Answer:
A. The mean will increase.
Step-by-step explanation:
The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
84 + 75 + 76 + 80 + 48 + 75 = 438
438 / 6 = 73
mean = 73
The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.
84 + 75 + 76 + 80 + 75 = 390
390 / 5 = 78
NEW mean (without the outlier) : 78
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
y=41
Step-by-step explanation:
Let us start by writing an equation. <em>4 plus y divided by 5 equals to 9</em> :
Great! Now let us solve for the variable, <em>y</em>, by isolating the terms:
