It’s weird. that’s what it is
Answer:
460 is part of the confidence interval, which means that we cannot say that there is significant evidence that the mean mathematics SAT score for entering freshmen class is greater than 460
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a pvalue of , so Z = 2.575.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 436 - 27.4 = 408.6.
The upper end of the interval is the sample mean added to M. So it is 436 + 27.4 = 463.4.
460 is part of the confidence interval, which means that we cannot say that there is significant evidence that the mean mathematics SAT score for entering freshmen class is greater than 460
Given the perimeter and length of the garden, the width of the garden was extended by 4 feet
<h3>How to find width of the garden</h3>
- Length of the garden = 12 feet
- Width of the garden = 7 feet
- Width extension =( 7 + w) feet
Perimeter = 2(length+ width)
46 = 2{12 + (7 + w)}
46 = 2(12 + 7 + w)
46 = 2(19 + w)
46 = 38 + 2w
46 - 38 = 2w
8 = 2w
w = 8/2
w = 4 feet

There will be 354087.24 mosquitoes on the 19th of May.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
.
Using the relation :
y = 180000(1.07)^x
x = Number of days since May 6 ;
y = Number of mosquitoes after x days
x = May 9 May 19 = 10 days
Therefore, a number of mosquitoes inhabiting the city on May 19 will be :
y = 180000(1.07)^10
y = 180000 x 1.96715136
y = 354087.24
y = 354087.24 (nearest whole number).
Therefore there will be 354087.24 mosquitoes on the 19th of May.
