Answer:
I believe it is 47.
Step-by-step explanation: The reason why is because for a right angle it must be 90 degrees So, the way I solved this was getting 90-43 I got the 43 from BCD. then subtracted it and applied it to the other side, keep in mind I am only a freshman and it might be wrong super tiny chance but it might.

(a) Function formula of f(t) in terms of t is, f(t)=17-1.3t
(b) The domain of the function is 0 to 13.076.
(c) The range is 0 to 17
(d) 9.38 is the value exist for f(t)=4.8
(e) The correct option of this sub part is How many hours since the candle was lit when it is 4.8 inches long.
What is a Function?An input and an output are connected by a function. It functions similarly to a machine with an input and an output. Also, the input and output are somehow connected.
Solution of sub part (a)The initial length of the candle is 17 inch. It also given that, it burns with a constant rate of 1.3 inches per hour.
After one hour since the candle was lit, the length of the candle will be (17 – 1.3) = 15.7 inch.
After two hour, since the candle was lit, the length of the candle will be (15.7-1.3) = 14.4 inch.17 - 2(1.3) can be used to represent the candle's length after two hours.
Hence, the length of the candle after t hours when it was lit can be represented by the function, f(t)=17-1.3t
Solution of sub part (b)Putting f(t)=0 in the equation, we get
0=17-1.3t
-17=-1.3t
t=13.076
Hence, The domain of the function is 0 to 13.076
Solution of sub part (c)Putting t=0 in the equation, we get
f(t)=17-1.3t
f(t)=17-1.3×0
f(t)=17
Hence, The range is 0 to 17.
Solution of sub part (d)putting f(t)=4.8 in the equation we get
4.8=17-1.3t
4.8-17=-1.3t
t=9.38
Hence, the value of t for f(t) =4.8 is 9.38.
Solution of sub part (e)When the candle was 4.8 inches long, then time taken to lit from the equation is 9.38 hours.
Hence, The correct option of this sub question is How many hours since the candle was lit when it is 4.8 inches long.

Is (2, 3) a solution to this system of equations?
y = -2x + 7
y = x + 1
yes
no
Answers
For the point (2, 3), we have x = 2 and y = 3. Substituting these values into the first equation, we get:
y = -2x + 7
3 = -2(2) + 7
3 = 3
This equation is true, so the point (2, 3) satisfies the first equation.
Substituting x = 2 and y = 3 into the second equation, we get:
y = x + 1
3 = 2 + 1
3 = 3
This equation is also true, so the point (2, 3) satisfies the second equation.
Since the point (2, 3) satisfies both equations in the system, we can conclude that it is a solution to the system. Therefore, the answer is yes.
Answer:
Yes.
Step-by-step explanation:
(2, 3) means we'll let x be 2 and y be 3. Let's solve both equations first:
y = -2x + 7
3 = -2(2) + 7
3 = -4 + 7
:. 3 = 3
Okay, so one half is proven. Let's do the other half now.
y = x + 1
3 = 2 + 1
3 = 3

Based on the supply graph and the demand graph shown above, what is the price at the point of equilibrium?
Hint: Think about the point where they both meet. For example, if you were to place the graphs on top of each other, what would be the point of intersection?
Type the correct number below without the dollar sign.
Answers
Based on the supply graph and demand graph shown above, the price at the point of equilibrium is $ 30.
Demand refers to quantity of a commodity that the consumers are willing to, able to purchase at a given price during a given period of time. Supply refers to quantity of a commodity that the producers are willing to, able to offer for sale at a given price during a given period of time.
Demand curve slopes downward due to inverse relationship between price and quantity demanded whereas supply curve slopes upward due to direct relationship between quantity supplied and price. When both demand and supply curve intersect with each other balance is achieved. Intersection point between demand and supply curve is known as equilibrium.
At this point when prices are equal is known as equilibrium price and when quantiy demanded or supplied are equal it is known as equilibrium quantity. When we combine the given graph. Equilibrium is achieved at a point when price is equal to $ 30 and quantity is equal to 20 units.

