The probability that the average petal length will be between 1.3 and 1.6cm will be 0.5328.
How to calculate probability?From the complete question, x has an approximately normal distribution with a mean of 1.5cm and standard deviation of 0.2cm.
The associated probability for z values will be found in the normal distribution table and the probability will be subtracted. This will be:
= 0.6915 - 0.1587
= 0.5328
In conclusion, the probability that the average petal length will be between 1.3 and 1.6cm is 0.5328.

What is the sum of the first 11 terms in the arithmetic sequence if the first term is -3 and the common difference d is 5.
a.
152
b.
352
c.
402
d.
242
Answer:
d. 242..................
Answer:
d
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 5, thus
[tex]S_{11}[/tex] = [tex]\frac{11}{2}[/tex] [ (2 × - 3) + (10 × 5) ]
= 5.5(- 6 + 50)
= 5.5 × 44
= 242 → d
Given the arithmetic series: 2 + 4 + 6 +. Find the sum of T41 to T47
The series: 2 + 4 + 6 +.... is an arithmetic series
The sum of T41 to T47 is 616
How to determine the sum of the seriesThe series is given as:
2 + 4 + 6 +....
The above series is an arithmetic series with the following parameters:
Initial value, a = 2
Common difference, d = 2
Start by calculating S40 using the sum of n terms formula
[tex]S_n = \frac n2 * [2a + (n - 1)d][/tex]
So, we have:
[tex]S_{40} = \frac {40}2 * [2*2 + (40 - 1)*2][/tex]
[tex]S_{40} = 1640[/tex]
Calculate S47 using the same formula
[tex]S_{47} = \frac {47}2 * [2*2 + (47 - 1)*2][/tex]
[tex]S_{47} = 2256[/tex]
Subtract S40 from S47
[tex]S_{47} - S_{40} = 2256 - 1640[/tex]
[tex]S_{47} - S_{40} = 616[/tex]
Hence, the sum of T41 to T47 is 616

Daniel is currently 26 years older than his son. In six years he will be three times older
than his son. How old are both of them now?
Answer: sorr i onlyknow ti ar
Step-by-step:
Daniel is...remember "is" in a word problem means "equal"
So Daniel=x+26. x representing Daniel's son's age which we do not know.
In six years he will be three times his son's age, "times" meaning multiplication.
Daniel+6=3x, so just equate the two equations. So you must solve;
x+26=3x-6. From there I think you could handle things.

Write the equation in point-slope form of the line that passes through the points (4, 7) and (5, 1). Use the first point to write the equation.
Answer:
Step-by-step explanation:
Answer:
[tex]y-7=-6(x-1)[/tex]
Step-by-step explanation:
So first you need to find the slope of the line. You do this by doing [tex]m=\frac{y^{2}-y^{1}}{x^{1}-x^{2}}[/tex]. You would plug the points from the line into the equation to get [tex]m=\frac{1-7}{5-4}[/tex], and when you simplify you would get [tex]m=\frac{-6}{1}[/tex] or [tex]m=-6[/tex]. This means your slope is -6.
Now, point slope form is written as [tex]y-y^{1} = m(x-x^{1} )[/tex] so to write the equation you would plug in the slope and the first point to get [tex]y-7=-6(x-1)[/tex]
(CO 3) On the production line the company finds that 85.6% of products are made correctly. You are responsible for quality control and take batches of 30 products from the line and test them. What number of the 30 being incorrectly made would cause you to shut down production?
Answer and explanation:
There should be 85.6% correctly made products
If there is less than 85.6% correctly made products then production would be shut down
therefore 100-85.6= 14.4% of products can be incorrectly made and not more than that
In 30 batches 14.4% =0.144*30=4.32 products
Therefore there must not be more than 4.32 products incorrectly made in a batch of 30 else production is shut down

The two parallel lines will be b and d in the given question
What are parallel lines?From the figure, we can see that
Angles formed by lines b and a are 89. 5 degrees
Angles formed by lines c and a are 91.5 degrees
Angles formed by lines d and a are 89.5 degrees
Angles formed by lines e and a are 88.5 degrees
Angles formed by lines f and a are 90.5 degrees
Since the angle formed by line b with a and d with a are equal that is 89.5
so these two lines will never intersect each other
But other lines have varied angles then they can intersect at one point
Thus the two parallel lines will be b and d in the given question

17. The cost (in dollars) of making n birthday cakes is represented by
C = 24n + 35
How many birthday cakes are made when the cost is $395?
Answer:
the fist one = 160 - 24
the second one = 12.50 / 5
Step-by-step explanation:
Answer:
15. equation: g+24=160, and the answer is g=136
16. equation: 5d=12.50, answer is d=3.5 hours
17. 15 cakes are made when the cost is $395
Step-by-step explanation:
15: You know that there are 160 students in 7th grade. This would be on one side of the equal sign. You know that there are 24 more students in the 7th grade class than the 8th grade class. And we know that g represents the number of students in the 8th grade class. So you set up your equation as g+24=160. You would subtract 24 from both sides: g+24-24=160-24, which gives you g=136.
16: You spend $5 an hour, so, on one side, you will have 5. On the other you will have $12.50. We will let d represent dollars, and it will go with the 5 to give us 5d. The equation is 5d=12.50. From there, you will divide 5 from both sides: 5d/5=12.50/5, which gives you d=3.5.
17: So, we have the equation, and we just plug in what we know. So, $395=24n+35. From there, we will subtract 35 from both sides. That would give us $395=24n and we will divide 24 from both sides to give us n=15 cakes.
