Answer:
The answer is A got it correct on the test
Step-by-step explanation:
have a good day!
You'll need to use parentheses to indicate what is under the first radical sign and what is not. Did you mean radical(36a) or just radical 36?
I will assume that you meant radical(36a).
Then you have [radical(36a}*(b^4)*c^5.
This comes out to 6sqrt(a)*b^4*c^5.
I am almost positive the answer is B
Add 16+12 to get 28.
Add 9+12 to get 21.
Think of these as the sides of a triangle.
a^2+b^2=c^2
28^2+21^2=1225
√1225=35
You threw the ball 35 feet.
Answer:
Step-by-step explanation:
Hello!
To see if driving heavy equipment on wet soil compresses it causing harm to future crops, the penetrability of two types of soil were measured:
Sample 1: Compressed soil
X₁: penetrability of a plot with compressed soil.
n₁= 20 plots
X[bar]₁= 2.90
S₁= 0.14
Sample 2: Intermediate soil
X₂: penetrability of a plot with intermediate soil.
n₂= 20 (with outlier) n₂= 19 plots (without outlier)
X[bar]₂= 3.34 (with outlier) X[bar]₂= 2.29 (without outlier)
S₂= 0.32 (with outlier) S₂= 0.24 (without outlier)
Outlier: 4.26
Assuming all conditions are met and ignoring the outlier in the second sample, you have to construct a 99% CI for the difference between the average penetration in the compressed soil and the intermediate soil. To do so, you have to use a t-statistic for two independent samples:
Parámeter of interest: μ₁-μ₂
Interval:
[(X[bar]₁-X[bar]₂)±
*Sa
]


[(2.90-2.29)±2.715*0.20
]
[0.436; 0.784]
I hope this helps!
