Hello!

Find the cost of each individual item.

1.28 / 2 = 0.64

Each roll of tape costs $0.64.

0.87 / 3 = 0.29

Each notebook costs $0.29.

Each highlighter costs $1.59.

1.98 / 2 = 0.99

Each pen costs $0.99.

One roll of tape is $0.64, two notepads are $0.58 two highlighters cost $3.18, two pens are 1.98.

Add them up: .

0.64 + 0.58 + 3.18 + 1.98 = 6.38

ANSWER:

You would pay B. $6.38.

We have to determine what it costs for one single item and then divide or multiply by the quantity needed.

1 roll Tape= $1.28÷2= $0.64

2 rolls Notepads= 0.87÷3= 0.29x2= $0.58

2 Highlighters= $1.59x2= $3.18

2 Pens= $1.98

Add these totals:
+0.64
+0.58
+3.18
+1.98
=$6.38

ANSWER: B) $6.38

Hope this helps! :)

An axis of symmetry passes through the vertex and is perpendicular to the base. Then the correct options are B, C, and E.

<h3>What is a rectangular pyramid?</h3>

Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.

The base of the pyramid is a rectangle that is not a square.

The pyramid has two planes of symmetry.

An axis of symmetry passes through the vertex and is perpendicular to the base.

An angle that measures 90° is an angle of rotation for an axis of symmetry for the pyramid.

Then the correct options are B, C, and E.

There is a bag filled with 3 blue, 4 red and 5 green marbles. A marble is taken at random from the bag, the colour is noted and

Sauron [17]

Calculate Total marbles:

Total marbles = Blue + Red + Green

Total marbles = 3 + 4 + 5

Total marbles = 12

Probability of a green = 5/12

Probability of not green = 1 - 5/12 = 7/12

To get exactly one green in two draws, we either get a green, not green, or a not green, green

First Draw Green, Second Draw Not Green

1st draw: Probability of a green = 5/12

2nd draw: Probability of not green = 7/11 <-- 11 since we did not replace the first marble

To get the probability of the event, since each draw is independent, we multiply both probabilities

Probability of the event is (5/12) * (7/11) = 35/132

First Draw Not Green, Second Draw Not Green

1st draw: Probability of not a green = 7/12

2nd draw: Probability of not green = 5/11 <-- 11 since we did not replace the first marble

To get the probability of the event, since each draw is independent, we multiply both probabilities

Probability of the event is (7/12) * (5/11) = 35/132

To get the probability of exactly one green, we add both of the events:

First Draw Green, Second Draw Not Green + First Draw Not Green, Second Draw Not Green

35/132 + 35/132 = 70/132

SO THE ANSWER IS 35/66

Based on a poll, 40% of adults believe in reincarnation. Assume that 8 adults are randomly selected, and find the indicated prob

Veronika [31]

Answer:

The probability under the given conditions is found:

P(7) = 0.079

Step-by-step explanation:

Let x be the number of adults who believe in reincarnation.

Adults randomly selected = 8

percentage of adult believe in reincarnation = 40% = 0.4

x follows binomial distribution:

P(x) = $\left(\begin{array}{ccc}n\\x\end{array}\right) (p)^x(1-p)^{n-x}$

where

n= total people random people selected = 8,

x = selected for the part = 7,

p = probability given = 0.4

P(7) = $\left(\begin{array}{ccc}8\\7\end{array}\right) (0.4)^7(1-0.4)^{8-7}$

P(7)= (8)(0.0164)(0.6)

P(7) = 0.07872

Rounding off to 3 decimal positions

P(7) = 0.079
