Determine whether the triangle is a right triangle 12, 10, 11...
Answer:
no it's not right angled
Step-by-step explanation:
thats because the left hand side is not equal to the right hand side
Answer:
You were on the right track: basically if a²+b²=c² is true , it's a right triangle...
a²+b²=c²
11²+10²=12²?
121+100=144?
221=144?
221≠144
Since they're not equal, the triangle isn't a right triangle.
Alma is estimating the proportion of students in her school district who, in the past month, read at least 1 book. From a random sample of 50 students, she found that 32 students read at least 1 book last month. Assuming all conditions for inference are met, which of the following defines a 90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month?
a. 32 + or - 1.645 underroot(32)(18)/50.
b. 32 + or - + 1.96 underroot(32)(18)/50.
c. 0.64 + or - 1.282 underroot(0.64)(0.36)/50.
d. 0.64 + or - 1.645 underroot(0.64)(0.36)/50.
e. 0.64 + or - 1.96 underroot(0.64)(0.36)/50.
Answer:
[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex], option D
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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
From a random sample of 50 students, she found that 32 students read at least 1 book last month.
This means that [tex]n = 50, \pi = \frac{32}{50} = 0.64[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
Confidence interval:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex]
So the correct answer is given by option D.

What is the slope of a line parallel to the line with equation 5x + 3y = 7?
−7/3
−5/3
−3/5
5/3
Answer:
so first we have to make it to y- intercept form
5x + 3y = 7
3y = 7 -5x since we moved to the other side of the equal sign it turns negative
now divide both sides by 3 becuase y needs to have no number in front of it
3y divided by 3
7 divided by 3
-5 divided by 3
now its y = 7/3 - 5/3x
now we need to reorder the terms so its y = mx + b
y = -5/3x + 7/3 or 2.3
mx equals slope so -5/3 is the slope
Step-by-step explanation:
Answer:
−5/3
Step-by-step explanation:
Parallel lines have the same slope. So to find the parallel line you must first find the slope of the original line. Do this by putting the equation into slope-intercept form. Once the equation is in the slope-intercept form it is, [tex]y=-\frac{5}{3}x+\frac{7}{3}[/tex]. Therefore, the correct answer is −5/3.

Divide both sides by 3
3(x+2)/3 = 15/3
You get x+2=5, subtract 2 from each side
x+2(-2)=5(-2)
x=3

You now have $4000. You will toss a fair coinup tofour times. Before each toss you can bet any amount of your money (including none) on the outcome of the toss. If heads comes up, you win the amount you bet. If tails comes up, you lose the amount you bet. Your goal is to reach $6000. It turns out that you can maximize your chance ofreaching$6000 by betting either the money you have on hand or $6000minus the money that you have on hand, whichever is smaller. Use simulation to estimate the probability that you will reach your goal with this betting strategywith the initial budget $4000.
Answer:
Since we want to bet the smaller amount, $6000 - budget, each time, we will be betting $2000 dollars each time. We know the odds of landing on heads with a coin is a %50 chance. Now if we get heads we can win. If we do not get heads we are left with $2000. Follow the betting equation again. $6000 - $2000 = $4000. We do not have $4000 so we will bet $2000. Once again we have a %50 chance of winning. If we win we will have $4000. If we loose, we will be left with nothing. If we were to loose, we would no longer be able to reach our goal because lack of money. Now lets say we won. We would have $4000 again so we would have to repeat like before. We would bet $2000 and if we win, we reach the goal. If we lost, we would also have to repeat steps before. This means the game could be over in 1 flip but could go on forever.
g A report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized and 20 out of 208 without pet dogs were burglarized. Suppose that this data is used to test the claim that the proportion of households with dogs that are burglarized is the same as the proportion of households without dogs that are burglarized. What would be the test statistic for this test
Answer:
Test statistic |Z| = 0.1040 < 1.96 at 0.05 level of significance
Step-by-step explanation:
Step(i):-
Given that a report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized
First proportion
[tex]p_{1} = \frac{x_{1} }{n_{1} } = \frac{10}{108} = 0.0925[/tex]
Given that a report on the nightly news broadcast stated that 20 out of 208 households without pet dogs were burglarized
Second proportion
[tex]p_{2} = \frac{x_{2} }{n_{2} } = \frac{20}{208} = 0.0961[/tex]
where
[tex]P = \frac{n_{1}p_{1} +n_{2}p_{2} }{n_{1} +n_{2} }[/tex]
P = 0.09486
Q = 1 - P = 1 - 0.09486 = 0.90514
Step(ii):-
Test statistic
[tex]Z = \frac{p_{1}-p_{2} }{\sqrt{PQ(\frac{1}{n_{1} } +\frac{1}{n_{2} } )} }[/tex]
[tex]Z = \frac{0.0925-0.0961 }{\sqrt{0.09486 X 0.90514(\frac{1}{108 } +\frac{1}{208 } )} }[/tex]
Z = -0.1040
|Z| = |-0.1040|
|Z| = 0.1040
Critical value Z = 1.96 at 0.05 level of significance

