Answer:
C. 6
Step-by-step explanation:
It is given that the rectangles in the figure are similar.
<em>Thus, the corresponding sides of the two rectangles will be equal.</em>
So, we get,

i.e. 
i.e. 
i.e. 
i.e. x = 6.
Hence, the value of x is 6.
Answer:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
Step-by-step explanation:
For this case we are interesting in the parameter of the true proportion of people satisfied with the quality of education the students receive
The confidence level is given 95%, the significance level would be given by
and
. And the critical values are:
The estimated proportion of people satisfied with the quality of education the students receive is given by:

The confidence interval for the proportion if interest is given by the following formula:
And replacing the info given we got:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
Answer:
1/6561
Step-by-step explanation:
3^-2 = 1/9
1/9^4 = 1/6561
Answer:
a is <u>5</u><u>3</u><u>.</u><u>8</u><u>°</u><u>,</u> and b is <u>3</u><u>6</u><u>.</u><u>2</u><u>°</u>
Step-by-step explanation:
Using sine trig rule:


Summation of angles of triangle:

Measuring the figure with a ruler, length = 2 inch and width = 1.5 inch
It is given that 1/2 inch = 4 feet
1 inch = 4*2 = 8 feet
Area of rectangle = length * width
Length = 2*8 = 16 feet
Width = 1.5*8 = 12 feet
Area of Quintoe's bedroom = 16 feet * 12 feet = 
Hence option C is correct.
