Answer:
The expected combined weight of the child's lollipop and two chocolate bars is 5.5 oz.
Step-by-step explanation:
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Addition of normal variables:
The mean is the sum of the means.
Find the expected combined weight of the child's lollipop and two chocolate bars.
Child lollipop: Mean 1.5 oz
Chocolate bars: Mean 2 oz
One lollipop and 2 bars combined
The mean will be 1.5 + 2*2 = 5.5 oz
The expected combined weight of the child's lollipop and two chocolate bars is 5.5 oz.

When the swimmers first arrived at the pool, the temperature of the water was only 72.5 degrees. By the time the first race started, the temperature had gone up 5.6 degrees. What was the temperature of the water when the first race started?
Answer:
The temperature of the water when the first race started was 78.1 degrees
Step-by-step explanation:
Addition
The temperature of the water of a pool was 72.5 degrees when the swimmers first arrived.
By the time when the first race started, the temperature had increased by 5.6 degrees.
To find the temperature at that very moment we have to add 72.5 degrees + 5.6 degrees = 78.1 degrees
The temperature of the water when the first race started was 78.1 degrees
Is 23, 11, 25, 19 a composite number?
Answer:
23 is a prime number. 11 is a prime number. 25 is a composite number. and 19 is a prime number.
Step-by-step explanation:
Hi there!
23 is a prime number because it has only two factors - 1 and itself.
Remember, a factor is a number that a number can be evenly divided by. So 3 is not a factor of 23.
11 is prime as well.
25 is a composite number because it's last digit is 5. If a number's last digit is 5, then it's divisible by 5. Therefore, it's composite.
19 is a prime number.
Hope you find this helpful!

If the slope of a proportional relationship is 3 what is the equation that represents that line
Answer:
y = 3x
Step-by-step explanation:
A proportional function has the equation
y = kx, where k is the constant of proportionality and also the slope of the line.
Answer: y = 3x
The equation that represents the line whose slope of proportional relationship is 3 is; y = 3x.
The slope of the proportional relationship as given is 3.
In essence, slope, m = 3.However, the equation of the line which represents a proportional relationship usually takes the form; y = Mx.
Since, slope, m = 3.
The equation of the line is; y = 3x.

C) 480 - x = number of adults
D) 360 adults attended.
E) 200 children attended.
Answer:
The answer is C and D
Step-by-step explanation:
