What can be used to predict diameter, given family income
We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.
i.e. --- equation of line of best fit
In this case;
<em>When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)</em>
Answer:
Step-by-step explanation:
Adjacent angles of parallelogram are supplementary.
∠A + ∠D = 180
Divide both sides by 2
∠A + ∠D = 90
∠PAD + ∠ADP = 90 --------------------(I)
IN ΔPAD,
∠PAD + ∠ADP + ∠APD = 180 {angle sum property of triangle}
90 + ∠APD = 180 {from (I)}
∠APD = 180 - 90
∠APD = 90
∠SPQ = ∠APD {vertically opposite angles}
∠SPQ = 90°
Similarly, we can prove ∠PQR = 90° ; ∠QRS = 90° and ∠RSP = 90°
In a quadrilateral if each angle is 90°, then it is a rectangle.
PQRS is a rectangle.
It's going down by five but I'm sure on the last one..but to help add a zero like if it 0.5 it would be 0.50 that should help.
Answer:
Number of full size cars = 900
Step-by-step explanation:
The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are there in both ratios , we need to make the number in the ratio for compact cars to be the same.
Multiply by 8 on numerator and denominator
Multiply numerator and denominator by 5.
Ratio of medium, compact and full size are in ratio 56,40,45.
Total number of cars =2820.
(56 + 40 + 45)x = 2820
x =
x = 20
Number of full size cars = =900
Answer:
The answer is 13 ladies and 6 men
Step-by-step explanation:
The easiest way to get this is you have 19 people and take away 7 as they are ladies and you have 12 divide that by 2 getting you 6, then add the 7 ladies you took away at the start and add em to the 6 you have now. and thats how you get the answer.
Hope this helps and don't forget to hit that heart :)
