Answer: 13
Step-by-step explanation:
The distance formula between two points is:
[tex]c = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Our points are as follows -
[tex]x_2 = 0, x_1 = 5\\y_2 = 8, y_1 = -4[/tex]
If we plug them in:
[tex]c = \sqrt{(0 - 5)^2 + (8 - (-4))^2}[/tex]
All we need to do now is simplify
[tex]c = \sqrt{(-5)^2 + (12)^2}[/tex]
[tex]c = \sqrt{25 + 144}[/tex]
[tex]c = \sqrt{169} = 13[/tex]

Zoé compró 3 quesos de 3/5 cada uno. ¿cuántos Kilogramos de queso tiene en total?
Answer:
W = 1.8 kg
Step-by-step explanation:
Zoé bought 3 cheeses, 3/5 each. How many Kilograms of cheese does he have in total?
Weight of each cheese is 3/5 kg. Zoe bought 3 cheeses. We need to find the weight of cheese in total.
To find weight of 3 cheeses, we will multiply 3 by 3/5 such that:
[tex]W=3\times \dfrac{3}{5}\\\\W=1.8\ kg[/tex]
So, the weight of cheese in total is 1.8 kg.
How do I solve this equation? -6=b/18 and v-15-=-27
Answer:
-6 = b/18
-6×18=b
-108 = b ans.
and
v-15- = -27
v = -27 +15
v = -12 ans.
A restaurant owner mixed the juices of 7 lemons with every 3 oranges to make a special drink
Which ratio of lemons to oranges will make the same drink?
a:28:15
b:42:21
c:21:9
d:15:35
Answer:
C, 21:19
Step-by-step explanation:
This is because we know that 21 divided by 7 is 3, so we would have to make sure that we are multiplying 7:3 by 3, which we are because 7 times 3 = 21 and 3 times 3 = 9.

Step-by-step explanation:
Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Complete the following payroll register. (Use the percentage method to calculate FIT for this weekly period
Marital status - m
Allowance claimed – 4
Gross pay - $,2800
FIT
Social Security
Medicare
Net pay
Answer:
FIT: $340.76 (see comment)OASDI: $173.60Medicare: $40.60Net Pay: $2245.04Step-by-step explanation:
In addition to the information given in the problem statement, we need to know the applicable tax rates and allowance deductions. If we assume the tables we found (attachments 1 and 2) are the same as those in your text, the one additional fact needed is the gross pay to date. At the given wage rate, paychecks after the 44th week will have reduced FICA tax deductions.
Allowances: 4 × $79.80 = $319.20
Adjusted gross pay for FIT: $2800 -319.20 ≈ $2481 (rounded to nearest $)*
FIT: 0.22 × (2481 -1711) +171.36 = 0.22×2481 -205.06 = 340.76
Social Security & Medicare: 0.0765 × 2800 = 214.20
Net pay = $2800 -340.76 -214.20 = $2245.04
_____
* Comment on rounding
The IRS gives the option of rounding the pay or the tax, as long as it is consistently done. Here, the amount of tax on the unrounded gross pay would be 4 cents less: 340.72. The option of reducing the last digit of pay to zero is also offered. FIT on 2480 would be 340.54.
plz help me will give brainlyest
Answer:
1. x = independent variable: Age
y = dependent variable: Accidents
2. Age scale and Accidents scale
The scale for age ranges from 15 - 30 with the value of 5 difference between each number.
While the accidents scale ranges from 0 -1 with no difference in between.
3. In my opinion, the scatter plot looks as though it decreases in accidents once the age rises. As seen from the data shown.
Step-by-step explanation:
1) x is considered as the independent variable, while y is considered the dependent value.
2) There are two sets of scales, one for the x and the other for y. These scales are the values that are interpreted in order to show data of the graph, due to their number and various size(s).
3) If you were to draw a line through the graph, you can somewhat create the image that the line would go down into the right corner! Meaning that it is decreasing over time.

