What is the approximate value of q in the equation below? q log Subscript 2 Baseline 6 = 2 q 2 â€""1. 613 â€""1. 522 0. 585 3. 79.
The approximate value of q in the equation is [tex]0.774[/tex]
The equation is given as:
[tex]q\log_2(6) = 2[/tex]
Divide both sides of the equation by [tex]\log_2(6)[/tex].
So, we have:
[tex]q= \frac{2}{\log_2(6) }[/tex]
Determine log(6) base 2
[tex]q= \frac{2}{2.585}[/tex]
Divide 2 by 2.585
[tex]q= 0.774[/tex]
Hence, the approximate value of q in the equation is [tex]0.774[/tex]

Answer:
x = 7
Stepbystep explanation:
3 + x = 10

x = 7
you subtract by 3 on both sides (because the opposite property of addition is subtraction) to cancel it out and isolate the x.

Hi can someone pls help me with this!!!
the domain is the x value (first number) and the range is the y value (second number)
(if a number appears more than once in the domain or range, like in number 1 you don't have to write it again.)
to graph the domain and range you just plot the points,
and to map them you have to put the x values in the first oval and the y values in the second, usually in order from smallest to largest.
then you have to draw arrows connecting each x value to the y value that was in the same pair. just like when writing down the domain/range, if a number comes up again you don't have to write it down again. instead, you might have two or more arrows connecting to the same number.

Select the correct answer. Evaluate the following expression when x = 4 and y = 4. A. B. C. D.
The value of given expression when x=4 and y=4 is 1250.
The expression is missing in the question which is [tex]\dfrac{x^6x}{4y}[/tex].
We have to solve it for x= 4 and y = 4.
Now putting the value of x and y we get,
[tex]\dfrac{x^6x}{4y}=\dfrac{(4)^6(4)}{4}[/tex]
[tex]\dfrac{x^6x}{4y}=\dfrac{4096+4}{4}[/tex]
[tex]\dfrac{x^6x}{4y}=1250[/tex]
Hence the value of given expression when x=4 and y=4 is 1250.

2. A small university is trying to monitor its electricity usage. For a random sample of
30 weekend days (Saturdays and Sundays), the student center used an average of 94.26 kilowatt hours (kWh) with standard deviation 43.29. For a random sample of 60 weekdays, (Monday  Friday), the student center used an average of 112.63 kWh with standard deviation 32.07.(Please show work)
a) Test, at the 5% level, if significantly more electricity is used at the student center, on average, on weekdays than weekend days. Remember to check the conditions, identify the hypotheses, define your parameter, find the test statistic, find the pvalue, and give a conclusion in context.
b) Construct a 95% confidence interval for the difference in mean electricity use at the student center between weekdays and weekend days. Use two decimal places in your margin of error.
Using the tdistribution, it is found that:
a) Since the test statistic is greater than the critical value for the righttailed test, it is found that there is enough evidence to conclude that significantly more electricity is used at the student center, on average, on weekdays than weekend days.
b) The 95% confidence interval for the difference in mean electricity use at the student center between weekdays and weekend days is (3.56, 33.18).
Item a:
At the null hypothesis, it is tested if there is no difference, that is, the subtraction is at most 0, hence:
[tex]H_0: \mu_1  \mu_2 \leq 0[/tex]
At the alternative hypothesis, it is tested if there is difference, that is, the subtraction is positive, hence:
[tex]H_1: \mu_1  \mu_2 > 0[/tex]
The standard errors are given by:
[tex]s_1 = \frac{32.07}{\sqrt{60}} = 4.14[/tex]
[tex]s_2 = \frac{43.29}{\sqrt{30}} = 7.9[/tex]
The distribution of the difference has mean and standard deviation given by:
[tex]\overline{x} = \mu_1  \mu_2 = 112.63  94.26 = 18.37[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{4.14^2 + 7.9^2} = 8.92[/tex]
The standard deviation are given for the samples, hence, the tdistribution is used.
The test statistic is given by:
[tex]t = \frac{\overline{x}  \mu}{s}[/tex]
In which [tex]\mu = 0[/tex] is the value tested at the hypothesis.
Hence:
[tex]t = \frac{\overline{x}  \mu}{s}[/tex]
[tex]t = \frac{18.37  0}{8.92}[/tex]
[tex]t = 2.06[/tex]
The critical value for a righttailed test, as we are testing if the mean is greater than a value, with a significance level of 0.05 and 30 + 60  2 = 88 df is [tex]t^{\ast} = 1.66[/tex]
Since the test statistic is greater than the critical value for the righttailed test, it is found that there is enough evidence to conclude that significantly more electricity is used at the student center, on average, on weekdays than weekend days.
Item b:
The interval is:
[tex]\overline{x} \pm t^{\ast}s[/tex]
Hence:
[tex]\overline{x}  t^{\ast}s = 18.37  1.66(8.92) = 3.56[/tex]
[tex]\overline{x} + t^{\ast}s = 18.37 + 1.66(8.92) = 33.18[/tex]
The 95% confidence interval for the difference in mean electricity use at the student center between weekdays and weekend days is (3.56, 33.18).

how do you compute the area of the triangle
which mapping diagram does NOT represent a function from x > y ?
Answer:
A
Stepbystep explanation:
In a function, each x value must have a singular y value. This means that one xvalue (the values on the left) may not have a line pointing to 2 different yvalues (the values on the right). In the first relation, the xvalue of 6 points to both 4 and 6. This means that the value repeats, and in a function xvalues cannot repeat.
However, yvalues can repeat. So, situations like that seen in D, where both the xvalues of 2 and 4 equal the yvalue of 6 are fine.

3. Allison bought some shirts for her clothing store for $15 each. She received $50 off her entire purchase and spent a total of $400. How many shirts did Allison purchase for her store?
Answer:
30
Stepbystep explanation:
15x30 = 450
Answer:
She purchased 30 shirts.
Stepbystep explanation:
She paid only $400 Dollars, because she got a discount of $50.
So the total before getting the discount was $450.
If you divide $450 by $15 (the price for 1 shirt) you come up with 30.
450/15 = 30
