Answer:

See the Venn diagram attached

Numbers given:

Total: 100
Either a cat of a fish: 70
Cat: 46
Cat and fish: 16

Neither a cat or a fish: 100 - 70 = 30

Fish: 70 - (46 + 16) = 70 - 62 = 8

Required probabilities are:

a) P(neither) = 30/100 = 0.3
b) P(f) = (16 + 8)/100 = 0.24
c) P(f not c) = 8/100 = 0.08

Joe is finding the length of a rectangular prism. The volume of the prism is 204 ft3. The width is 3.5 ft, and the height is 5 f

zmey [24]

Answer:

B. He added 3.5 and 5 when he should have multiplied them.

Step-by-step explanation:

Let's observe Joe's steps:

- V = lwh

- 204 = 3.5 * (5) * l

Here, * means to multiply, so we're supposed to multiply 3.5 to 5, which would give you the answer 17.5. Unfortunately, look what Joe got: he obtained the value of 8.5, and if we observe, 3.5 + 5 = 8.5.

That's how we know that Joe added instead of multiplied, as he should have done. Thus, the answer is B.

Find the missing side

dybincka [34]

Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

$a^{2} + b^{2} = c^{2}$

Question 7:

$4^{2} + 8^{2} = c^{2}$

16 + 64 = $c^{2}$

80 = $c^{2}$

$\sqrt{80} = \sqrt{c^{2}}$

c = 8.94

Question 8:

$6^{2} + 3^{2} = c^{2}$

36 + 9 = $c^{2}$

45 = $c^{2}$

$\sqrt{45} = \sqrt{c^{2} }$

c = 6.71
