Answer:
D. Rectangle
Step-by-step explanation:
If you cut the pyramid with a plane parallel to the base, a square is obtained. If the plane is perpendicular to the base, you can obtain two different figures; if the plane passes through the vertex, a triangle is obtained, but if it doesn't pass through the vertex, a trapezoid is obtained.
6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
Answer:
£124
Step-by-step explanation:
first of all, you're meant to add all the figures given on the pie chart, which is 29+137+58+62+74 and that will give you a total of 360 degrees
so, you say 360 degrees is equal to the total amount of money he spent, which is £720, what about 62 degrees
therefore, you just do (62×720)÷360
that will give you £124

See explanation below
Step-by-step explanation:
We need to define the null hypothesis and the alternative hypothesis.
The null hypothesis is the hypothesis that states that the population results are actually what they claimed to be.
So, in this case, the null hypothesis (H₀) would be:<u> P(student buys a hard copy) = 0.60 P(student prints book from the web) = 0.25, P(student reads book online) = 0.15</u>
The alternate hypothesis states that the results were not the expected ones, in this case, any alternate hypothesis with different probabilities of any of the three cases will do.
<u>Hₐ= The percentages of students for any of the three cases is different (either greater or lower)</u>
