Answer:
5/9 and 6/11
= 5/9 × 11/11 and 6/11 × 9/9
= 55/99 and 54/99
= 55/99 > 54/99
<em>therefore, 5 by 9 is greater than 6 by 11</em>
So the since the length of the longer side is 45inches we know that the longer table is 5 times as larger than the small desktop. And we know 6 x 5 = 30.
So 45x30= 1,350 so the answer is 1,350 square inches! :)
Answer:
255
Step-by-step explanation:
total cost paid = fixed cost + total variable cost
total variable cost = distance travelled x variable cost per unit
two equations can be derived from the question
a + 10b = 105 equation 1
a + 15b = 155 equation 2
a = fixed cost
b = variable cost per unit
Subtract equation 1 from 2
5b = 50
b = 10
Substitute for b in equation 1
a + 10(10) = 105
a = 105 - 100 = 5
a = 5
cost of travelling a distance of 25km
5 + 10(25) = 255
Answer:
Type I error
Step-by-step explanation:
A type I error occurs if the null hypothesis is rejected when it is actually true.
Type I Type II
Reject null when true Fail to reject null when not true
Null hypothesis: ∪ = 30%
Alternative hypothesis: ∪ > 30%
The researchers concluded that more than 30% of first-grade students at this school have entered the concrete operational stage of development and they rejected the null hypothesis.
However, a census actually found that in the population of all first graders at this school, only 28% have entered the concrete operational stage.
A type I error has been made because in actuality the null hypothesis was true but was rejected.
Pie charts are used to illustrate data in proportions and percentages
The height of the bar for "Drama" is 70
<h3>How to determine the height of the bar</h3>
The number of results is given as:
n = 500
The pie chart is not given.
So, we solve this question using an assumed value for the proportion (p) of "Drama" movie genre
Assume that the proportion is 14%, then the height of the bar would be:
Height= 14% * 500
Multiply
Height= 70
Hence, the height of the bar for "Drama" is 70
