{
if(1>=2)//defining if block to check value
{
cout<<"True";//print message
}
else//else block
{
cout<<"False"; //print message
}
return 0;
}

Explain why the exponent in 3.5 x 10 6 is 6 there are only 5 zeros in 3500000
Step-by-step explanation:
The given number is 3.5×10⁶. It is written in scientific form. We can first write it into standard form. There is exponent of 10 is 6.
3.5×10⁶ = 3.5×1000000
We can write 3.5 as 35/10
So,
3.5×10⁶ = (35/10)×1000000
= 3500000
One of the zero of 1000000 is divided by 10 at the denominator. Hence, the exponent in 3.5×10⁶ is 6 while there are 5 zeros in 3500000.

Step-by-step explanation:
2) f(x) = 27x^6+ 1524x^3+125
Answer:
Step-by-step explanation:
Let x^3 = y
f(x) = 27(x^3)^2 + 1524(x^3) + 125
f(x) = 27 y^2 + 1524y + 125
You can now put this into the quadratic formula. When you do, you get
(y + 0.0821)(y+56.3623) = 0
So now you substitute x^3 into this
(x^3 + 0.0821)(x^3 + 56.3623)
x^3 + 0.0821 = 0
x^3 = - 0.0821
cuberoot x^3 = cube root 0.0821
x = - 0.4346
x^3 = - 56.3623
x = - 3.8341

1. Calculate the federal income taxes. In 2018, the federal income tax was 10 percent on incomes between $0 and $9,525 per year, 12 percent on incomes between
$9,526 and $38,700, and 22 percent on Incomes between $38,701 and $82,500. In 2018, you made $42,000. What was your income tax this year?
O $5,040
$8,400
$4,200
$9,240
Answer:
$9,240.
Step-by-step explanation:
Given that in 2018, all salaries between $ 38,701 and $ 82,500 had to pay a federal income tax of 22%, and that my salary in that year was $ 42,000, to determine the amount that I had to pay in concept of said tax, the following calculation must be done:
(42,000 x 22) / 100 = X
924,000 / 100 = X
9,240 = X
Therefore, the amount of federal income tax that I had to pay in 2018 was $ 9,240.
1) The original price of the shorts is $35. They are on sale for 25% off. a) What is the discount amount? b) What is the sale price?
Answer:
26.25
Step-by-step explanation:
Answer:
A. $8.75 B. $26.25
Step-by-step explanation:
To figure this out, multiply .25 by 35 to find out what 25% of 35 is. The answer is $8.75, meaning that the shorts are $8.75 cheaper than the original price.
To find the on sale price, subtract $8.75 from $35. The answer is $26.25, meaning that the on sale price is $26.25.

The population of a particular type of bacteria is known to triple in 22 days. What is the daily growth rate
Answer: ∛(3)
Step-by-step explanation:
Suppose that at day 0 the population was A.
at day 3, the population will be: 3*A
at day 6, the population will be 3*(3*A) = A*3^2
then, at day N = 3*n (where n = 0, 1, 2.....) the population will be:
P(N) = A*3^n
Particularly, if we take n = 1/3 we will have:
N = 3*1/3 = 1
This means that this is the first day after the day 0.
P(1) = A*3^(1/3)
(then in day one, the population grow by a factor of 3^(1/3))
N = 2 is when n = 2/3, then:
P(2) = A*3^(2/3)
The quotient between P(2) and P(1) is equal to the growth between day one and day two, this should be the same as the growth between day zero and day one.
A*3^(2/3)/(A*3^(1/3)) = 3^( 2/3 - 1/3) = 3^(1/3)
So we found that the daily growth rate is 3^(1/3) or ∛(3)
The daily growth rate of the bacteria is an illustration of unit rates
The daily growth rate of the bacteria is 0.136
For 22 days, the population of the bacteria triples.
The daily rate is the amount of bacteria each day.
So, we have:
[tex]\mathbf{Daily = \frac{Rate}{Days}}[/tex]
This gives
[tex]\mathbf{Daily = \frac{3}{22}}[/tex]
Divide
[tex]\mathbf{Daily = 0.136}[/tex]
Hence, the daily growing rate of the bacteria is 0.136

