Answer:
1/24
Step-by-step explanation:
The probability of the dice landing with a 5 up is 1/6; that of drawing a heart is 13/52, or 1/4.
The joint probability of these two events (events happening simultaneously) is
(1/4)(1/6) = 1/24
Answer:
8.3 cm
Step-by-step explanation:
1. Find the volume of the small cylinder (volume of a cylinder = πr² · h)
π(4.5²) · 17 = 1080.945 cm³
2. Set up the equation to find the volume of the big cylinder
πr² · 5 = 1080.945
3. Divide both sides by 5
πr² = 216.189
4. Divide both sides by π (3.14)
r² = 68.85
5. Square root both sides
r = 8.3 cm (rounded to the nearest tenth)
Answer:
Step-by-step explanation:
Given that a marketing research firm is estimating which of two sodas (A or B) college students prefer.
Sample size of 75 was taken at random.
Since sample size is sufficiently large i.e. >30, and also since samples are taken at random, we can assume that sample proportion
p= follows a normal distribution with mean = 0.6 and variance = npq = 75(0.6)(0.4)
Yes, this sample is large enough to calculate a confidence interval.
The number of jolly rangers candy she has is 22. The number of twix bars she has is 11.
<h3>What are the linear equations that represent this question?</h3>
j + t = 33 equation 1
4t = 2j
j = 2t equation 2
Where:
j = number of jolly rangers
t = j = number of twix
<h3>How many twix candies does Julianna have?</h3>
Substitute for j in equation 1 using equation 2
2t + t = 33
3t = 33
t = 11
<h3>How many jolly candies does Julianna have?</h3>
Subsitute for t in equation 2
j = 11 x 2 = 33
