Answer:
Alexandria requires 55 rows to use all the shells.
Step-by-step explanation:
Given:
Number of Shells = 329
Number of shells in each row = 6
We need to find the number of rows she need if she wants to use all the shells.
Solution:
Now we know that;
number of rows she needs can be calculated by Dividing Number of Shells with Number of shells in each row.
framing in equation form we get;
number of rows = 
Hence Alexandria requires 55 rows to use all the shells.
Answer:
y=−9x and y=−4
Step-by-step explanation:
68.2 % of the data is within one σ, either side of the mean
95.4 % of the data is within two σs, either side of the mean
99.7 % of the data is within three σs, either side of the mean
Therefore, 0.3 % of values lie outside the range of value of three σs.
We can say this is representative of the chance that a value (in this case, the lifetime of the fan) will exceed the mean value by more than three σs.
we have been given that in ΔFGH, the measure of ∠H=90°, GF = 53, HG = 28, and FH = 45. We are asked to find the ratio that represents the sine of ∠G.
First of all, we will draw a right triangle using our given information.
We know that sine relates opposite side of right triangle with hypotenuse.
We can see from the attachment that opposite side to angle G is FH and hypotenuse is GF.
Therefore, the ratio 
represents the sine of ∠G.
The ratio would be 3:5 when comparing Karen’s fish to Kay’s
