Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%

Read the following two statements. Then, if possible, use the Law of Detachment to draw a conclusion. If Robbie wants to save money to buy a car, he must get a part-time job. Robbie started a new job yesterday at a grocery store. Robbie wants to save money. Robbie wants to buy a car. not possible If Robbie wants to save money, he must get a part-time job.
Final answer:
Using the Law of Detachment, we can conclude that Robbie wants to save money because he started a new job and the first condition states that he needs a job to save for a car.
Explanation:
Using the Law of Detachment, we can draw a conclusion from the following two statements:
If Robbie wants to save money to buy a car, he must get a part-time job.Robbie started a new job yesterday at a grocery store.Since Robbie started a new job, which is assumed to be part-time, we can conclude that Robbie wants to save money, as per the first statement which sets up a condition that needs to be fulfilled in order to save money. The specific intention of buying a car is not directly established, but it's often implied that people save for larger investments or expenses. The Law of Detachment only allows us to conclude propositions that directly follow from the given condition. Therefore, the direct conclusion we can draw here, based on the given statements and the Law of Detachment, is that Robbie wants to save money.
Final answer:
According to the Law of Detachment, Robbie wants to buy a car since he wants to save money and he has started a new job.
Explanation:
The Law of Detachment states that if we have a conditional statement of the form "If p, then q", and we know that p is true, then we can conclude that q is also true. In this case, let's analyze the given statements:
1. If Robbie wants to save money to buy a car, he must get a part-time job.
2. Robbie started a new job yesterday at a grocery store.
From statement 1, we can see that Robbie wanting to save money is the condition (p), and getting a part-time job is the conclusion (q). Since statement 2 confirms that Robbie has started a new job, which satisfies the condition (p), we can use the Law of Detachment to conclude that Robbie wants to save money (q) and therefore Robbie wants to buy a car (q). So, the conclusion is: that Robbie wants to buy a car.
△VAT≅△BDT. What is length of BT?
Enter your answer in the box.
we know that
If △VAT≅△BDT, then the corresponding sides will be congruent
[tex]VT=BT\\VA=BD\\ AT=DT[/tex]
we have
[tex]VT=6.3\ unit\\VA=3.7\ unit\\AT=4.7\ unit[/tex]
so
[tex]BT=6.3\ unit[/tex]
therefore
the answer is
[tex]BT=6.3\ unit[/tex]

What does it mean for data on a scatter plot to have no association? How does that affect the line of best fit?
Answer:

An oil slick is expanding as a circle. The radius of the circle is increasing at the rate of 20 meters per day. Express the area of the circle as a function of d, the number of days elapsed.
Answer:
Step-by-step explanation:
d = number of days since the oil slick started
r = radius in d days = 22d
A(d) = area of oil slick in d days = π(22d)2
A(d) = 484πd2
A parabola opens to the left. Which could be the equation of the parabola?
(x – 4)2 = 4(y + 3)
(x – 4)2 = –4(y + 3)
(y – 4)2 = 4(x + 3)
(y – 4)2 = –4(x + 3)
Answer:
[tex](y - 4)^2 = -4(x + 3)[/tex]
Step-by-step explanation:
When parabola opens the left then it is a horizontal parabola
Vertex form of horizontal parabola is
[tex](y-k)^2= 4p(x-h)[/tex]
where (h,k) is the vertex
When the parabola opens to the right then 4p is positive
when parabola opens to the left then 4p is negative
Now we look at the given equation and check with vertex form of parabola
[tex](y - 4)^2 = -4(x + 3)[/tex]
Here the value of 4p is negative , so parabola opens left
solve for p if 2|p|=4

What is the inverse of f(x)=x4+7 for x≥0 where function g is the inverse of function f?

g(x)=x√4−7 , x≥0
The points on the inverse function are (9, -3), (1, -1), (0, 0), and (4, 2). The inverse of f(x)=4x+3 is[tex]f^{-1}(x) = -3 + \frac{1}{4}x[/tex]. The inverse of g(x)=−4/3x+2 is [tex]g^{-1}(x) = \frac{3}{4}x + \frac{2}{3}[/tex] . The inverse of f(x)=x^4+7 for x≥0 is [tex]g(x) = \sqrt{\frac{x-7}{4}}[/tex], for x≥7.
Explanation:To find the points on the graph of the inverse of the function, simply switch the x and y coordinates. So, the points on the graph of the inverse function would be (9, -3), (1, -1), (0, 0), and (4, 2).
For the inverse of the function f(x)=4x+3, you rearrange the equation to solve for x. That gives [tex]f^{-1}(x) = -3 + \frac{1}{4}x[/tex]Therefore, the correct answer is [tex]f^{-1}(x) = \frac{1}{4}x - \frac{3}{4}[/tex]
The inverse of the function g(x)=−4/3x+2 could be found in the same way, which gives[tex]g^{-1}(x) = \frac{3}{4}x + \frac{2}{3}[/tex]
As for the question regarding invertible functions, without the images it is not possible to provide an answer.
The inverse of the function [tex]f(x)=x^4+7[/tex] for x≥0 is calculated by swapping x and y, and then solving for y. This yields: [tex]g(x) = \sqrt{\frac{x-7}{4}}[/tex], for x≥7.
