Answer:
24, 40
Step-by-step explanation:
The area of a triangle is given by the formula
where
b is the length of the base
h is the length of the height
For the 1st triangle here, we have:
b = 6 is the base
h = 8 is the height
So, the area of the triangle is
For the 2nd triangle here, we have:
b = 8 is the base
h = 10 is the height
So, the area of the triangle is
Answer: 0.4667
Step-by-step explanation:
According to 68–95–99.7 rule , About 99.7% of all data values lies with in 3 standard deviations from population mean ().
Here , margin of error = 3s , where s is standard deviation.
As per given , we have want our sample mean to estimate μ μ with an error of no more than 1.4 point in either direction.
If 99.7% of all samples give an within 1.4 , it means that
Divide boths ides by 3 , we get
Hence, So must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an
within 1.4 point of μ .
Answer:
$4.
Step-by-step explanation:
Let us assume that Pete and Teegan each put an amount of $P in a new bank account.
Teegan's account earns 2.75% simple interest and she earned $2.20 in interest after one year.
So, we can write
⇒ P = $80
Now, this $80 in Pete's account earns 5% simple interest.
Then after one year Pete will earn as interest Dollars. (Answer)
