Answer:
Step-by-step explanation:
1) A = x
Flower garden is in rectangular shape. In rectangle, opposite sides are equal.
2) The entire garden is in rectangular shape. In rectangle, opposite sides are equal.
B + x+ 4 = 10x + 6
Take x and 4 to other side to find the value of B. When taking to other side of equal to sign, the sign of x and 4 will change
B = 10x + 6 - x - 4
B = 10x - x + 6 - 4 {Combine like terms}
B = 9x + 2
3) C + x -2 = 5x -3
C = 5x - 3 - x +2
C = 5x -x - 3 + 2
C = 4x - 1
4) Area of Vegetable garden = length * width
= (5x - 3) * (9x + 2)
Use FOIL method
= 5x *9x + 5x*2 + (-3)*9x + (-3)*2
= 45x² + 10x - 27x - 6
= 45x² - 17x - 6
Answer:
1.1kg
Step-by-step explanation:
weight of fruit = 2kg
percentage of weight of fruit = 100%
percentage of weight of pineapple = 25%
weight of pineapple = 25/100 ×2
= 0.5kg
percentage of weight of bananas = 10%
weight of bananas = 10/100 × 2
= 0.2kg
weight of apples = weight of fruit - ( weight of pineapple + weight of bananas)
= 2kg -(0.5 + 0.2)kg
= 2kg -0.7kg
= 1.3kg
The weight of apples than bananas emma bought was =1.3kg-0.2kg
=1.1kg
therefore emma bought 1.1kg of apples than bananas.
Answer:
True, this is the meaning of the z-score. Z = 0.65 means that the raw score is 0.65 standard deviations above the mean.
Step-by-step explanation:
The Z-score measures how many standard deviations a raw score is from the mean.
For example, a z-score of -2 means that the raw score is 2 standard deviations below the mean.
Another example, a z-score of 2 means that the raw score is 2 standard deviations above the mean.
If z= 0.65, then the raw score is 0.65 standard deviations above the mean.
True, this is the meaning of the z-score. Z = 0.65 means that the raw score is 0.65 standard deviations above the mean.
N = 4
(3)(4)-(2+4) = 12 - 6 = 6
