What two numbers multiply to 18 but add to get -5?
Answers
-9*-2 wont work because -9+-2 gets you -11
-6*-3 wont work because -6+-3 gets negative nine
i dont think there is one honestly. ive sat here and tried them all
2 and 9 6 and 3 and 18 and 1
Final answer:
To find two numbers that multiply to 18 and add to -5, consider the factors of 18 and check which pair meets the conditions. The numbers that satisfy the given conditions are -9 and -2.
Explanation:
To find two numbers that multiply to 18 and add to -5, we can use the factoring method. By considering all the possible factors of 18, we can find the pair of numbers that satisfy the given conditions. The two numbers that meet these criteria are -9 and -2.(-9 * -2 = 18, -9 + -2 = -11)

The probability of pulling one marble out of a jar containing 49 red marble and 1 blue marble is 1 / 50, hence it is an unlikely event, so option D is correct.
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a value between 0 and 1.
Given:
Pull a blue marble at random out of a jar with 49 red marbles and 1 blue marble,
Calculate the probability of pulling blue marble as shown below,
Probability = number of blue marble / total marble
Probability = 1 / 49 + 1
Probability = 1 / 50
As you can see here, the probability of the event pulling the blue marble in the jar is not dependent on the probability of pulling the red marble as there is only one marble so, it is an example of an unlikely event.
We know that the probability of an unlike event is between 0 and 1 / 2 and here probability is 1 / 50,
Thus, it is an unlikely event.

The measure of the central angle is within 0 to π radians.
Equation
An equation is an expression that shows the relationship between two or more variables and numbers.
Angle in radian = angle in degrees * π / 180
Given that the angle = 85°, hence:
Angle in radian = 85 * (π/180) = 0.472π rad
The measure of the central angle is within 0 to π radians.

Which of the choices below best describes how to measure the spread of this data?
A. Both spreads are best described with the IQR.
B. Both spreads are best described with the standard deviation.
C. The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
D. The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answers
Answer:
C. The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
If data is normally distributed we use Standard deviation otherwise we use Interquartile Range (IQR) for measuring the spread.
Further, data is said to be normally distributed if Mean = Median = Mode.
So, High School data is normally distributed but College data is not.
So, We measure the spread of College data by IQR and High School data by Standard Deviation.
Thus, Option C is the only correct option.

Answer:
Oil changes = 5
Vincent = 10 oil changes
Warren = 10 oil changes
Step-by-step explanation:
Vincent = 5 + h
Warren = 2h
Where,
h = number of oil changes
How long will that take?
Vincent = Warren
5 + h = 2h
5 = 2h - h
5 = h
h = 5
Number of oil changes = 5
How many oil changes will Vincent and Warren each have done?
Vincent = 5 + h
= 5 + 5
= 10 oil changes
Warren = 2h
= 2(5)
= 10 oil changes
