Answer:
If its a specific shape then probably the formula would be different.
If it were to be a parallelogram then multiply all given lengths
2 x 2 x 3 = 12cm
Answer:
x = -2/ 3
Step-by-step explanation:
in order to cancel out the logs they should have common bases
we can write 25 as 5²
we know that the reciprocal of the exponents of the bases are multiplied to the log
and now since the logs have common bases
we're left with
<u>x = -2/ 3</u>
The mean grade on the quiz was 88.
<u>Step-by-step explanation:</u>
We need to find the mean grade of the quiz using the information given.
The mean also known as the average is defined as the sum of data entries in a set divided by the number of entries in the data set.
The standard deviation gives the amount of variation or dispersion of data values present in a data set.
The given data are,
- The standard deviation of the quiz, SD = 3.
- The score 94 is exactly 2 standard deviations above the mean.
The above sentence represents that 94 is above the mean with 2 standard deviations.
⇒ 94 = Mean + 2 standard deviations.
We know the value for standard deviation. So substitute SD= 3 in the expression provided.
⇒ 94 = Mean + (2×3)
⇒ 94 = Mean + 6
To find mean, subtract 6 on both sides.
⇒ 94 -6 = Mean
⇒ Mean = 88
Therefore, the mean grade on the quiz was 88.
