P’(rolling a number less than five and landing on tails)

Mathematics
1 answer:
Ksenya-84 [330]3 years ago
3 0

Answer:

P’(rolling a number less than five and landing on tails) = 1/3

Step-by-step explanation:

dice has 6 numbers and you only want 4 of them, so you have a 4 in 6 chance of doing that which is equal to 4/6 or 2/3

a coin has 2 side so the chance of getting tails is 1 in to or 1/2

therefore the probability of getting a number less than 5 and a tails is

4/6 times 1/2 = 4/6 x 1/2 = 4/12 = 1/3

or you can do it this way:

2/3 times 1/2 = 2/3 x 1/2 = 2/6 = 1/3

pishuonlain [190]

Answer:The 20th term of the arithmetic sequence is 55

Step-by-step explanation:

A sequence can be described using the rule:

an = –2 + 3(n-1)

Where

an is the value of the nth term of the arithmetic sequence.

- 2 is the first term of term of the sequence.

n is the number of terms in the sequence.

To determine the 20th term, we will substitute n = 20 into the equation. It becomes

a20 = - 2 + 3(20 - 1)

a20 = - 2 + 3×19

a20 = -2 + 57 = 55

Which pyramids with base area B and height h have equal volumes.
Reptile [31]

C and D

the volume ( V) of a pyramid is found using the formula

V = \frac{1}{3} × area of base × height

calculating each of the volumes gives

(A)  V = \frac{1}{3} × 10.5 × 6 = 21 in³

(B)  V = \frac{1}{3} × 3.6 × 8 = 9.6 in³

(C)  V = \frac{1}{3} × 4.2 × 12 = 16,8 in³

(D)  V = \frac{1}{3} × 6 × 8.4 = 16.8 in³

C and D have equal volumes
