You can use addition to solve this problem. 7+_= 15
Answer:
Step-by-step explanation:
Calculate price per unit:
7/5.10= $1.37
So the answer is the store selling 10 tomatoes for $6.30 is the lower unit price
The tomoatoes if they were sold at Sally’s instead would cost $4.41
The answer is 42 why, because 42 divided by 6 equals 7 plus 14 is 21 and then you double it so it's 42.
Answer:
Step-by-step explanation:
1)
Percentile is related to the area under the standard normal curve to the LEFT of a certain data value (which in this case would be 26.1 inches).
On my Texas Instruments TI-83 Plus calculator, I found this area as follows:
normcdf(-100, 26.1, 28.4,1.2), where the range -100 to 26.1 represents the area (as a decimal fraction) to the left of 26.1 inches. My result was 0.028, which corresponds to the 3rd percentile (0.028 rounds off to 0.03, which would be 3rd percentile).
2) The mean waist size is 28.4 inches, represented by a vertical line through the standard normal curve lying between 24 and 32. We use the same function on the calculator: normcdf(24, 32, 28.4, 1.2).
The result is 0.9985. Subtracting this from 1.0000, we get 0.001, or 0.1%, which is the percentage of female soldiers requiring custom uniforms.
For the question above we can use the law of sine that states;
a/sinA = b/sinB = c/sinC
Where a is the opposite side of angle A
b is the opposite side of angle B
c is the opposite side of angle C
x/sin63 = 65/sin40
x = 65(sin63)/sin40
= 57.9154/0.6429
= 90.10
The answer is <span>A) 90.1 by The Law of Sines (SAS)</span>
