Autumn invested 2800 in a account paying an interest rate of 6.2% compounded monthly.Assuming no deposits or withdrawals are made how much money to the nearest ten dollars would be in the account after 8years
Answer:
4530.55
Step-by-step explanation:
2800 x 6.2% = 173.6
2800 + 173.6 = 3157.96
repeat this step 8 times because you need to find the money in the account after 8 years. Tell me if you need further explanation
at a school there are 10 students taking only chemistry, 9 students taking only physics 5 students taking both, and 16 students not taking either. if a student is randomly selected from the other school, what is the probability that they are taking chemistry or physics?
Answer:
If there are 10 students taking only chemistry, 9 students taking only physics, and 5 students only taking both chemisty and 16 students are taking neither; I would add 10+9+5+16=40 (total students) and divide 10/40 (25% chemistry) 9/40 (22.5% physics) 5/40 (12.5% both) 16/40 (40% neither)
Step-by-step explanation:
1. Determine a single event with a single outcome.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 72.6 Mbps. The complete list of 50 data speeds has a mean of x=18.55 Mbps and a standard deviation of s=19.69 Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
Answer:
a. 54.05 Mpbs.
b. 2.745... standard deviations.
c. The z-score is 2.745....
d. The carrier's highest data speed is significantly high.
Step-by-step explanation:
a. The difference between the highest measured data speed and the mean is 72.6 - 18.55 = 54.05 Mbps.
b. The amount of standard deviations of 54.05 Mbps is equal to this value divided by the standard deviations, so we yield [tex]\frac{54.05}{19.69} = 2.745...[/tex] standard deviations.
c. The z-score is equal to the difference between the mean and a data point in standard deviations, so the z-score is 2.745....
d. 2.745... is not between -2 and 2, so the carrier's highest data speed is not insignificant - so it's significantly high.

Show that the triangles are similar by comparing the ratios of the corresponding sides. Simplify your answer completely in order to be able to compare the ratios of the corresponding sides. Please help
Answer/Step-by-step explanation:
AC = 1.2
AB = 4
BC = 2.6
DF = 3
DE = 10
EF = 6.5
Thus:
[tex] \frac{DE}{AB} = \frac{10}{4} = \frac{5}{2} [/tex]
[tex] \frac{DF}{AC} = \frac{3}{1.2} = \frac{3*10}{1.2*10} = \frac{30}{12} = \frac{5}{2} [/tex]
[tex] \frac{EF}{BC} = \frac{6.5}{2.6} = \frac{6.5*10}{2.6*10} = \frac{65}{26} = \frac{5}{2} [/tex]
The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.

f - 3/4 = 1 1/2 please help !
Answer:
f = 2.25
Step-by-step explanation:
Given that,
[tex]f-\dfrac{3}{4}=1\dfrac{1}{2}\\\\f-\dfrac{3}{4}=\dfrac{3}{2}[/tex]
Adding 3/4 to both sides of the equation.
[tex]f-\dfrac{3}{4}+\dfrac{3}{4}=\dfrac{3}{2}+\dfrac{3}{4}\\\\f=\dfrac{6+3}{4}\\\\f=\dfrac{9}{4}\\\\f=2.25[/tex]
So, the value of f is equal to 2.25.

Answer:
Step-by-step explanation:
a). Stock price arranged as arithmetic sequence will be,
5, 8, 11, 14
b). Since, explicit formula of an arithmetic sequence is given by,
[tex]a_n=a+(n-1)d[/tex]
Here, [tex]T_n[/tex] = nth term of the sequence
a = first term
n = number of term
d = common difference
From the table attached,
First term of the sequence 'a' = 5
Common difference 'd' = 8 - 5 = 3
Therefore, explicit formula for the given sequence will be,
[tex]a_n=5+3(n-1)[/tex]
[tex]a_n=2+3n[/tex]
c). Slope intercept form of the equation will be,
y = 3x + 2
d). Input out values for the graph of the given equation,
x 0 1 2 3
y 2 5 8 11
By using this data we can graph the line.

Area of the triangle
=40 m²
height (h) = 8 m
Base (b) = ?
We know
Area of triangle = 1/2 * b * h
40 = 1/2 * b * 8
40 = 4b
b = 10 m

Amy bought some shirts and skirts for $168. Each shirt cost $17, and each skirt cost $22. She
bought a total of 9 items. How many shirts did Amy buy
Answer:
3 shirts and 6 skirts
Step-by-step explanation:
lets call number of shirts x and number of skirts y
so x+y=9
17x+22y=168
multiplying the first equation by 17 we get
17x+17y=153
17x+22y=168
subtracting we get
5x= 15
x=3
and we know x+y=9 so y=6
so 3 shirts and 6 skirts
if my answer helps please mark as brainliest.

John leaves to go home. He walks 6 blocks north and the 8 blocks west.how far is John from the school?
Answer:
The answer is 10 blocks.
Step-by-step explanation:
The answer is confusing but you would really ask your self what 5*2 would be because if you were to use blocks you would calculate the length of the route but not the direct distance of home to school.

Step-by-step explanation:
x ≤ 3 or x ≥ -1 represent the given graph.
Option (4) is correct.
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality.
As per the given diagram:
A line is drawn and a certain range of values are marked on the line,
To find the compound inequality that could be represented by the graph.
Because a number line with only real numbers is displayed in the provided graph.
We identify the solution set for each option by considering it separately.
1) -4 ≤ x ≤ 4
Since, the solution set contain only numbers between -4 and 4.
So it is false.
2) -2 ≤ x ≤ -1
This is a wrong representation.
3) x ≤ -1 or x ≥ 0
This represents all real numbers, excluding numbers between -1 and 0
So it is false.
4) x ≤ 3 or x ≥ -1
So it represents all the real numbers on number lines as shown in the graph below.
So, it is true.
x ≤ 3 or x ≥ -1 represent the given graph.
