[tex](-1)+(-3)=-4[/tex]
Step-by-step explanation:
We were originally on -1.
But we jumped to -4.
-4 is 3 spaces to the left of -1.
In other words, we subtract 3 into -1.
Another way of saying this is that we added -3 to -1.
Therefore, our equation is:

Round 630,379,982 to the nearest hundred thousand
Answer:
630,400,000
Step-by-step explanation:
630,379,982
The 3 above that is bold, between the 0 and the 7, is in the hundred thousands place.
To round to a place, change all digits to the right of that place to zero. If the digit immediately to the right is 0 through 4, you're done. If the digit immediately to the right is from 5 to 9, then you raise the digit you are rounding to by 1.
Step 1. Make all digits to the right of the hundred thousands digit 0.
630,300,000
Step 2. Since the digit immediately to the right of the hundred thousands digit was a 7, which is from 5 to 9, the digit we are rounding to goes up by 1. The 3 becomes 4.
630,400,000
Answer: 630,400,000

Answer: f(x) = -2X + 5
Step-by-step explanation:
You know that there is a strong correlation between the consumption of ice cream and body weight. The Pearson's r = 0.78. You also know that the average consumption of ice cream per week is five grams with a standard deviation of 1.5 grams. The average weight is 65 kg with a standard deviation of 15 kg. What is the formula of the regression line?
Answer:
y = 7.8x + 26
Step-by-step explanation:
Given the following :
Pearson's r = 0.78
Average consumption of ice cream = 5 grams per week (m) with Standard deviation (sd) = 1.5 grams
Average weight = 65 kg with standard deviation of 15kg
Formular for the regression line :
General regression formula :
y = mx + c
y = predicted variable ; m = slope or gradient ; x = predictor variable ; c = intercept
Gradient (m) = change in y / change in x
m = (sd y / sd x) * r
m = (sd weight / sd ice cream) × r
m = (15 / 1.5) × r
m = 10 × 0.78 = 7.8
Intercept:
mean of weight(y) - [Slope×mean of icecream(x)]
65 - [7.8 × 5]
65 - 39 = 26
Hence,
y = 7.8x + 26

Given
Grape = 15
Cherry = 7
Lemon = 3
Strawberry = 5
Total = 30
Required
Determine the probability of picking a strawberry
The probability of drawing a strawberry is calculated by dividing the number of strawberry by the total number of fruits as follows;
[tex]Probability = \frac{Strawberry}{Total}[/tex]
Substitute 5 for Strawberry and 30 for Total
[tex]Probability = \frac{5}{30}[/tex]

Dan is 5 years older than David. Bridget is 8 years younger than David. If the total of their ages is 57, how old is the eldest of them
Answer:
The oldest person is 25 years old
Step-by-step explanation:
Represent David's age by d.
Then Dan's age is d + 5, and Bridget's is d - 8.
The sum of these three ages is 57:
d + (d + 5) + (d - 8) = 57
This simplifies to
3d - 3 = 57, or 3d = 60. Then d must be 20.
David is 20, Dan is 25 (5 years older than David), and Bridget is 12 (8 years younger than David).
Check: Do these three ages add up to 57?
20 + 25 + 12 = 57 YES\
The oldest person is 25 years old. That's Dan's age.
give an example of a set of five different numbers whose mean is 290
Answer:
200,300,290,320,340
Step-by-step explanation:
If the mean of five numbers = 290
Then the total sum of the five numbers should be= 290*5
= 1450
an example of a set of five different numbers whose mean is 290
= 200,300,290,320,340
Summation of the above
=( 200+300+290+320+340)
= 1450
So the above set of numbers is a good example of a set of five different numbers whose mean is 290

Jen classifies the number 4.567 as an irrational number because it does not repeat. Is Jen correct? Explain.
Answer: Jen is wrong about her classification.
Step-by-step explanation:
First of all, we know that the definition of an irrational number is that they are numbers that cannot be represented by a simple fraction and that they are never repeating decimals and they never end.
So, considering this, Jen is wrong because, yes it does not repeat but it DOES END unless it is not written in this problem that it continues on irrationally like pi. Hence, this number is not irrational.
The Jen classifies the number 4.567 as an irrational number is false.
It is required to find the number is rational and irrational numbers.
What is real number?Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
Given :
Jen's argument
We have
4.567 as an irrational number
The above claim is false because
4.567 =
4567/1000
When we divide the above number in the form of p/q and q≠0 then then number is rational number.
Therefore, the Jen classifies the number 4.567 as an irrational number is false.
