Answer:
YES
Step-by-step explanation:
==>Given:
=>Area to be painted = area of 1 long wall + area of 1 short wall = (3.49m*2.65m) + (2.98m*2.65m)
= 10.441 + 7.897
Area to be painted ≈ 18.34 m²
Cost of painting:
2.5L of paints costs £16 and covers 30m²
Therefore, litres of paint to cover 18.34 m² = (2.5L*18.34)/30 = 45.85/30 ≈ 1.5L
2.5L costs £16
Therefore, 1.5L costs = (16*1.5)/2.5 = 24/2.5 = £9.6
==>Area to be covered with wall paper = area of 1 long wall + area of 1 short wall ≈ 18.34m²
Cost of covering with wall paper:
Area of 1 roll = 52cm * 10m = 0.52m * 10m = 5.2m²
No of rolls to cover 18.34m² = 18.34m²/5.2m² ≈ 3.5 rolls
Cost of 1 roll = $10
Cost of 3.5 rolls = 3.5*10 = £35
Total cost required = £9.6 + £35 = £44.6
£44.6 is less than the budget of the tenant (£75).
Therefore, the tenant can decorate the room with the set budget.
A standard deviation is 2500 miles, so the range of 25,000 to 37,500 is 2 standard deviations below, and 3 standard deviation above the mean of 30,000.
We aren't assuming anything about the distribution, but we sort of have to assume a normal distribution in order to answer. When you don't know anything about a distribution, this is generally what you do.
The general rule for standard deviations is:
+/- 1 SD: +/- 34% of population, for a total of 68%
+/- 2 SD: Another 14% in either direction, for a total of 96% of population.
+/- 3 SD, Another 2% in either direction, which pretty much captures the entire distribution (4 standard deviations from the mean is incredibly rare/unlikely)
We have a range of +/- 1 SD, so we know that 68% percent o the tire 'population' is captured in the range. We also have one more standard deviation in both directions, so we add 28% to this number to get 96% of the population. We have a third standard deviation above the mean, so we add another 2% to arrive at 98% of the population.
Answer is 98% of all such tires.
The second choice.................................
We have
<span>3/5=(a+5)/25
3/5=(5/5)*(3/5)=15/25
therefore
15/25=</span>(a+5)/25<span>
15=a+5------------------------ > a=10
the answer is the option </span>a = 10
Base in your diagram which shows the top view of a prism sitting upright on one of its trapezoid bases and the height of the prism is 10cm. The surface area base on my calculation is 124cm^2. I hope i answered your question correctly
