Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)
75 coz if u divide 36/48 x100/1 it will give you 6/8x100/1 and u will divide 6/8 by 2 it will give you 3/4x100/1 that hundred u will divide it by 4 and it will give u 25 then it will remain 3 and 25 then u will multiply 3x25 and the answer will be =75%..thanks
Answer:
He earns $51.02
Step-by-step explanation:
If Michael earns an 8% commission, then he is paid 8% of what he sells it for. Therefore, he earns 8% of $637.75.
Your equation is y = 0.08 × 637.75
y = 51.02
He earns $51.02
The volume outside the pyramid but inside the prism is 250 cubic centimeters.
Step-by-step explanation:
Step 1:
First, we determine the volumes of the rectangular prism and the pyramid.
The volume of a rectangular prism is calculated by multiplying its length, its width, and its height.
The length and width are both 5 cm while the height is 12 cm.
The volume of the rectangular prism .
The volume of the prism is 300 cubic centimeters.
Step 2:
The volume of a square pyramid is given by , where a is side length and h is the height of the pyramid.
The height of the pyramid is half of the prism, so cm and cm.
The volume of the pyramid
The volume of the pyramid is 50 cubic centimeters.
Step 3:
The volume outside the pyramid but inside the prism
The volume is 250 cubic centimeters.
Answer:
Step-by-step explanation:
Both 115 and 145 mph are above the mean. Draw a normal curve and mark these speeds. 115 mph is 1 standard deviation above the mean; 130 would be 2 standard deviations above the mean; and 145 would be 3 s. d. above it.
We need to find the area under the standard normal curve between 115 and 145. This is equivalent to the area under the standard normal curve between z = 1 and z = 3.
I used my TI-83 Plus calculator's DISTR function "normalcdf(" to calculate this area: normalcdf(1, 3) = 0.1573.
The area between z = 1 and z = 3 is 0.1573. In other words, the percentage of serves that were between 115 and 145 mph was 15.73%.
