Answer:
352 m^2
Step-by-step explanation:
Each of the four congruent triangular faces has an area that is half the product of the base edge length and the slant height:
A = 1/2·bh = 1/2·(8 m)(22 m) = 88 m^2
Then the total lateral area is 4 times this:
LA = 4·88 m^2 = 352 m^2
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀
Number of architecture majors = 100
We need to check that whether students at her university had an internship rate that was higher than the national average.
Proportion for her university = 43% = p₁
Here, n = 100
Since n > 30.
so, we can use z-test.
Z-test is generally use to identify whether two means are different when the standard deviation is given.
Hence, it is safe to use the z-test for p.
Therefore, option 'a' is correct.
Answer:
x^2 + 5x
Step-by-step explanation:
It is saying you multiply x times (x+5) so you distribute the x to both of the numbers in the parenthesis ending up with x^2 + 5x
Answer:
43,000: 4.3×10^4
0.0072: 7.2×10^-3
0.0000901: 9.01×10^-5
Step-by-step explanation:
scientific notation: a×10^b, where should be 0<a<10
Step 1. Count the zeros
Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit
------------------------
43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)
0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)
0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)
Hope this helps!! :)
