CIs store sells different colours of cell phones. In a month, they sold cell phones valued
to R48 560.
1.1.1
If red, silver and black cell phone were sold in the ratio of 1:35
respectively. Determine (nearest on hundred rand) the amount of silver cell
phones sold.
(4
Answers
Answer:
The amount of silver phones sold in the month is R16 186.67
Step-by-step explanation:
In the given month, the colours of phones sold were red, silver and black.
Total amount of phones sold = R 48 560
Ratio of phones sold = 1:3:5
Sum of the ratio = 1 + 3 + 5
= 9
i. The amount of red phones sold = [tex]\frac{1}{9}[/tex] x 48 560
= 5 395. 56
The amount of red phones sold in the month is R5 395.56
ii. The amount of silver phones sold = [tex]\frac{3}{9}[/tex] x 48 560
= 16 186.67
The amount of silver phones sold in the month is R16 186.67
iii. The amount of black phones sold = [tex]\frac{5}{9}[/tex] x 48 560
= 26 977.78

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Katie selects a simple random sample of 25 students at her large school and finds that 5 of them are planning to try out for the soccer team next year
p= the proportion of all students at her school who plan to try out for the soccer team next year
The condition that Katie has failed to meet is the first one, which states that the sample size should be large enough.
Specifically, the condition is that the sample size n should be greater than or equal to 30.
In this case, Katie only has a sample size of 25, which is less than 30.
This means that the sample may not be large enough to accurately estimate the population proportion and construct a reliable confidence interval.
Hence, n ≥ 30 is the condition for this procedure has she failed to meet

You have two coupons, one is for $25 off and the other is for 25% off. When would you use the $25 off coupon? When would you use the 25% off coupon? When would it not matter which coupon you use?
Answers
Answer:
If I had two coupons, one for $ 25 off and the other for 25% off, to determine when I would use the $ 25 off coupon and when I would use the 25% off coupon, and when it would not matter which coupon I would use, I must carry out the following reasoning:
The $ 25 off coupon is a flat coupon, that is, it does not adapt to the price of the thing to be paid, but rather maintains its value constantly. Therefore, its utilization will be higher if those $ 25 represent a high value compared to the initial price of the product: if the thing is worth $ 50, a $ 25 off coupon represents half its value, while if the thing is worth $ 500, that same coupon will only represent 5% of it. Therefore, I would use the coupon for things that are worth between $ 25 and $ 99.
Instead, the 25% off coupon is a variable coupon, which is adapted according to the value of the product. In other words, a discount will always be made for 25% of said value: if the product is worth $ 80, the discount will be $ 20 (80 x 0.25), while if the product is worth $ 1,000, the discount will be $ 250 (1000 x 0.25 ). Therefore, I would use the coupon for products with a price greater than $ 100, that is, from $ 101 and up.
Finally, since 25% of $ 100 is $ 25, if you buy something of that value, it would be indistinct to use either of the two coupons.

Round your answer to the nearest whole number.
Answers
Answer:
Volume of cone = 418.67 cm³ (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 5 cm
Height of cone = 16 cm
Find:
Volume of cone
Computation:
Volume of cone = [1/3][π][r²][h]
Volume of cone = [1/3][3.14][5²][16]
Volume of cone = [1/3][3.14][25][16]
Volume of cone = [1/3][3.14][400]
Volume of cone = [1/3][1,256]
Volume of cone = 418.67 cm³ (Approx.)

The height of 4 ft and a radius of 8 ft. If the center tank is full of heating fuel and develops a leak at the bottom, will the container be able to hold all the heating fuel that leaks out?
Volume of the holding tank= ______ ft^3
Volume of the containment tank= ______ ft^3
Answers
9514 1404 393
Answer:
no
Step-by-step explanation:
The volume of each cylinder is given by ...
V = πr²h
The volume of the holding tank is ...
V = 3.14(6 ft)²(16 ft) = 1808.64 ft³
The volume of the containment is ...
V = 3.14(8 ft)²(4 ft) = 803.84 ft³
__
The containment will not hold all the fuel. The radius of the containment would have to be 12 ft to have the same volume as the holding tank.
