Answer:
x=1
Step-by-step explanation:
3(x+6)-5=16
3(x+6)=16+5
3(x+6)=21
x+6=21/3
x+6=7
x=7-6
x=1
3(x+6)-5=16
3(1+6)-5=16
3×7-5=16
21-5=16
16=16

Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to 1. response bias. 2. instrumentation bias. 3. researcher bias. 4. sampling bias.
Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.
The sale price of every item in a store is 85% of its usual price the usual price of backpack is $18 what is its sale price
Answer: the sale price is $2.70
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 18 × 85/100
Discount = 18 x 0.85
You save = $15.30
Final Price = Original Price - Discount
Final Price = 18 - 15.3
Final Price = $2.70

A high school teacher is interested to compare the average time for students to complete a standardized test for three different classes of students. The teacher collects random data for time to complete the standardized test (in minutes) for students in three different classes and the dataset is provided below. The teacher is interested to know if the average time to complete the standardized test is statistically the same for three classes of students. Use a significance level of 5%. The teacher has confirmed that the samples were randomly selected and independent, and the populations have normal distribution and the population variances are equal. (a) calculate the Test Statistic for this example (round your answer to 2 decimal places) (b) calculate the P-value for this example (round your answer to 2 decimal places)

If this figure is dilated by a scale factor of 3, what would the new coordinates be?
Answer:
J (-3,3), G (0,3), H (4,9), I (3,3)
Step-by-step explanation:
When your dilating a figuring it either gets larger or smaller. Since this is a positive number, and it is not a fraction then the figure is getting larger. Now you multiply each of the original coordinates by 3 to get the dilated coordinates.

Which equation and solution can be used to solve this problem?
Twenty-two less than a number is twenty-four.
q + 22 = 24: Subtract 22 from both sides. The answer is 2.
24 + q = 22: Subtract 22 from both sides. The answer is 2.
q minus 24 = 22: Add 24 to both sides. The answer is 46.
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Answer:
Step-by-step explanation:
22 less than a number, q-22, ‘is’ 24 is =24
q-22=24 adding 22 to both sides gives q=46
Answer:
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Step-by-step explanation:
Solve each equation to see if it works.
Q - 22 = 24 does work.

A car rental agency advertised renting. a car for $24.95 per day and $0.27 per mile. If Brad rents this car for 4 days, how many whole miles can he drive on a $200 budget?
Answer:
Around 370 when rounded
Step-by-step explanation:
ok so we know that for one day rental cost 24.95 and 0.27 per mile.
Brad has a budget of 200 and wants to rent a car for 4 days and wants to know how many miles he can drive with his budget.
First off you have to mulitply 24.95(which is how much the rental cost per day) by 4. 24.95 x 4=99.8 so out of his 200 dollars he now has 100 budget for miles.
Next we are going to divide the 100 dollars left out of the budget by the cost per mile which is 0.27. 100/0.27=370 when rounded.

Step-by-step explanation:
