One has $1000 in his bank account to use for education after high school he spends 3% of this amount every month how much money does he have in his account every month
Answer:
Every month, he will spend $30 of his $1000.
Step-by-step explanation:
The first thing I did was found out 3% of 1000. To do this, you need to move the decimal point in 3% over twice. Like this:
3 → .03
Then, multiply 1000 by .03.
1000 * .03 = 30
So, this means that he will spend $30 of his money each month.

Write an expression to describe the sequence below. Use n to represent the position of a
term in the sequence, where n = 1 for the first term.
11, 12, 13, 14, ...
Answer:
n+10
Step-by-step explanation:
This is applicable because if you plug in the numbers it will work for example. -
what sequence is 12 in, it is the second number so n=2
so add 10 to 2 which is 12
So as seen the answer is n+10

The function f(3) = 50.000(0.975)", where x represents the underwater
depth in meters, models the intensity of light below the water's surface in lumens per
square meter. What is the intensity of light 200 meters below the surface
9514 1404 393
Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Answer:
using Thales theorem, we have:

Answer:
x=35 y=18
Step-by-step explanation:
We have two triangles. These triangles are Similar as stated in the statement. Since they are similar, there side length will be in proportion.
To find x and y we need to set up a proportion of the corresponding sides of the triangles.
Let find the corresponding sides of both triangle.
JK corresponds with NM
KL corresponds with ML
JL corresponds with NL
To find side x we can use this proportion
JK/KL=NM/ML
Plug in the lengths
[tex] \frac{40}{kl} = \frac{16}{14} [/tex]
Cross multiply
[tex]560 = 16kl[/tex]
Divide by 16
[tex]kl = 35[/tex]
so x=35
Now to find y use this proportion
JL/JK=LN/NM
[tex] \frac{45}{40} = \frac{y}{16} [/tex]
Cross multiply
[tex]720 = 40y[/tex]
[tex]y = 18[/tex]
Answer:
X = 35
Y = 18
Step-by-step explanation:
The triangles are similar meaning that they are scaled up and down differently. ( and in this case rotated) Notice the shape of the triangles. The side measuring 40 in the larger triangle correlates to the side measuring 16 in the smaller triangle. We can use this to find the scale difference between the two triangles. 40/16 = 2.5. The larger triangle is scaled up 2.5 times the smaller triangle. X correlates to the side measuring 14. Scale 14 up 2.5 times. 14* 2.5 = 35, so x= 35.
Y correlates to the side measuring 45. Scale 45 down 2.5 times. 45/2.5 = 18. Y = 18

100 poi's SOLVE FAST PLZ AND I WILL GIVE BRAINLEITS I PORMISE
Answer:
8,10,12
Step-by-step explanation:
Answer:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12
Step-by-step explanation:
integer 1 = x , smallest
integer 2 = y , x+12
integer 3 = z , largest, x+4
three times the smallest is twice the largest.
3 (x) = 2 (x+4)
solve for x:
3x = 2x + 8
3x-2x = 8
x = 8
Replacing:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12

Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. This figure had increased 6% over the previous two years. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago. Assume a population standard deviation of 1,550 customers. Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391. You wish to test the claim stated above at the 0.10 level. Run the appropriate hypothesis test.
Required:
Write ONLY the conclusion to your hypothesis test.
Answer:
Accept the null hypothesis
Step-by-step explanation:
Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago.
The null hypothesis is:
[tex]H_{0} = 3173[/tex]
The alternate hypothesis is:
[tex]H_{A} \neq 3173[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Due to our test, we have that [tex]\mu = 3173[/tex]
Assume a population standard deviation of 1,550 customers.
This means that [tex]\sigma = 1550[/tex]
Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391.
This means that [tex]n = 73, X = 3391[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3391 - 3173}{\frac{1550}{\sqrt{73}}}[/tex]
[tex]z = 1.24[/tex]
p-value:
Since we are testing if the mean is different of a value, and the z-score is positive, the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 1.24.
z = 1.24 has a pvalue of 0.9251
2*(1 - 0.9251) = 2*0.0749 = 0.1498
0.1498 > 0.1, which means that we accept the null hypothesis, that is, that the mean weekly number of customers is equal to what it was two years ago at the 0.1 level of significance.

Answer:
9x²+12=0
Step-by-step explanation:
Find the equation of the line with slope m=−12 that contains the point (2,−4).
Answer:
y=-12x+20
Step-by-step explanation:
-4=-12(2) +b
-4=24+b
(add 24 both sides)
20=b
slope: -12
y intercept: (0,20)
Answer:
y + 4 = -12(x - 2)
Step-by-step explanation:
Use the point-slope formula for the equation of a straight line:
y - k = m(x - h)
Here m = -12, h = 2 and k = -4, and so we have:
y + 4 = -12(x - 2)
