Using the probability of complementary events, it is found that there is a 0.75 probability of any other suit.
What is the probability of complementary events?When two events are complementary, the sum of their probabilities are 1.
In this problem, a diamond card and a card for any other suit are complementary events, hence the equation is:
0.25 + p = 1
p = 0.75.
Thus, there is a 0.75 probability of any other suit.

Suzanne bought a sweater at the sale price of 87.50. Originally, the sweater sold for $140. What was the percent discount? ( please help me! )
Answer:
37.5%
Step-by-step explanation:
the savings on the sweater is 140-87.50, or 52.50
you could create a proportion based on the statement:
52.50 is what percent of 140?
is/of = 'x'/100
52.5/140 = x/100
cross-multiply to get:
140x = 5250
x = 5250/140
x = 37.5

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?
Answer:
The range is 0-25 feet
Step-by-step explanation:
Mathematically, when we are talking of the range, we are simply referring to the values at the boundaries.
This refers to the y-axis values. That is the values of the dependent variable
If we are to plot the graph, we will have the time on the x-axis while the amount of time spent in air would be on the y-axis
The base height is from the ground which is marked 0 feet to a maximum height of 25 feet
So the range in the context of this problem is 0-25 feet

Answer:
Five pizzas and twenty five hamburgers.
Step-by-step explanation:
5 (pizzas) times 5 is 25. That would be the total amount of hamburgers, because 5×5=25
30 (total) - the 25 hamburgers= 5 pizzas
Hope this helps
Answer:
Pizza = x
Ham = 5x
x + 5x = 30
6x = 30
x = 5
pizza = 5
ham = 5x5 = 25

Write a quadratic equation with the given solutions below such that the terms of the quadratic contain no common factors.
-3,1
Answer:
x² +2x -3 = 0
Step-by-step explanation:
Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...
0 = (x -(-3))(x -1) = (x +3)(x -1)
In standard form, this is ...
x(x -1) +3(x -1) = 0
x² +2x -3 = 0 . . . . . . the terms have no common factors

Katherine is visiting patients in a hospital. She visits 18 patients in 6 hours. At that rate, how many patients will she visit in 9 hours?
Answer:
Let's find the unit rate first, I like to order my units:
Patients 18 3 patients_________ = ______ = ______________, so 3 patients per hour is the
Hours 6 1 hour-unit rate.
Now let's order them to equal x(unknown patients)/9(hours)
3 patients (x9) x___________ = __________ = 27 patients per 9 hours. So your answer
1 hour (x9) 9is 27 patients.
Answer:
27 patients
Step-by-step explanation:
18patients = 6 hours
18/6 = 3
each hour for 6 hours she attends to 3 patient
6 hours + 3 hours make up 9 hours
since for each hour she attended to three patients we would say
1 hr = 3 patients
1 hr = 3 patients
1 hr = 3 patients
Total: 3 hrs = 9 patients
18 patients + 9 patients = 27 patients
so for 9 hrs Katherine will visit 27 patients.

Answer:
y = 3x + 1
Step-by-step explanation:
m = ( 1 - 4 ) / ( 0 - 1 ) = 3
( 0 , 1 )
y - 1 = 3(x - 0)
y - 1 = 3x
y = 3x + 1
Answer:
y=3x+1
Step-by-step explanation:
Slope is (y2-y1)/(x2-x1)
therefore slope =
(1-4)/(0-1)
-3/-1
m=3
therefore the equation is
y-y1=m(x-x1)
y-4=3(x-1)
y-4=3x-3

Adam drove 918 miles on 27 gallons of fuel. at this rate, how many gallons of fuel would it take to drive 510 miles.
Answer: 15 gallons
Step-by-step explanation:
Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons
918/27 = 510/x
Cross multiply and you get 918x = 13770
and you get x = 15
Or you could do 918 miles / 27 gallons = 34 miles / gallon
and divide the 510 miles of distance by how many miles per gallon, so
510 / 34

25º
65º
85º
115º
Answer:
65
Step-by-step explanation:
It’s 65 because 65+35=100 then u add 80 to get 180
The measure of the third angle in the triangle is 65°. The correct option is B.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that Triangle P Q R. Angle Q is 80 degrees and angle P is 35 degrees. Triangle W X Y. Angle W is 35 degrees and angle X is 80 degrees.
The third angle will be calculated as:-
Angle = 180 - 80 - 35
Angle = 65
Therefore, the measure of the third angle in the triangle is 65°. The correct option is B.
