Answer: 0.58

Step-by-step explanation:

Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)

Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)

Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )

STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)

A three-dimensional figure with one circular or elliptical base and a curved surface that joins the base to the vertex is called

babunello [35]

Answer:

a cone

Step-by-step explanation:

If the base is circular, then the cone is said to be a "regular" or "circular" cone, much like an ice cream cone.

If the base is elliptical, then it becomes an "elliptical" cone.

Both shapes can be right (where the perpendicular line dropping from the vertex lands on the exact center of the base) or oblique (when the line dropping from the vertex doesn't land on the center of the base)

This week, 957 people went to the beach. Last week, 1,207 people went to the beach. The number of people who went to the beach

kati45 [8]

Answer:

Less than 25%

Step-by-step explanation:

1. Find the difference of the two numbers: 1,207 - 957 = 250

decrease = original number - new number

2. Then, divide the decrease by the original number

250/1,207 = 0.207

3. Multiply the answer by 100 to get the percentage

0.207 x 100 = 20.7%

Therefore, the number of people fell by 20.7%

Hence, the answer is less than 25%

A fisherman can row upstream at 2 mph and downstream at 8 mph. He started rowing upstream until he got tired and then rowed down

slega [8]

<h3>Answer: 16 miles</h3>

==========================================================

Explanation:

x = time in hours spent going upstream

5-x = remaining time in hours spent going downstream

Those two quantities add to 5 hours total.

Let's find the expression for how far the fisherman went upstream

distance = rate*time

d = r*t

d = 2x

Do the same for the downstream portion

d = r*t

d = 8(5-x)

d = 40-8x

The values of d refer to the same distance because he came back to the starting point.

Set those right hand sides equal to one another and solve for x.

2x = 40-8x

2x+8x = 40

10x = 40

x = 40/10

x = 4

5-x = 5-4 = 1

He spent 4 hours going upstream, and the remaining 1 hour coming back downstream.

--------------

If he spent 4 hours going upstream at 2 mph, then he traveled d = r*t = 2*4 = 8 miles.

The remaining 1 hour going downstream at 8 mph means he traveled d = r*t = 8*1 = 8 miles, which matches with the previous result. This confirms we have the correct one-way distance of 8 miles.

Therefore, the total round trip distance is 2*8 = 16 miles
