Answer:
95%
Step-by-step explanation:
Let the proportion who can swim be denoted by P(S) while the proportion that can whistle be denoted by P(W)
The proportion that can swim and whistle will be P(S and W)
The proportion that can swim or whistle will be P(S or W)
To get the proportion that can swim or whistle will be P(S or W), we use
P(S or W)=P(S)+P(W)-P(S and W)
Given that P(W) is 70%, P(S) is 80% and P(S andW) is 55% then
P(S or W)=80%+70%-55%=95%
Answer:
triangle
Step-by-step explanation:
Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons
