If it is pushed 7 units down, it becomes 4-7 = -3. Thus, the coordinates are (2, -3)
A triangle has vertices A(-3,6), B(-3, 4), and C(3,4).
If the triangle is translated 2 units to the right and 1 unit down, what will be the new coordinates of vertex A?
Answer:
(-1, 5)
Step-by-step explanation:
Right now, A is at (-3, 6). If it is pushed 2 units to the right, it becomes -3+2 = -1 on the x-axis. If it is pushed 1 unit down, it becomes 6-1 = 5. Thus, the coordinates are (-1, 5)
y=-3/4x-2 convert into standard form (clear fraction)
Answer:
3x+4y=-8

Answer:
The equation that represents the relation between the figure number, x, and the number of the tiles, y is y = 2x + 1
Step-by-step explanation:
The slope-intercept form of the equation is y = m x + b, where
m is the slope ⇒ constant rate of changeb is the y-interceptIn the given pattern
∵ x represents the figure number
∵ y represents the number of tiles
∵ At x = 1, y = 3
∵ At x = 2, y = 5
∵ At x = 3, y = 7
∵ 5 - 3 = 2 and 7 - 5 = 2
→ That means the constant rate of change is 2
∴ m = 2
→ Substitute it in the form of the equation above
∴ y = 2x + b
→ To find b substitute x and y by the first figure
∵ x = 1 and y = 3
∴ 3 = 2(1) + b
∴ 3 = 2 + b
→ Subtract 2 from both sides to find b
∴ 3 - 2 = 2 - 2 + b
∴ 1 = b
→ Substitute it in the equation
∴ y = 2x + 1
The equation that represents the relation between the figure number, x, and the number of the tiles, y is y = 2x + 1
Bella had already read 20% of the book before her teacher assigned it to the class. She is choosing between two options to finish reading the book
. option 1: read 25% of the reminding pages each night
. option 2: read 24 pages each night
which option should bella use to finish the book in the least amount of time ?
Answer:
How big is the book?
If it has more than 96 pages remaining 25% each night is quicker if it has less that 96 or less remaining 24 pages a night is faster
Step-by-step explanation:
So let's say that there are 100 pages of the book Bella is reading. With this information, because she read 20% of the book, there is still 80% left.
Let's look at option 1: read 25% each night. Because 25% of 80 is 20, this would mean Bella would have to read 20 pages each night.
Let's look at option 2: read 24 pages each night.
With this information, we can already tell which option is going to get Bella to read the book faster.
Answer: Option 2.

Median for 5,8,10,1,7,6,15,8,6
Answer: 7
Step-by-step explanation: How I Got 7 is the median is the middle number of the data table so the median is always the middle number of the equation Hope This Helps ;)
The median is the middle number in a set of ordered numbers.
So let's first write our data set from least to greatest.
1, 5, 6, 6, 7, 8, 8, 10, 15
Since the 7 appears in the middle, it's our median.

Answer:
30936.903999
Step-by-step explanation:
Answer:
They will make 28478.88
Step-by-step explanation:
First you multiply 12 by 4 because there is 12 months in a year and there is 4 weeks in one month. So next you will multiply 48 (that’s what 14 by 4 is), by 593.31. And you get 28478.88

Answer:
[tex]\frac{22}{12}[/tex] = [tex]\frac{x}{10}[/tex]
Step-by-step explanation:
ΔUSA ≅ ΔPAL
[tex]\frac{AU}{AP}[/tex] = [tex]\frac{US}{PL}[/tex]
[tex]\frac{22}{12}[/tex] = [tex]\frac{x}{10}[/tex]
x = [tex]\frac{220}{12}[/tex] = [tex]\frac{55}{3}[/tex] = [tex]18\frac{1}{3}[/tex]
