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

The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,
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,

Charlie says the difference between the least amount of time it takes a student to complete the math problem and the greatest amount of time is minutes. Is he correct? Explain.
Answer:
1 is correct
Step-by-step explanation:
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.

Answer:
you were right
Step-by-step explanation:
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 :)

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.
Find the area. Do not include the units
Answer:
19.95cm²
Step-by-step explanation:
Okay, so I don't know what "do not include the units means", so I'm sorry if this is wrong, but the formula for the area of a parallelogram is height x width. Lucky for us, we have both so we just have to plug:
3.4 x 5.7 = 19.95
So, the area of the parallelogram is 19.95cm²

sharon bought a $2,100 high definition television set on a six month rent to own plan. the down payment was 10%. what was the dollar value of the down payment? her monthly payments were $75 per month. if she decides not to buy the HDTV after the six months, what was her cost to rent it?
Answer:
Total Sharon spent $660 for the tv
The down payment was $210
The amount that she paid for rent after 6 months is $450
Step-by-step explanation:
To find out how much her down payment was you would need to find out how much 10% of $2,100 is which is $210, so you know her down payment was $210.
Then you would find out the total cost of rent is after 6 months so you would do 6 times $75 which is $450. So if she decides to not buy it then after 6 months she would have spent $450 to rent it.
And total she would have spent $660 which you can find out by doing $450 + $210 = $660.
