Answer:
2.5 yearsStep-by-step explanation:
Given
Investment P = $16800Interest rate r = 5% = 0.05 Final amount A = $18900Time t = ?Use the formula
A = P(1 + rt), where A - final amount, P - investment, r- interest rate, t- timeSubstitute the given numbers and solve for t:
18900 = 16800( 1 + 0.05t)1 + 0.05t = 18900/168001 + 0.05t = 1.1250,05t = 0.125t = 0.125/0.05t = 2.5 years

Find the total surface area of these rectangular boxes when they are (i) lidless and (ii) hollow.
a. length = 15cm, breadth = 10cm, height = 6cm
Answer: 450 cm squared if not including the inside surface
900 cm squared if including the inside suface
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
but we have a lidless box so we need to subtract the lid...
600-(wl)=
600-(150)=450
If we are including the inside surface it would double as we would be covering both exposed surfaces of bottom, 2 ends, and 2 sides....
450x2=900
The surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
(i) The surface area will be calculated as,
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
But we have a lidless box so we need to subtract the lid.
600-(wl)=
600-(150)=450
(ii) If we are including the inside surface it would double as we would be covering both exposed surfaces of the bottom, 2 ends, and 2 sides.
450x2=900
Therefore, the surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.

2^2x-4^(2^x)+3=0 find the positive value of x
Answer:
0 and 1.5850
Step-by-step explanation:
Given the expression
2^2x-4^(2^x)+3=0
Let P = 2^x
P² - 4P + 3 = 0
Factorize
P² -3P-P +3 = 0
P(P-3)-1(P-3) = 0
P-1 = 0 and P-3 = 0
P = 1 and 3
If P = 1
2^x = 1
log 2^x = log 1
xlog 2 =0
x = 0/log 2
x = 0
Also if P = 3
2^x = 3
x log 2 = log 3
x = log3/log 2
x = 0.4771/0.3010
x = 1.5850
Hence the positive value of x are 0 and 1.5850

Find five numbers so that the mean, median, mode and range are all 4.
Answer:
The set of five numbers would be {2,4,4,4,6}
Answer:
The example set could be:
S
=
{
2
,
4
,
4
,
4
,
6
}
See explanation.
Explanation:
First you can notice that if the set was:
S
1
=
{
4
,
4
,
4
,
4
,
4
}
then it would fulfill 2 conditions: mean and median, but
the set does not have the mode because all numbers are the same,
the range is zero (again all numbers are the same)
To have the mode the set would have to have at least one element different from
4
, but if we changed only one element the mean would change, so at least two numbers need to be changed to keep mean equal to
4
..
Now to get the range the difference between the changed numbers should be
4
. That leads us to adding two to one number and subtracting two from the other.
Finally we can get the set from the answer.

180-104 is 76 76-10=66 66/2 is 33
Answer: x = 33
Step-by-step explanation:
Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)

The question on the top is
A student spins The spinner once and rolls the 1-6 number cube once. The second question is
What is the probability a student spends an even number and rolls an odd number, written as a percentage?
10 points this is due tomorrow.
Answer:
Option C
Step-by-step explanation:
For the spinner,
Probability of spinning an even number = [tex]\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
Favorable outcomes = even numbers on the spinner
= 3
Total outcomes = Total numbers on the spinner
= 6
Probability of spinning an even number = [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex]
For the cube,
Total outcomes = total numbers on the dice = 6
Favorable outcome = Odd numbers on the dice = 3
Probability of rolling an odd number on rolling a cube = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Probability of spinning an even number on spinner and an odd number on a cube = [tex]\frac{1}{2}\times \frac{1}{2}[/tex]
= [tex]\frac{1}{4}[/tex]
Percentage probability = [tex]\frac{1}{4}\times 100[/tex]
= 25%
Option C is the answer.

the sample size is:
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. The sample size is 19.
What is independent t-test?The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.
T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.
We perform one sample z-test;
One sample z-test is performed if the sample size is large enough (n > 30) and we want to know if the sample comes from the specific population.
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,
The sample size is 19.

An employee gets a signing bonus of $100 and is paid $25 per hour they work. Represent this scenario by writing an equation for x hours worked
Answer:
$(100 + 25x )
Step-by-step explanation:
X= number of hours
The numbers are just like money just without the dollar sign
100 + 25(x)
After you get your number remember to put your sign you were looking for
Hope I helped you out:)
Answer:
$(100 + 25x)
Explanation:
if the employee works for 1 hour, they earn 1 × $25 = $25. if they work for 2 hours, they earn 2 × $25 = $50. thus, representing the number of hours they work by x, we can say that they earn $(25x) per hour.
now, we add on the signing bonus: $(100 + 25x).
