What is R,S,W? I really need help!
Answer:
R- 73°
S- 73°
W- 138°
Step-by-step explanation:
Every triangle is 180°.
So 65+42=107
180-107=73
So that's the triangle to the right.
Now the other one is identical.
So we know the line w is on is 180°
On the corner w is on it took up 42°
So 180-42= 138° (which is 'w')

The ellipse is centered at the origin, its major axis is horizontal, with length 8; the length of its minor axis is 4;
Consider we need to find the equation of ellipse.
Given:
Ellipse is centered at the origin.
Major axis is horizontal, with length 8.
The length of its minor axis is 4.
To find:
The equation of ellipse.
Solution:
Major axis is horizontal, so standard form of ellipse is
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] ...(i)
where, (h,k) is center of the ellipse and length of major axis is 2a and length of minor axis is 2b.
Ellipse is centered at the origin. So, h=0 and k=0.
Major axis is horizontal, with length 8.
[tex]2a=8[/tex]
[tex]a=4[/tex]
The length of its minor axis is 4.
[tex]2b=4[/tex]
[tex]b=2[/tex]
Substitute h=0, k=0, a=4 and b=2 in equation (i).
[tex]\dfrac{(x-0)^2}{4^2}+\dfrac{(y-0)^2}{2^2}=1[/tex]
[tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex]
Therefore, the required equation of ellipse is [tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex].
Suppose a local manufacturing company claims their production line has a variance of less than 9.0. A quality control engineer decides to test this claim by sampling 35 parts. She finds that the standard deviation of the sample is 2.12. Is this enough evidence at the 1% level of significance, to accept the manufacturing companies claim? Calculate the appropriate test statistic (round to 2 decimal places as needed)
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to accept the manufacturing company claims
Step-by-step explanation:
From the question we are told that
The sample size is n = 35
The sample standard deviation is [tex]s = 2.12[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : \sigma ^2 = 9.0[/tex]
The alternative hypothesis is [tex]H_a : \sigma ^2 < 9.0[/tex]
Gnerally the test statistics is mathematically represented as
[tex]X^2 _{stat} = \frac{(n -1) * s^2 }{\sigma^2 }[/tex]
[tex]X^2 _{stat} = \frac{(35 -1) * 2.12^2 }{9 }[/tex]
=> [tex]X^2 _{stat} = 16.98[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n - 1[/tex]
=> [tex]df = 35 - 1[/tex]
=> [tex]df = 34[/tex]
From the chi - distribution table the critical value of [tex]\alpha[/tex] at a degree of freedom of [tex]df = 34[/tex] is
[tex]X^2_{\alpha, 34 } =56.060[/tex]
From the value obtained we see that the test statistics does not lie within the region of rejection (1.e 56.060 , [tex]\infty [/tex] )
Then
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to accept the manufacturing company claims
A box of Shredded Wheat weighs 0.35 kg and a box of Weetabix weighs 9/25 kg?
Which box is heavier?
Show your work
PLEASE HELP DUE TONIGHT THANK YOU SO MUCH
Answer: The box of Weetabix is heavier by 0.01 kg
Step-by-step explanation:
Divide 9/25 to get the decimal equivalent
9÷25 =0.36
Compare Shredded Wheat at 0.35 kg to Weetabix at 0.36 kg
Weight of the box of Shredded Wheat is [tex]0.35[/tex] kg and weight of the box of Weetabix is [tex]0.45[/tex] kg.
So, the box of Weetabix is heavier.
Weight of the box of Shredded Wheat [tex]= 0.35[/tex] kg.
Weight of the box of Weetabix [tex]= \frac{9}{25}[/tex] kg.
Here to compare the two weights, first make both of them similar.
Either make both of them decimals or both of them fraction.
Here, we will make both the weights decimals.
[tex]\frac{9}{20} = 0.45[/tex]
Now, [tex]0.45>0.35[/tex]
So, the box of Weetabix is heavier.

corey tracks heart rate after coming off the ice in a hockey game. in 1/6 minute, her heart beats 26 times.
Answer:156
Step-by-step explanation: 26÷1/6 =26×6 =156
The intensity level is moderate
In one second Corey's heart will beat 3 times.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Corey's heart beats 26 times in 1/6 minutes.
Assume that her heart beats [x] times in 1 second. Then -
1/6 of minute = 1/6 x 60 = 10 seconds
In 10 seconds, her heart beats 26 times
So, in one second, her heart will beat (26/10) = 2.6 times = 3 times (approx.).
Therefore, in one second Corey's heart will beat 3 times.

An AP is given by k,2k/3,k/3,0 .....Find the sixth term. find the nth term. If the 20th term is equal to 15, find k
9514 1404 393
Answer:
6th term: 8k/3n-th term: an = k + (k/3)(n -1)k = 45/22 for 20th term = 15Step-by-step explanation:
You know the general term of an AP is ...
an = a1 +d(n-1)
Here, a1 = k. The common difference is ...
2k/3 -k = -k/3
So, the general term is ...
an = k +(k/3)(n -1) . . . . the general term
__
The 6th term is then ...
a6 = k + (k/3)(6 -1) = (3k +5k)/3 = 8k/3 . . . . 6th term
__
The 20th term is ...
a20 = k + (k/3)(20 -1) = 22k/3
If this is 15, then the value of k is ...
22k/3 = 15
22k = 45
k = 45/22 . . . . value of k for a20 = 15
