The ratio of basketball card to football cards is 2 : 3.
A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now it is given that,
Number of football cards = 42
Number of basketball cards = 28
Hence,
Ratio of basketball cards to football cards = Number of basketball cards/Number of football cards
⇒Ratio of basketball cards to football cards = 28/42
⇒Ratio of basketball cards to football cards = 2/3
⇒Ratio of basketball cards to football cards = 2:3
Therefore,The ratio of basketball card to football cards is 2 : 3.

b. What is the probability that a randomly selected person spent between $9 and $21?=0.3608
The probabilities regarding a person spending are given as follows:
a) More than 28: 0.2033 = 20.33%.
b) Between 9 and 21: 0.3608 = 36.08%.
The z-score of a measure X of a variable that has mean symbolized by and standard deviation symbolized by is obtained by the rule presented as follows:
The mean and the standard deviation for this problem are given as follows:
The probability of a person spending more than 28 is one subtracted by the p-value of Z when X = 28, hence:
Z = (28 - 23)/6
Z = 0.83
Z = 0.83 has a p-value of 0.7967.
1 - 0.7967 = 0.2033 = 20.33%.
The probability of spending between 9 and 21 is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 9, hence:
Z = (21 - 23)/6
Z = -0.33
Z = -0.33 has a p-value of 0.3707.
Z = (9 - 23)/6
Z = -2.33
Z = -2.33 has a p-value of 0.0099.
Hence:
0.3707 - 0.0099 = 0.3608 = 36.08%.

find the product
(5n+6)(5n-5)
The solution of expression after multiplying is,
⇒ 25n² + 5n - 30
We have to given that,
To multiplying polynomials is,
⇒ (5n + 6) (5n - 5)
Now, We can multiply as,
⇒ (5n + 6) (5n - 5)
⇒ 5n × 5n + 5n × - 5 + 6 × 5n + 6 × - 5
⇒ 25n² - 25n + 30n - 30
⇒ 25n² + 5n - 30
Therefore, The solution is,
⇒ 25n² + 5n - 30

Answer:
The answer is 150
Step-by-step explanation:
If you take 20 percent of 144 you get 28.8 but then you must subtract from 144 that leave you with 150.2 the 0.2 dosent matter
Answer:
NO Slope
Step-by-step explanation:
slope of the line passing through the points (5, 4) and (5, -5)
slope = y2 - y1 = -5 - 4 = -9
x2 - x1 5 - 5 0
see attached.
in this graph of a line x = 5, no matter what the value of y is.
the horizontal change is 0 and the vertical change is any y value
therefore, there is NO Slope
