Assume that the weights of ripe watermelons grown at a particular farm are normally distributed with a mean of 30 pounds and a standard deviation of 1.9 pounds. If the farm produces 400 watermelons, how many will weigh less than 27.87 pounds?
Answers
We know that,
[tex] \rightarrow \: z = \frac{x - \mu}{\sigma} \\ [/tex]
z = standard scorex = measuring valueμ = meanσ =standard derivationinserting the given values in the formula
[tex]\rightarrow \: z = \frac{27.87 - 30}{1.9} \\\rightarrow \: z = - 1.121[/tex]
Area that's left to z = -1.121
Area that's left to -1.121 = 0.1311
= 13.11%
Hence ,
13.11% of the watermelons weigh less than 27.87 pounds
To find the number of watermelons,
We'll find 13.11% of 400
= 13.11% x 400
= 13.11/100 x 400
= 52.44
hence , approx 52 watermelons would be lesser than 27.87 pounds

PLEASE HELP ME! If an arithmetic sequence has a4 = 107 and a8 = 191, what is a₁? (I need the steps too please).
Answers
Answer:
[tex]\displaystyle a_1 = 44[/tex]
Step-by-step explanation:
Recall the direct formula for an arithmetic sequence:
[tex]\displaystyle a_n = a_1 + d(n-1)[/tex]
Where d is the common difference.
Therefore, we can write the following two equations:
[tex]\displaystyle \left \{ {a_4 = 107 = a_1 + d(4-1)\atop {a_8 = 191 = a_1 + d(8-1)}} \right.[/tex]
Solve the system. Simplifying yields:
[tex]\displaystyle 107 = a_1 + 3d\text{ and } 191 = a_1 + 7d[/tex]
Subtracting the two equations into each other yields:
[tex]\displaystyle \begin{aligned} (191) - (107) & = (a_1 + 7d) - (a_1 + 3d) \\ \\ 84 & = 4d \\ \\ d & = 21 \end{aligned}[/tex]
Using either equation, solve for the initial term:
[tex]\displaystyle \begin{aligned} 107 & = a_1 + 3(21) \\ \\ a_1 & = 107-63 \\ \\ & = 44\end{aligned}[/tex]
In conclusion, the initial term is 44.
Answer:
[tex]\huge\boxed{\bf\:a_{1} = 44}[/tex]
Step-by-step explanation:
In the given arithmetic series,
[tex]a_{4} = 107[/tex][tex]a_{8} = 191[/tex][tex]a_{1} = ?[/tex]We know that,
[tex]\boxed{a_{n} = a + (n - 1)d}[/tex]
Therefore,
[tex]a_{4} = a + 3d = 107 -----(1)\\a_{8} = a + 7d = 191 -----(2)[/tex]
By solving the two equations (1) & (2)....
[tex]\:\:\:\:a + 7d = 191 \\-\underline{a + 3d = 107 }\\ \underline{\underline{\:\:\:\:\:\:\:\:\:\:\:\:\:4d = 84\:\:\:\:\:\:\:\:}}\\\\\\\\4d = 84\\d = 84 \div 4\\\boxed{d = 21}[/tex]
Now, we have the value of the common difference (d). To find [tex]a_{1}[/tex] or a, let's substitute the value of 'd' in (1).
[tex]a + 3d =107\\a + 3(21)=107\\a + 63 = 107\\a = 107 - 63\\\boxed{\bf\:a_{1} = 44}[/tex]

