Answer:
Step-by-step explanation:
The numerator of the rational expression the money he earned for 'x' hours
The rate at which William is paid for each hour in excess of 40 hours 24.
x = 50 hours = (40 + 10 ) hours
The amount paid for excess 10 hours = 24 *10 = 240
Total amount earned for the week = 480 + 240 = 720
Answer:
3/2
Step-by-step explanation:
The equation 3x-2y=4 can be written in the form of y=mx+c where m is the slope and c is the y intercept.
Therefore
2y=3x-4 and dividing both sides by 2 to have y at the LHS
y=3/2x-2
Therefore, 3/2 represents the gradient/slope
Answer:
The minimum sample size needed for use of the normal approximation is 50.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 5
n(1-p) >= 5
In this question, we have that:
p = 0.9
Since p > 0.5, it means that np > n(1-p). So we have that:
The minimum sample size needed for use of the normal approximation is 50.
Answer:
1.2 > 1.13
2.38 > 2.3
1.40 = 1.4
Step-by-step explanation:
Each blank large square represents 1 (as in the whole number 1)
The large squares with vertical lines have been divided into 10 equal parts. Therefore each strip = 1 ÷ 10 = 0.1
The large squares that have a grid of small squares have been divided into 100 squares. Therefore, each small square = 1 ÷ 100 = 0.01
Therefore, you need to color each accordingly.
- When coloring the strips, color from left to right.
- When coloring the small squares, color from left to right and top to bottom.
Once colored, you should then be able to compare the colored sections and decide which section is visually bigger, smaller (or equal)
1) 1.2 : color the entire large blank square to represent the "1", then color the first 2 strips in the adjacent square to represent the ".2"
1.13 : color the entire large blank square and 13 of the small squares.
1.2 > 1.13
2) 2.38 : color both large blank squares, then color 38 of the small squares
2.3 : color both large blank squares, then color 3 of the strips
2.38 > 2.3
3) 1.40 : color the large blank square, then color 40 of the small squares
1.4 : color the large blank square, then color 4 of the strips
1.40 = 1.4
