Answer:
SA = 18.2+10.4h
59.8yd²
Step-by-step explanation:
Surface area of a 3D shape is the sum of the areas of its faces. A rectangular prism is made of 2 rectangles that make the top and bottom, plus four equal, larger rectangles.
surface area = 2(small rectangles)+4(large rectangles)
surface area = 2(3.5*2.6)+4(2.6h)
SA = 18.2+10.4h
SA = 18.2+10.4h
SA = 18.2+10.4(4)
SA = 18.2+41.6
SA = 59.8yd²

Answer:
1.2803
Step-by-step explanation:
According to the Question,
- Given That, You want to invest in companies belonging to Gispa Group of 1 Companies, Inc. so you did some research and found out that companies belonging to this group have an average gain of 0.8 percent and a standard deviation of 0.7 percent.
- And, a positive percent (gain) means profit and a negative percent means a loss. If you choose 20 companies.
Therefore, We have Average Gain(ц) = 0.8%
Standard deviation(σ) = 0.7%
Number of Companies(n) = 20
- So, the probability that the companies are gaining more than 1 percent is
= (σ² × n) / ц ⇒ (0.7²×20) / (0.8*10) = 1.2803
Answer:
Kate's electric bill will be $9 for this month for bulb use only.
Step-by-step explanation:
Given:
Electricity bill lass month from bulb use = $12
Using new bulbs percent decrease in electricity = 25%
We need to find this month electric bill for bulb use.
Solution:
First we will find the reduction in bill after using new bulbs.
reduction in bill after using new bulbs can be calculated by percent decrease in electricity using new bulb multiplied by last month Electricity bill from bulb use only.
framing in equation form we get;
reduction in bill after using new bulbs =
Now we will find this month electric bill for bulb use only.
this month electric bill for bulb use only can be calculated by subtracting reduction in bill after using new bulbs from last month electric bill for bulb use only.
framing in equation form we get;
this month electric bill for bulb use only =
Hence Kate's electric bill will be $9 for this month for bulb use only.
