Answer:
a. The probability of taking out a purple flower is 0.47.
b. The probability that out of a sample of 5 flowers at least 3 flowers are yellow 0.56.
c. The standard deviation of the distribution for proportion of yellow flowers is 0.22.
d. The probability that out of the 263 samples, at most 150 of them are yellow is 0.90.
Step-by-step explanation:
I=PRT
I=interest
P=initial amount
R=rate in decimal
T=time in years
given
P=5523
R=4.99%=0.0499
T=7
I=(5523)(0.0499)(7)
I=1929.1839
round
$1929.18 interest earned
Answer:
Step-by-step explanation:
If A = (-3,-1) and B = (4,4), the slope of AB is
Two perpendicular lines have slopes that have product of -1:
The equation of the line BC with slope -1.4 and passing through the point B(4,4) is
To calculate the slope containing two points, we can use that formula:
"m" represents the slope and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 2 uc.
Answer:
25 cups of tea
Step-by-step explanation:
On the x-axis, we have the number of cups of coffee plotted against the number of cups of tea which are plotted on the y-axis to represent the daily sales goals.
From the graph, when 20 cups of coffee are sold (x = 20), a corresponding sales of 25 cups of tea (y = 25) would be sold as well to meet the sales goal.
Therefore, when employees sell 20 cups of coffee, 25 cups of tea must be sold to meet their goal.