-2.94
Step-by-step explanation:
2. The service life of a battery used in a cardiac pacemaker is assumed to be normally distributed. A random sample of ten batteries is subjected to an accelerated life test by running them continuously at an elevated temperature until failure, and the follow ing lifetimes (in hours) are obtained: 25.5, 26.1, 26.8, 23.2, 24.2, 28.4, 25.0, 27.8, 27.3, and 25.7. a. The manufacturer wants to be certain that the mean battery life exceeds 25 h. What conclusions can be drawn from these data (use a= 0.05)? b. Construct a 90% two-sided confidence interval on mean life in the accelerated test.
Answer:
Kindly check explanation
Step-by-step explanation:
Assuming a normal distribution :
Sample (x) :25.5, 26.1, 26.8, 23.2, 24.2, 28.4, 25.0, 27.8, 27.3, 25.7
Null hypothesis : μ = 25
Alternative hypothesis : μ > 25
α = 0.05
Decision region :
Reject Null if :
t0 > t
t can be obtained from the t distribution table at : df = (n - 1) = 10 - 1 = 9 ; α = 0.05
Hence, t(0.05, 9) = 1.833
From the sample given ; t0
t0 = (m - μ) / (s /√n)
n = sample size = 10
s = sample standard deviation
m = sample mean
Using calculator :
25.5, 26.1, 26.8, 23.2, 24.2, 28.4, 25.0, 27.8, 27.3, 25.7
Sample mean(m) = 26
Sample standard deviation (s) = 1.624
t0 = (26 - 25) / (1.624 /√10) = 1.947
1.947 > 1.833
Hence, reject Null
B)
Confidence interval at 90% ; α = 0.1
m ± t(0.1/2 ; 9) * s/√n
m - t * s/√n ≤ μ ≤ m + t * s/√n
26 - 1.833 * (1.624/√10) ≤ μ ≤ 26 + 1.833 * (1.624/√10)
25.059 ≤ μ ≤ 26.941

Which graph shows the points (–3, 5) and (4, –3) plotted correctly?
Answer:
Step-by-step explanation:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.
Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.
Using this formula, we find three particular points on the graph:
(1, $2), (2, $4), (3, ($6)

D

Each of the 25 students in Mr. McDonald class sold 16 raffle tickets if each ticket cost $15 how much money did Mr. McDonald’s students raise PLEASE HELP
Answer:
Mr. McDonald's class raised $6,000 dollars.
Step-by-step explanation:
So they're are 25 students in the class and they each sold 16 raffle tickets. The easiest way to do this problem is to first find the amount of raffle tickets sold and then multiply that by 15. You could also just do 25*16*15 but that doesn't make much sense just thinking about it. So the first operation we have to do is 25*16 because multiplication is repeated addition so we're basically doing 16+16 25 times to see how much raffle tickets were sold. So that is 400 and then we multiply by 15 because each ticket sold for 15 dollars so if we sold 400 raffle tickets for 15 dollars each, again multiplication is repeated addition so we do 15+15 400 times which is 400*15=6,000. So Mr.McDonald's class raised $6,000 dollars.

use the functions to find f(-1/3)
Answer:
f(x) = 17/2 or 8.5
Step-by-step explanation:
f ( x ) = 10-9/2x
By substituting the values,
f (x) = 10 - 9/2(-1/3)
= 10-3/2 = 17/2= 8.5

Find X and Y in the figure
Answer:
x = 15
y = 19
Step-by-step explanation:
(5x-5) = (4x+10) reason[ being corresponding angle]
or, 5x-4x = 10+5
or, x = 15.
Similarly,
(5x-5)+(6y-4) = 180 reason[being supplementary angle]
putting the value of x in the equation, so
or, (5*15 -5)+(6y-4) = 180
or, 75-5+6y-4 = 180
or, 66+6y = 180
or, y = 30-11
or, y = 19.
