Jesse collected 42 football cards and 28 basketball cards simpfly the ratio of baseball cards to football cards in his collection
Answers
The ratio of basketball card to football cards is 2 : 3.
What is the ratio?
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.

28 : 42
7 into 28 is 4 and 7 into 42 is 6
28 : 42 = 4 : 6
2 into 4 is 2 and 2 into 6 is 3
28 : 42 = 4 : 6 = 2 : 3
So the simplified ratio of baseball cards to football cards is 2 : 3.
I hope this helps.

Answers
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%.
How to obtain probabilities using the normal distribution?
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 z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.
- Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.
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%.

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:
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
