Answer:
it should be 25
Step-by-step explanation:
£500 = 500p
500 ÷ 20 = 25
Answer:
mean = 85, standard deviation = 3.5
Step-by-step explanation:
The empirical rule states that for a normal distribution, 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviation of the mean and 99.7% falls within three standard deviation of the mean.
From the diagram since the shaded are is approximately 95% of the data. Hence 95% falls within two standard deviations of the mean.
σ = standard deviation, μ = mean
Hence; μ ± 2σ = (78, 92)
μ - 2σ = 78 (1);
μ + 2σ = 92 (2)
Adding equation 1 and 2, gives 2μ = 170
μ = 85
μ - 2σ = 78
85- 2σ = 78
2σ = 7
σ = 3.5
Given:
rectangular prism = 28 cubic cm
convert to square based or cube
volume of rectangular prism = length * width * height
volume of a cube = a³
√28 = <span>3.03658897188
</span>
Amita can use 3 possible molds that are square based.
Answer:
3/4
Step-by-step explanation:
2/3 = 4/6 so 5/6 plus 4/6 = 1 3/6 then divide by 2, it will give u 0.75 in decimal form which is simplifyed to 3/4, so 3/4 is the answer.
The region that contains the most dispersed data is between the upper quartile and the median.
<h3>Which region contains the most dispersed data?</h3>
A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers.
On the box, the first line to the left represents the lower quartile. The next line on the box represents the median. The third line on the box represents the upper quartile.
- Difference between the lower quartile and the median : 300 - 275 = 25
- Difference between the upper quartile and the median : 340 - 300 = 40
- Difference between the upper quartile and the maximum : 355 - 340 = 15
- Difference between the minimum and the lower quartile : 275 - 250 = 25