17) Find sine and cot
Answers
Answer:
79/156
Step-by-step explanation:
we know that cosx is the adjacent side over the hypotenuse.
hence, we can find the opposite side using the pythagorean theorem.
sqrt(13^2 - 5^2)
therefore, the opposite side is 12
opposite: 12
adjacent: 5
hypotenuse: 13
not that cot is adjacent over opposite while sin is opposite over hypotenuse.
So,
12/13 - 5/12
the answer is 79/156
Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).
A) (x,y) → (x-8, y)
B) (x,y) → (x, y - 8)
C) (x, y) → (x, y + 8)
D) (x,y) → (x+8, y)
Answers
Answer:
A) (x, y) → (x - 8, y)
Step-by-step explanation:
(3, 7) → (-5, 7)
Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.
A) (x, y) → (x - 8, y)
(3, 7) → (3 - 8, y)
(3, 7) → (-5, 7)
This matches our problem, and therefore, A is the correct answer.
Hope this helps!
Answer:
A) (x, y) → (x-8, y)
Explanation:
Present Point: (3, 7)
Future Point: (-5, 7)
The change be: (x, y)
Solve:
(3, 7) + (x, y) → (-5, 7)
change side
(x, y) → (-5, 7) - (3, 7)
simplify the following
(x, y) → (-8, 0)
Therefore, we identify this using (x - 8, y)

The amount of time a certain brand of light bulb lasts is normally distributed with a
mean of 1400 hours and a standard deviation of 50 hours. Using the empirical rule,
determine what interval of hours represents the lifespan of the middle 68% of light
bulbs.
Answers
The interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.
What is empirical rule?According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]
Here, we had where mean of distribution of X is \mu and standard deviation from mean of distribution of X is \sigma
The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1400 hours and a standard deviation of 50 hours. Thus,
[tex]\mu=1300\\\sigma=90[/tex]
Using the empirical rule, the interval of hours represents the lifespan of the middle 68% of light bulbs is,
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(1300- 90 < X < 1300+ 90) = 68\%\\P(1210 < X < 1390) = 68\%[/tex]
Thus, the interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.

2.7% of X equals 50,000. what is X?
don't give fake answers just for points YOU WILL BE REPORTED
Answers
Answer:
x = 1851851.851....
Step-by-step explanation:
Given statement:
2.7% of x equals 50,000.
When we convert the statement into an equation, we get;
⇒ 2.7% × x = 50,000
A percentage is always written as (Percent)/100 in fraction form. Thus;
⇒ 2.7/100 × x = 50,000
Using cross multiplication:
⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.
Divide both sides by 2.7
⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....Answer:
Percent in decimal form:
[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]
Therefore:
27% of X = 50000
[tex]\sf \implies 0.027 \cdot X=50000[/tex]
[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]
[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]
[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]
[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]
jack is a single-father of two children. he earns a net income of $3000 each month and is considering getting a second job to make end meet. his grocery shopping methods are erratic with random tips throughout the week. he typically spends $600 a month on food. what percent of his bet income is going toward food? should he consider budgeting more or less for groceries
Answers
Answer:20%
Step-by-step explanation:
Solution for 600 is what percent of 3000:
600:3000*100 =
( 600*100):3000 =
60000:3000 = 20
Now we have: 600 is what percent of 3000 = 20
Question: 600 is what percent of 3000?
Percentage solution with steps:
Step 1: We make the assumption that 3000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that $100%=3000.
Step 4: In the same vein, x%=600.
Step 5: This gives us a pair of simple equations:
$100%=3000(1).
x%=600(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / %=3000/600
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=600/3000
--->=20%
Therefore, $600 is $20% of $3000.

Answers
Based on the curve ; The graph is:
B. The curve is a many-to-one function.
Step-by-step explanation:Function--
A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.
Also, the graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to the y-axis should intersect the graph exactly once.
and one-to-one function--
A one-to-one function is such that no two elements have the same image i.e. any line passing through the co-domain and parallel to the x-axis should intersect the graph at most once.
The graph passes the vertical line test and hence is a function.Also, the graph of a linear function is a straight line.Hence, by looking at the graph we see that the graph is not a straight line.
Hence, it is not a linear function.
Also, it does not passes the horizontal line test (since somewhere in the interval (2,3) the same value is obtained many times )and hence it is not a one-to-one functionHence, the correct answer is:
