A study was designed to investigate the effects of two variables (1) a student's level of mathematical anxiety and (2) teaching method on a student's achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method. These students obtained a mean score of with a standard deviation of on a standardized test. Assuming a mound-shaped and symmetric distribution, in what range would approximately % of the students score?
Answer:
Solution using the Empirical Rule, which is explained here.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
The question is incomplete, but you solve this using the Empirical Rule.

Answer:
1. When combining 5+2+3 it equals 10; and when solving 5+(2+3) you solve what's in the parenthesis first. So the new problem is 5+(5), which equals 10.
2. Same goes for the second one, 11-2 is 9, then you just add the a because both have the same variable
hope that helped :) have an amazing day
Answer:
for 1: yes they are the same
for 2: true
Step-by-step explanation:
for 1: 5+2+3=10 and 5 +(2+3) = 10 because 2+3=5 so 5+5=10 therefore they are the same
For:2 9=11-2 because 11-2=9

Which ratio is smaller? 1:2 or 2/5
Answer:
2/5
Step-by-step explanation:
Answer:
2/5
Step-by-step explanation:
The easiest way to do this (in my opinion) is to make both of them into a fraction, then decimal, and then compare the two.
1:2=1/2=0.5
2/5=0.4
And once you do that you can see that 2/5(0.4) is smaller!
I hope this helps, and have a great day! :) <3
If you multiply me by 7, add 2 and divide by 3. You get 10. What number am I?
Answer:
4
Step-by-step explanation:
4 times 7 = 28
28 + 2 = 30
30/3 = 10
Answer:
4
Step-by-step explanation:
In numerical terms, write down what the problem says to,
( 7x + 2 ) ÷ 3 = 10
Now solve with inverse operations and simplification,
( 7x + 2 ) ÷ 3 = 10
*3 *3
7x + 2 = 30
-2 -2
7x = 28
÷7 ÷7
x = 4
Make an algebraic expression to determine the 15th term of this pattern:
63, (63+23), (63+23+30), (63+23+30+37), ...
And please, give me a complete answer with a step-by-step explanation.
Answer:
63+23+30+37+44+51+58+65+72+79+86+93+100+107+114.
Step-by-step explanation:
1. according to the condition 63+23; 63+23+30; 63+23+30+37+...; is an arithmetic sequence (note, 63 does not belong to it);
2. according to the condition the 1st term is 63+23; the 2d term is 63+23+30; the 3d term is 63+23+30+37, etc. It means, the next term is calculated with '+7';
3. according to the item '1.' the number '63' was excluded from the initial pattern. It means, the 14th term should be calculated: 23+7*(14-1)=114.
4. if number '63' is included into the given pattern again, the 15th term of the given pattern is 63+0+23+30+...+98.
5. the 15th term is:
63+23+30+37+44+51+58+65+72+79+86+93+100+107+114.