A machinist creates a spacer by drilling a 3 cm diameter hole through the middle of a cylinder that has a diameter of 5 cm and a height of 0.5 cm. What is the volume of the finished spacer to the nearest tenth cm3?
A. 1.6 cm^3
B. 6.3 cm^3
C. 12.6 cm^3
D. 19.7 cm^3
No dam links
Answer:
Step-by-step explanation:
Find the difference of the volume of outer cylinder and volume of inner cylinder.
Outer cylinder:
diameter = 5 cm
r = 5/2 = 2.5 cm
h = 0.5 cm
Volume = πr²h
= 3.14 * 2.5 *2.5 * 0.5
= 9.8125 cm³
Inner cylinder:
diameter = 3 cm
r = 3/2 = 1.5 cm
h = 0.5 cm
Volume = 3.14 * 1.5 *1.5 *0.5
= 3.5325 cm³
Volume of the finished space = 9.8125 - 3.5325
= 6.28
= 6.3 cm³
Answer:
6.3 cm³
Step-by-step explanation:

Triangle ABC has vertices A(-4,-1), B(-3,-5), C(-1, -1). Graph and label the vertices of ABC
and its image A'B'C' after translating it to 4 units right and 3 units up. Choose the correct
ordered pairs of the image A'B'C'.
(2 Points)
O A'(4.1), B (3,5), C' (1.1)
O A'(0,2), B(1, -2). C'(3.2)
O A'(0.2), B (1,2), C'(-3,-2)
Answer:
A'(0,2), B(1, -2). C'(3,2)
Step-by-step explanation:
Given
[tex]A = (-4,-1)[/tex]
[tex]B = (-3,-5)[/tex]
[tex]C =(-1,-1)[/tex]
Solving (a); Graph and Label ABC
See attachment for graph
Solving (b): Graph and Label A'B'C'
Translation:
4 units right
3 units up
4 units right
The rule is:
[tex](x,y) \to (x + 4,y)[/tex]
So, we have:
[tex]A = (-4,-1)[/tex] ==> [tex](-4+4,-1) =(0,-1)[/tex]
[tex]B = (-3,-5)[/tex] ==> [tex](-3+4,-5) =(1,-5)[/tex]
[tex]C =(-1,-1)[/tex] ==> [tex](-1+4,-1) =(3,-1)[/tex]
3 units up
The rule is:
[tex](x,y) \to (x,y+3)[/tex]
So, we have:
[tex](0,-1)[/tex] ==> [tex]A' =(0,-1+3) = (0,2)[/tex]
[tex](1,-5)[/tex] ==> [tex]B' =(1,-5+3) = (1,-2)[/tex]
[tex](3,-1)[/tex] ==> [tex]C' =(3,-1+3) = (3,2)[/tex]
The coordinates of A' B' and C' are:
A'(0,2), B(1, -2). C'(3,2)

Johnny wants to invest $10,000 at 4.5% interest rate compounded quarterly, How much will he have after 38 years?
Answer:
a= $54764.26
Step-by-step explanation:
r=R/100
r=4.5/100
r=0.045 rate per year
A = P(1 + r/n)nt
A = 10,000.00(1 + 0.045/4)(4)(38)
A = 10,000.00(1 + 0.01125)(152)
A = $54,764.26

Find the length of chord AD
9514 1404 393
Answer:
AD = 15
Step-by-step explanation:
The products of the segment lengths are the same.
(x -2)(x +7) = 4(2x -1)
x^2 +5x -14 = 8x -4
x^2 -3x -10 = 0
(x -5)(x +2) = 0
The positive solution is x=5.
Chord AD is ...
(x -2) +(x +7) = 2x +5 = 2(5) +5 = 15
Chord AD is 15 units long.
