The ratio on the lines state: gallons to cups is 4:64
This means for every 4 gallons, there are 64 cups. If you divide 64 by 4 you get 16.
Now you know for every 1 gallon, there are 16 cups.
Multiply 16 by 3 so you can figure out how many cups there will be for every 3 gallons.
The answer is 48 cups. For every 3 gallons, there will be 48 cups.
Answer:
The expected number of checks among 784 that should have a leading digit of "1" is 236.
Step-by-step explanation:
Let <em>X</em> = number of checks that has the leading digit as "1".
The probability of a check having a leading digit as "1" is, <em>p</em> = 0.301.
The number of checks issued by a suspected company is, <em>n</em> = 784.
A check is having a leading digit "1" is independent of other checks.
A randomly selected check either has the leading digit 1 or not.
The success of the experiment is defined as, a check having the digit "1" as the leading digit.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 784 and <em>p</em> = 0.301.
The expected value of a random variable is the average number of times the random variable occurs.
The formula to compute the expected value of a Binomial distribution is:
Compute the expected value of <em>X</em> as follows:
Thus, the expected number of checks among 784 that should have a leading digit of "1" is 236.
Answer:
No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Barbara buys 3 boxes of eggs costing £1.20 each
1 jar of mayo costing £1.80
2 loaves of bread
she pays £10 note and gets £1.60 change
Barbara works out the cost of 1 loaf of bread as £1.40.
Is she correct? You MUST show your working out.
The explanation of the answer is now given as follows:
Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60
Cost of 1 jar of mayo = £1.80
Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40
Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00
Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50
Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Answer:
YX and WX
Step-by-step explanation:
In an isoceles triangle, the sides WX and YX are equal which also means you can assume angle W and angle Y are also equal.