PLS HELP! weights (in pounds) of catfish caught in the river: 4.8 3 2.7 4.4 4.8 9.9 What is the outlier? A) 3 lbs B) 4.8 lbs C) 9.9 lbs D) none
Answers
The correct answer is C) 9.9 lbs as it is above the upper boundary 6.4865, it is the outlier in this dataset.
What is an outlier?An outlier is an observation that is much higher or lower than the other observations in a dataset.
In this case, the weights of the catfish range from 2.7 to 4.8 lbs, with one observation that is much higher at 9.9 lbs.
Therefore, 9.9 lbs is the outlier in this dataset.
To find the outlier in this dataset, we can calculate the interquartile range (IQR).
This is done by first calculating the first quartile (Q1) and third quartile (Q3).
The Q1 for this dataset =3.75
and the Q3= 4.675.
IQR= Q3 - Q1
= 0.925.
We then calculate the lower boundary as Q1 - (1.5 x IQR) = 2.3625.
The upper boundary is Q3 + (1.5 x IQR)= 6.4865.
Since 9.9 lbs is above this upper boundary, it is the outlier in this dataset.

The equation that represent the given situation is y = 15x + 70
When she plants 3 stalks, each plant yields 115 ounces of beans
The first point = (3, 115)
When she plants 8 stalks, each plant yields 190 ounces of beans
The second point = (8, 190)
The slope of the line m = \(\frac{y_2-y_1}{x_2-x_1}\)
Substitute the values in the equation
The slope of the line m = (190-115) / (8-3)
= 75/5
= 15
The point slope form is
\(y-y_1=m(x-x_1)\)
Choose one point and substitute the values in the equation
y - 115 = 15(x - 3)
y - 115 = 15x - 45
y = 15x - 45 + 115
y = 15x + 70

What is the probability that the password does not have repeated letters, expressed to the nearest tenth of a percent?
Answers
We can see here that the probability that the password does not have repeated letters, expressed to the nearest tenth of a percent is = 9.8%.
What is probability?Probability is a measure of how likely an event is to happen. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.
The probability of an event can be calculated using the following formula:
Probability = Favorable Outcomes / Total Outcomes
The number of possible passwords is:
26 × 26 × 26 × 26 × 26 × 26 = 308,915,776.
The number of passwords with no repeated letters is
26P6 = 30,260,000.

a) How much is Darrell's annual contribution? b) How much is his semimonthly deduction?
Answers
Answer:The employer pays .90 * 12240 = $ 11016. The emplyee pays .10 *12240 = $ 1224 = annual contribution. Contribution rate = (100% - 90%) = 10%.
Step-by-step explanation:
Answer:
a) $1,224
b) $51
Step-by-step explanation:
a) To calculate Darrell's annual contribution, we need to determine the portion he pays out of the total premium.
Given that the employer pays 90% of the cost, Darrell is responsible for the remaining 10%.
Annual contribution = Total premium × 10%
= $12,240 × 0.10
= $1,224
Therefore, Darrell's annual contribution is $1,224.
b) To find Darrell's semimonthly deduction, we divide his annual contribution by the number of semimonthly periods in a year.
Number of semimonthly periods in a year = 12 (months) × 2 (semimonthly periods per month) = 24
Semimonthly deduction = Annual contribution / Number of semimonthly periods
= $1,224 / 24
= $51
Therefore, Darrell's semimonthly deduction is $51.

Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answers
Answer:
p value is 0.1343
Step-by-step explanation:
Null: u>= 442
Alternative: u < 442
Using the formula for z score:
(x - u)/sd/√n
Where x is 438, u = 442 sd can be determined from the variance = √variance =√576 = 24 and n = 44
z score = 438-442 / (24/√44)
z score = -4/(24/6.6332)
z = -4/3.6182
z =-1.1055
Now let's find the p value at 0.1 significance level using a z score of -1.1055, using a p value calculator, p value is 0.1343 which greatest than 0.1 meaning the day is not sufficient enough to conclude that the machine is underfilling the bags.
