Answer:
3x - y = 22
Step-by-step explanation:
The abcisssa is known as the x coordinate while the ordinate is the y coordinate
abcissa = x
ordinate = y
“three times the abscissa = 3x
“three times the abscissa decreased by ordinate is expressed as;
3x - y
Is the result is 22, hence;
3x - y = 22
this gives the required expression
Answer:
The correct option is (D).
Step-by-step explanation:
The data for the number of points scored by Reuben in the first five basketball games of a season are:
A = {23, 15, 28, 19, 25}
And the data for the number of points scored by Reuben in the next five games is:
B = {23, 30, 15, 22, 26}
For the first data there are only 5 observations to draw conclusions about the spread of the data and the peak of the distribution curve.
But after the next five games played by Reuben, there are 10 observations to draw conclusions.
The spread of the data is dependent upon the sample size.
Larger the sample size the smaller is the spread. And hence the distribution curve will be more peaked.
And smaller the sample size the larger is the spread. And hence the distribution curve will be less peaked.
So, after the next five games the distribution of Reuben's score would become more peaked and less widely spread.
The correct option is (D).
Answer: Greater than
Answer: Greater than
Answer:
n + s = $68.75
Step-by-step explanation:
Amount spent on pizza and soda = $68.75
Number of pizza = n
The soda = s
Then the total amount soe t can be modeled thus :
(number of pizzas + number of soda) = total amount spent
n + s = $68.75
If the price of each slice of pizza and unit of soda was given, we could have been able to calculate the amount spent on each of soda and pizza.
Answer:
x = -5 ±4sqrt(2)
Step-by-step explanation:
(x+5)²=32
Take the square root of each side
Sqrt((x+5)²)=±sqrt(32)
x+5 = ±sqrt(16*2)
x+5 = ±4sqrt(2)
Subtract 5 from each side
x+5-5 = -5 ±4sqrt(2)
x = -5 ±4sqrt(2)
