I can’t answer without a visual representation of the spinner, sorry
3+9= 12 12x7=84 84-21=63
so it is 21+63
550+ 3+600 -250=
add the finance charges and the purchases and subtract the payment
1153-250=
903
Answer:
- area of rectangle: 48 cm²
- area of triangle: 18 cm²
- shaded area: 30 cm²
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width.
... A = LW
For your rectangle, the overall area is ...
... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area
___
The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...
... A = (1/2)bh
... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area
___
The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...
... shaded area = rectangle area - triangle area
... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area
Answer:
Option A)
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is
Option A)
Confidence interval decreases
