Answer:
Total money Betsy spent on T-shirt = £ 16.5
Total money Betsy spent on Bag = £ 28.5
Step-by-step explanation:
As given, Total money Betsy have = £ 75
Given that Betsy saved 40% of £ 75
⇒Betsy saved = £ 30
So, total money spent on T-shirt and bag = £ 75 - £ 30 = £ 45
Let Betsy spent money on T-shirt = x
Betsy spent money on Bag = y
⇒ x + y = £ 45 ........(1)
As given, She spent £12 more on the bag than she spent on the T-shirt.
⇒ y = £ 12 + x
Put the value of y in equation (1), we get
x + £ 12 + x = £ 45
⇒ 2x + £ 12= £ 45
⇒ 2x = £ 45 - £ 12
⇒ 2x = £ 33
⇒ x = £ = £ 16.5
⇒ x = £ 16.5
⇒ y = £ 12 + £ 16.5 = £ 28.5
∴ we get
Total money Betsy spent on T-shirt = x = £ 16.5
Total money Betsy spent on Bag = y = £ 28.5
Answer:
5. OPTION B.
6. OPTION J
Step-by-step explanation:
By definition:
- The Domain is the the set of all the input values. This is the set of all the x-coordinates (remember that the x-coordinate is the first number in each pair).
- The Range is the set of all output values, which is the set of all the y-coordinates ( Remember that the y-coordinate is the second number in each pair).
5. Observe the graph and write the coordinates of each point. These are:
Then, the relation shown in the graph is:
6. Based on the definition shown before, you can determine that the range of the relation shown in the graph is:
Answer:
The percent of the pairs that last longer than six months—that is, 180 days is 95.637%
Step-by-step explanation:
Mean = xbar = 208 days
Standard deviation = σ = 14
The standardized score for 180 days is the value minus the mean then divided by the standard deviation.
z = (x - xbar)/σ = (180 - 208)/14 = - 1.71
To determine the percent of boots that last longer than 180 days, we need this probability, P(x > 180) = P(z > (-1.71))
We'll use data from the normal probability table for these probabilities
P(x > 180) = P(z > (-1.71)) = 1 - P(z ≤ (-1.71)) = 1 - 0.04363 = 0.95637 = 95.637%
Well, $48.76 divided by 3 = 16.25333333333333
So, each student will get $16.25 with a penny left over.
