Answer:
5√(7)m or 13.23m
Step-by-step explanation:
use pythagorean theorem
a²+b²=c²
c=20
b=15
a²+225=400
a²=175
√(175) = 5√(7) = 13.23
The height of the kite is 13.23 meters.
What is Pythagoras' theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A boy is flying a kite.
The length of the string is 20 meters and the horizontal distance between the boy and the kite is 15 meters.
Assuming there is no slack in the string,
then the height of the kite is,
= √(20)² - (15)²
= 13.23 feet.
Therefore, the height is 13.23 meters.

The triangle shown below has an area of 20 units squared. Find the missing side if the height is 8
Answer:
5 unitsStep-by-step explanation:
Lets keep the missing side as x
And we also know that the area of Triangle is,
[tex] \frac{1}{2} bh[/tex]
So taking this into consideration we can write a linear equation like this,
[tex] \frac{1}{2} bh = 20[/tex]
Where height is 8,
[tex] \frac{1}{2} \times b \times 8 = 20 \\ 4 \times b = 20 \\ b = \frac{20}{4} \\ b = 5[/tex]
So therefore the missing side is 5

Step-by-step explanation:
So, the little arow underneath lim that says x>1, this means that the qiuestion is asking:
What is the limit when x gets to 1?
We can use the quadratic they give us to solve this. Now, if you are doing this, you should know how to make a quadratic equation. So instead of making this long and tedious for you, I will use a graphing calculator.
So lets look at the graph below, specificly where x=1
as x reaches 1, what does the y coordinates look to be about? 3.
So we can conclude that the answer is that when x→1, y=3

A survey of 300 students from a New York State School District reveals that 112 favor year round school with two week vacations every ten weeks. Construct the 98% confidence interval for the true population proportion of all New York students who favor year round school.
Answer:
The 98% confidence interval for the true population proportion of all New York students who favor year round school is (0.3083, 0.4383).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A survey of 300 students from a New York State School District reveals that 112 favor year round school with two week vacations every ten weeks.
This means that [tex]n = 300, \pi = \frac{112}{300} = 0.3733[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3733 - 2.327\sqrt{\frac{0.3733*0.6267}{300}} = 0.3083[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3733 + 2.327\sqrt{\frac{0.3733*0.6267}{300}} = 0.4383[/tex]
The 98% confidence interval for the true population proportion of all New York students who favor year round school is (0.3083, 0.4383).
Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish to compare the means of two populations using paired observations. Suppose that d3.125, 2.911, and n8, and that you wish to test the hypothesis below at the 10% level of significance. What decision rule would you use? : 0 against : 0
Answer:

The critical region for one tailed test with 7 d.f is t > 1.415 for
H0 : ud ≤ 0 against the claim Ha: ud > 0
Step-by-step explanation:
The data given is
Population mean = ud= 0
Sample difference mean = d`= 3.125
Sample difference standard deviation = sd= 2.911
Sample size= n= 8
Formulate the null and alternate hypotheses as
H0 : ud ≤ 0 against the claim Ha: ud>0
The significance level ∝= 0.1
The degrees of freedom = n-1 = 8-1 = 7
The critical region for one tailed test with 7 d.f is t > 1.415
The test statistic is
t= d`- ud/ sd/ √n
Putting the values
t= 3.125-0 / 2.911/√8
t= 3.125/1.0292
t= 3.036
since the calculated value of t falls in the critical region we reject the null hypothesis .

What is asked?
What are given?
What operation to be used?
What is the number sentence?
What is the answer?
Answer:
area of rectangle = 110 cm^2
Step-by-step explanation:
here's your solution
=> length of rectangle = 35 cm. [ given ]
=> width of rectangle = 20 cm. [ given ]
=> we need to find area ,
=> area of rectangle = 2(length + width)
=> area of rectangle = 2(35 + 20)
=> area of rectangle = 2*55 =
=> area of rectangle = 110 cm^2

at x = 0
Answer: D
Step-by-step explanation:
only answer that makes sense. one at -2 is definitely an endpoint, one at 0 is infinite because you can’t see ends aren’t indicated.

A car company hires a marketing firm to advertise a particular model of car. After a year the marketing company presents the following graph to show the increase in sales resulting from their advertising campaign.
Answer:
Yes, the graph makes it appear as if sales increased three folds.
Step-by-step explanation:
The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.
Last year sale was about 137000 and it grew to 150000 as a result of advertisement.
But from the bar chart, it seems there was three times increase in sales.

Keisha, Boris, and Jose sent a total of 126 text messages over their cell phones during the weekend. Boris sent 4 times as many messages as Jose. Jose sent 6 fewer messages than Keisha. How many messages did they each send?
Answer:
Boris=504 keisha=120
Step-by-step explanation:
First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120

Using the graphing function on your calculator, what is the solution to the
system of equations show below?
Y+ 2x = 5
4y+ 5x=14
A. x=2 y=1
B. x= 1, y = 2
O C. More than 1 solution
O D. No solution
Answer:
x = 2 y = 1
Step-by-step explanation:
Given the system of equation
Y+ 2x = 5 ...1
4y+ 5x=14 ,,,,2
From 1;
y =5 - 2x ....3
Substitute 3 into 2
4(5-2x) + 5x = 14
20 - 8x + 5x = 14
20 - 3x = 14
-3x = 14-20
-3x = -6
x = 6/3
x = 2
Since y = 5-2x
y = 5-2(2)
y = 5-4
y = 1
Hence the required solution is (2,1)
