We calculate the floor area of the kitchen:
A = (22) * (16)
A = 352 feet ^ 2
We consider the following conversion:
1 foot = 12 inches.
Applying the conversion we have:
A = 352 * (12/1) ^ 2
A = 50688 in ^ 2
We calculate the area of each tile:
A = (16) * (16)
A = 256 in ^ 2
Then, the number of tiles is given by:
N = (50688) / (256)
N = 198
Answer:
He needs to buy 198 tiles
Answer:
a) 3.128
b) Yes, it is an outerlier
Step-by-step explanation:
The standardized z-score for a particular sample can be determined via the following expression:
z_i = {x_i -\bar x}/{s}
Where;
\bar x = sample means
s = sample standard deviation
Given data:
the mean shipment thickness (\bar x) = 0.2731 mm
With the standardized deviation (s) = 0.000959 mm
The standardized z-score for a certain shipment with a diameter x_i= 0.2761 mm can be determined via the following previous expression
z_i = {x_i -\bar x}/{s}
z_i = {0.2761-0.2731}/{ 0.000959}
z_i = 3.128
b)
From the standardized z-score
If [z_i < 2]; it typically implies that the data is unusual
If [z_i > 2]; it means that the data value is an outerlier
However, since our z_i > 3 (I.e it is 3.128), we conclude that it is an outerlier.
Answer: 107
Step-by-step explanation:
1 Remove parentheses.
16x-80<2716x−80<27
2 Add 8080 to both sides.
16x<27+8016x<27+80
3 Simplify 27+8027+80 to 107107.
16x<10716x<107
4 Divide both sides by 1616.
x<\frac{107}{16}x<
16
107
Done
Each year it will gain $10 so it will take 50 years.
1,000 × .02 = 20
1,000 ÷ 20 = 50
1. Check the prices of phones from different stores.
2. Do some research to see what is the average cost of the phone.
3. Check for possible discounts.
Hope this helps :)