Complete Question
The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims will be more depressed, so you formulate the null and alternative hypotheses as:
[tex]H_o: \ \ \mu_{victims} - \mu_{bully-victims} = 0H1: \ \ \mu _{victims} - \mu_{bully-victims} \ne 0[/tex]
You conduct an independent-measures t test. Given your null and alternative hypotheses,
this is a ________ [ Select ] ["two-tailed", "one-tailed"] test.
The degree of freedom is __________ [ Select ] ["46", "48", "24", "22"]
and for an alpha of .01, the critical t is +/- _________ [ Select ] ["2.704", "2.021", "1.684"]
In order to calculate the t statistic, you first need to calculate the standard error under the assumption that the null hypothesis is true. In order to calculate the standard error, you first need to calculate the pooled variance. The pooled variance is ________ [ Select ] ["72.8696", "145", "0.3756", "71.3201"] .
The standard error is ___________ [ Select ] ["2.4664", "2.5572", "1.9543", "72.8712"] .
The t-statistic is _________ [ Select ] ["1.95", "2.55", "-1.70", "-2.25"]
Answer:
First Question
The correct option is "two-tailed"
Second Question
The correct option is "46"
Third Question
The correct option is "2.704"
Fourth Question
The correct option is "72.8696"
Five Question
The correct option is "2.4664"
Sixth Question
The correct option is "1.95"
Step-by-step explanation:
From the question we are told that
The number of victims is [tex]n_1 = 25[/tex]
The sample mean is [tex]\= x_1 = 25.3[/tex]
The standard deviation is [tex]s_1 = 9[/tex]
The number of bully victims is [tex]n_2 = 23[/tex]
The sample mean is [tex]\= x_2 = 20.5[/tex]
The standard deviation is [tex]s_2 = 8[/tex]
Generally this is a two -tailed test because from the null and the alternative hypothesis we see that the test is know whether the mean number of victims is significantly more depressed than bully -victims or significantly less depressed than bully -victims
Generally the degree of freedom is mathematically represented as
[tex]df = n_1 + n_2 -2[/tex]
=> [tex]df = 25 + 23 -2[/tex]
=> [tex]df = 46[/tex]
Generally from t distribution table the critical value of [tex]\alpha = 0.01[/tex] for a two-tailed test at a degree of freedom of [tex]df = 46[/tex] is
[tex]t_{0.01 , 46} = \pm 2.704[/tex]
Generally the pooled variance is mathematically represented as
[tex]s^2 = \frac{(n_1 - 1) s_1^2 + (n_2 - 1)s_2^2}{df}[/tex]
=> [tex]s^2 = \frac{(25 - 1) 9^2 + (23 - 1)8^2}{46}[/tex]
=> [tex]s^2 = 72.8696[/tex]
Generally the standard error is mathematically represented as
[tex]SE = s \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]
[tex]SE = \sqrt{s^2} * \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]
=> [tex]SE = \sqrt{72.8696} * \sqrt{\frac{1}{25} + \frac{1}{23} }[/tex]
=> [tex]SE = 2.4664[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x_ 1 - \= x_2}{SE }[/tex]
=> [tex]t = \frac{25.3 - 20.5}{ 2.4664 }[/tex]
=> [tex]t =1.95[/tex]
To test if bully-victims are more depressed, we have that:
The null hypothesis is [tex]H_0: \mu_B - \mu_{NB} = 0[/tex]The alternative hypothesis is: [tex]\mu_M - \mu_{NB} < 0[/tex]For our test, we consider that:
The mean score of bully victims is given by: [tex]\mu_B[/tex].The mean score of non-bully victims is given by: [tex]\mu_{NB}[/tex]At the null hypothesis, we test that they have the same scores, that is:
[tex]H_0: \mu_B = \mu_{NB}[/tex]
Which can also be written as:
[tex]H_0: \mu_B - \mu_{NB} = 0[/tex]
At the alternative hypothesis, we test if the score of bully victims is less than the score of non-bully victims, that is:
[tex]H_1: \mu_B < \mu_{NB}[/tex]
[tex]H_1: \mu_B - \mu_{NB} < 0[/tex]
