in the top left box there would be the number 8 because there are 8 boys who have pets
in the top right box there would be the number 5 because there are 5 boys who don’t have pets
in the bottom left box there would be the number 11 because there are 11 girls who have pets
in the bottom right box there would be the number 6 because there are 6 girls who don’t have pets
Answer:A or D
Step-by-step explanation:
Length times width equals area so
Area divided by length equals width
50 dived by 25 equals 2
Answer:
x = 2; y = 3; z = 1
Step-by-step explanation:
For the first fertilizer (A) we can form the equation:
y + 2z = 5
For the second fertilizer (B) we can form the equation:
x + 2y + 5z = 13
For the third fertilizer (C) we can form the equation:
x + 2z = 4
solving simulteneously:
y = 5 - 2z
x = 4 -2z
Substituting (i) and (ii) into (2)
4 - 2z + 10 -4z + 5z = 13
14-z =13, therefore z = 1
substituting z into (i) and (ii)
y = 3
x = 2
Step-by-step explanation:
R = x²/y
Substitute
R = (4.8×10⁵)²/2.8×10⁴
= 4.8²×10¹⁰/2.8×10⁴
= 23.04×10¹⁰/28000
Answer:
The correct statements are b, c and e.
Step-by-step explanation:
Consider the dot plot for Noah and Jada's score in the trivia game.
From the dot plot it is quite clear that the data form a bell-shaped curved or a normal curve.
For the normal distribution:
Mean = Median = Mode
Noah's mean score = 5
Jada's mean score = 3
The standard deviation of a data set is the measure of dispersion of the observations of that data set from their mean.
On closely studying the graphs we can see that the Noah and Jada's scores are almost at a same distance from the mean, i.e. the spread of Noah's score is same as the spread of Jada's score.
So, the correct statements are:
b. The standard deviation of Noah's scores is equal to the standard deviation of Jada's scores.
c. The mean of Noah's scores is greater than the mean of Jada's scores.
e. Using only Noah's scores, the mean is equal to the median
