Answer:
<em>(a) Denise received $640.</em>
<em>(b) The total amount the bank charged Denise was £11</em>
Step-by-step explanation:
<u>Proportions and Percentages</u>
The exchange rate between the American Dollar ($) and the British Pound(£) is $1.60= £1.
(a) Denise changed £400 into dollars. Applying the exchange rate:
£400 = 1.60*400 = $640
Denise received $640.
(b) To change the money, we need to add both fees the bank charged Denise:
A fixed amount of £3
2% of £400 = £8
The total amount the bank charged Denise was £11
The inequality to find the maximum number of t-shirts is:
Step-by-step explanation:
Debbie has at most $60 to spend
Then it will be <=60
Now she has to spend 22 dollars on jeans so 22 will be add to the initial amount for sure.
And
Let x be the number of t-shirts
Then the cost of x t-shirts will be 8x
Putting this in to inequality will be:
The inequality to find the maximum number of t-shirts is:

t = the number of years the money is invested for
Answer:
False
Step-by-step explanation:
given that a race car driver tested his car for time from 0 to 60 mph, and in 20 tests obtained an average of 4.85 seconds with a standard deviation of 1.47 seconds.
Sample size n = 20
since population standard deviation is not known, we can use t critical value for finding out the confidence interval
df=19
t critical = 2.045
Margin of error =
conidence interval = Mean±Margin of error
=
The given confidence interval is (4.52, 5.18)
Hence the statement is false.
