Answer:
The percentage of scores higher than 72 is 99.85%
Explanation:
The empirical rule states that about 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)
We can use the relationship below
255-σ(61)=72
61σ=255-72
61σ=183
σ=3
The area is as shaded below
The percentage of scores higher than 72 is 99.7%+0.15%=99.85%
Answer:
Tax multiplier = 3
Explanation:
Given:
Current MPC = 0.75
Find:
Tax multiplier
Computation:
Tax multiplier = MPC / [1 - MPC]
Tax multiplier = 0.75 / [1 - 0.75]
Tax multiplier = 0.75 / 0.25
Tax multiplier = 3

Answer:
T-Shirt Cost = £7
Hat Cost = £3
Explanation:
Important Information:
4 t-shirts and a hat costs £31.00
2 t-shirts and a hat costs £17.00.
Here we assume t-shirt be x and hat be y.
Explanation/Solution:
Based on the above information, the calculation is as follows:
4x + y = 31
2x + y = 17
Now subtract equation 2 from 1
2x = 14
x = 7
So y is
4(7) + y = 31
28 + y = 31
y = 3
Therefore we can conclude that The t-shirt cost £7 and Hat cost £3.
They both offer checking and savings accounts, mortgages, loans on homes and autos. These things are the things that they have in common.
