Answer:
50°
Step-by-step explanation:
The missing angle is an exterior angle
The formula says, that the sum of the two apposite adjacent angles inside the triangle equals two the exterior angle.
So 30° + 20° = 50°
The missing angle is 50°

A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19. What will be the predicted score for the dependent variable if the independent variable is 608.6?
Answer:
The predicted score for the dependent variable will be of 198,454.4.
Step-by-step explanation:
Equation of a regression line:
The equation of a regression line has the following format:
[tex]y = ax + b[/tex]
In which a is the slope and b is the intercept. x is the independent variable while y is the dependent variable.
A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19.
So [tex]y = 326.07x + 8.19[/tex]
What will be the predicted score for the dependent variable if the independent variable is 608.6?
y when x = 608.6. So
[tex]y = 326.07*608.6 + 8.19 = 198454.4[/tex]
The predicted score for the dependent variable will be of 198,454.4.

Fred lives way out in the country. He goes shopping only once a year. He bought 500 cans of corn at $0.30 each, 617 pounds of potatoes for $ 0.59 per pound, 379 boxes of Jell-O at $0.98 per box, 116 gallons of milk at $4.25 a gallon, and 2 loaves of bread costing $0.98 each. How much money did Fred spend?
Answer:
Hello there! Mizuki here to help!
The correct answer will be:
Fred is going to spend $1380.41
Step-by-step explanation:
The whole work I did:
500 x 0.3 = 150
617 x 0.59 = 364.03
379 x 0.98 = 371.42
116 x 4.25 = 493
2 x 0.98 = 1.96
150 + 364.03 + 371.42 + 493 + 1.96 = 1380.41

HELP PLEASE!!! (Angle) JNM = 103. Find (angle) JNK.
Answer:
Angles KNL and JNM are vertical angles so they are equal so
10y - 12 = 8y + 4
2y = 16
y = 8
So angle KNL = 10y - 12 = 10(8) - 12 = 80 - 12 = 68�
and, as a check
Angle JNM = 8y + 4 = 8(8) + 4 = 64 + 4 = 68�
Step-by-step explanation:
The value of ∠JNK will be equal to 47°.
It is given that the value of ∠JNM = 103°.
We have to find the value of ∠JNK using the diagram given.
What is an obtuse angle ?
The obtuse angle is an angle which is greater than 90° and less than 180° i.e., 120° is an obtuse angle.
As per the question ;
The value of ∠JNM = 103°
Let's find value of ∠JNK.
From the diagram ;
We can conclude that ;
∠JNK = ∠JNM - ∠MNL - ∠LNK
Here ;
∠JNM = 103°
∠MNL = 24°
∠LNK = 32°
So ;
∠JNK = ∠JNM - ∠MNL - ∠LNK
or
∠JNK = 103° - 24° - 32°
∠JNK = 103° - 56°
∠JNK = 47°
Thus , the value of ∠JNK will be equal to 47°.

after being discounted 40%, weather radio sells for $35.97. find the original price (round your answer to the nearest cent)
Answer:
$89.93
Step-by-step explanation:
Set up an equation:
Variable x = original price
40/100 = 35.97/x
Cross multiply
40 × x = 100 × 35.97
40x = 3597
Divide both sides by 40
x = 89.925
Round to the nearest cent:
5 rounds up so:
89.93
Check your work (use the original number instead of the rounded number to be more exact):
89.925 × 40%
Convert the percentage into a decimal to multiply:
89.925 × 0.40
35.97

What is the y- intercept of function f ?
A. -1
B. 1
C. -2
D. 5
Answer:
y intercept = 5
Step-by-step explanation:
f(x)=5•(1/6)^x
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)^0
= 5* 1 = 5
The y intercept is 5
If the question is
f(x)=5•(1/6)x
although I have never seen the question written this way
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)0
= 5* 0 = 0
The y intercept is 0
Answer:
B. 1
Step-by-step explanation:
The y-intercept occurs at x = 0
therefor the applicable function is
f(x) = -x + 1
at x=0
f(0) = -0 + 1
f(0) = 1

In order to control costs, a company wishes to study the amount of money its sales force spends entertaining clients. The following is a random sample of six entertainment expenses (dinner costs for four people) from expense reports submitted by members of the sales force. $157 $132 $109 $145 $125 $139 a. Calculate x , s2, and s for the expense data. In addition, show that the two different formulas for calculating s2 give the same result. b. Assuming that the distribution of entertainment expenses is approximately normally distributed, calculate estimates of tolerance intervals containing 68.26 percent, 95.44 percent, and 99.73 percent of all entertainment expenses by the sales force. c. If a member of the sales force submits an entertainment expense (dinner cost for four) of $190, should this expense be considered unusually high (and possibly worthy of investigation by the company)
Answer:
A) x¯ = 134.5
s² = 276.7 is the same for both formulas
s = 16.634
B) At 68.26%, we have (117.866, 151.134)
At 95.44%, we have (101.232, 167.768)
At 99.73%, we have (84.598, 184.402)
C) Yes, it will be considered high because 190 doesn't fall between any of the 3 tolerance intervals gotten in B above.
Step-by-step explanation:
A) The random 6 entertainment expenses are;
$157, $132, $109, $145, $125, $139
We want to find x¯ which is the mean.
Thus;
x¯ = (Σx)/n
x¯ = (157 + 132 + 109 + 145 + 125 + 139)/6
x¯ = 134.5
s² is the variance and can be calculated from 2 different formulas which are;
s² = (Σ(x - x¯)²)/n
Or s² = ((Σx²) - (Σx)²/n)/(n - 1)
For the first formula, when calculated we have;
s² = [(157−134.5)² + (132−134.5)² +(109−134.5)² + (145−134.5)² +(125−134.5)² + (139−134.5)²]/6
s² = 276.7
For the second formula;
(Σx²) = (157)² + (132)² + (109)² + (145)² +(125)² + (139)² = 109925
(Σx) = (157 + 132 + 109 + 145 + 125 + 139) = 807
Thus;
s² = (109925 - (807²/6))/(6 - 1)
s² = 276.7
So both formulas gave the same result of s²
s = √s² = √276.7
s = 16.634
B) from the empirical rule, 68% of the data will fall within one standard deviation while 95% of the data will fall within two standard deviations, and then 99.7% of the data will fall within three standard deviations from the mean.
Now, 68.26% will correspond to 1 standard deviation from the means and the tolerance level Formula here is;
x¯ ± s = 134.5 ± 16.634
This gives; (117.866, 151.134)
95.44% will correspond to within 2 standard deviations and the formula here is;
x¯ ± 2s = 134.5 ± 2(16.634)
>> (101.232, 167.768)
99.73% will correspond to within 3 standard deviations and the formula here is;
x¯ ± 3s = 134.5 ± 3(16.634)
>> (84.598, 184.402)
C) Yes it would be considered high because it doesn't fall between any of the 3 intervals in B above.

Answer:
The answer would be 7
Step-by-step explanation:
The equivalent value of the logarithmic equation is x = 7/3
What is Logarithm?The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
A = log ( 14/3 ) + log ( 11/5 ) - log ( 22/5 )
On simplifying , we get
From the properties of logarithm , we get
log A + log B = log AB
log A − log B = log A/B
So , A = log (14/3) + log (11/5) - log (22/5) = log [(14/3) × (11/5) / (22/5)]
A = log [(14/3) × (11/5) × (5/22)]
A = log ( 14/3 /2 )
A = log ( 7/3 )
Hence , the logarithmic equation is solved
