Answer:
D) 0.5764.
Step-by-step explanation:
According to a standard z-score table, a z-score of -0.5 corresponds to the 0.3085-th percentile of a standard normal distribution.
Furthermore, a z-score of 1.2 corresponds to the 0.8849-th percentile of a standard normal distribution.
Therefore, the area under the standard Normal curve corresponding to -0.5 < Z < 1.2 is:
The answer is option D) 0.5764.
Question 19:
To get the answer we just have to round up the number then multiply...
9.8% = 10%
5.5% = 5%
19.8 = 20%
(Use the rounding rule, but in 2014 the 20 tons actually increase by 10%, this is where me multiply)
Our equation should look like 20(1.10) so far...
In 2015, we would need to increase the quantity by 5%, which means we would multiply that quantity by 1.05.
Answer:
D) 20(1.1)(1.05)
Question 27:
First, let's find out the discount during the sale, we know there was a 40% discount...
When we use percentages we know it's out of 100...so...
450 * (100% - 40%)
450 * (60%)
450 * (0.6
= 270
After the sale it increases by 40%...
100% + 40% = 140%
140% = 1.4
270 x 1.4
= 378
Answer:
C) 378
I hope this helps, hopefully my explanation made sense...
Tangent = Opposite÷ Adjacent
So the answer is D) 2

Answer:
V= 6912
Step-by-step explanation:
We are given in the diagram that the radius of the sphere is 12 cm. We are also asked to use the value 3 for pi. Simply insert these values for <em>r </em>and pi to complete the rest of the formula.
Remember, you are asked to use 3 as the value for pi, so make sure you included that in your work.
