Ron jump is less than 10 feet. Ron jump is actually 5.45 feet.
How to find who jump more ?Stacey long jump was 10 feet. That is 5/6 foot longer than Ron's long jump.
Let's find if Ron jump more or less than 10 feet's.
Therefore,
Ron's Jump = x
Hence,
x + 5 / 6 x = 10
6x + 5x / 6 = 10
cross multiply
6x + 5x = 60
11x = 60
x = 60 / 11
x = 5.45
Therefore, Ron jump less than 10 feet.

Under a dilation, the point (2, 6) is moved to (6, 18). What is the scale factor of the dilation? enter your answer in the box.
Under a dilation, the point (2, 6) is moved to (6, 18). the scale factor of the dilation is 3
We know that if we transform point (x,y) by using dilation with scale factor k then the coordinate of the image will be (kx,ky).
Given: under a dilation, the point (2, 6) is moved to (6, 18)
Here (x,y)=(2,6) and (kx,ky)=(6,18)
x = 2
kx = 6
k = 6/x
k = 6/2
k = 3
Similarly taking y into account
y = 6
ky = 18
k = 18/y
k = 18/6
k = 3
Hence, Under a dilation, the point (2, 6) is moved to (6, 18). the scale factor of the dilation is 3

Confidence interval:
In statistics, a range around a measurement that conveys how precise the measurement is referred as confidence interval.
Given,
A precision instrument is guaranteed to read accurately to within 2 units. a sample of four instrument readings on the same object yielded the measurements 353, 351, 351, and 355. find a 90% confidence interval for the population variance.
Here we need to find the assumptions of the given situation,
From the given question we have identified the following,
Reading of instruments = 353, 351, 351, and 355.
Confidence interval = 90% = 0.09
Number of units = 2.
Based on these details, the standard deviation of this temple is 0.7.
So, the Z score is the same as the sample mean minus the population mean divided by the standard error, which is 2.857.

YZ ≅ AB
A translation is known as a rigid transformation. This is because it preserves congruence. Since CAB is created from XYZ, this tells us that:
X corresponds to C; Y corresponds to A; Z corresponds to B; XY corresponds to CA; YZ corresponds to AB; and XZ corresponds to CB.

a pharmaceutical company receives large shipments of ibuprofen tablets and uses an acceptance sampling plan. this plan randomly selects and tests 21 tablets, then accepts the whole batch if there is at most one that doesn't meet the required specifications. what is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects? (report answer as a decimal value accurate to four decimal places.) p(accept shipment)
0.9660 is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects
What is probability ?Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.
CalculationIf the number of tablets in a shipment is sufficiently large, we can consider the testing procedure you describe (selecting a random sample of 29 ibuprofen tablets and counting the number of defective tablets in the sample) to be a binomial probability experiment.
Let X = (Number of defective ibuprofen tablets in a random sample of 29 tablets.) Then we may reasonably assume that X follows a binomial distribution. For each "trial" (that is, each tablet selected), there are two possible outcomes, "success" (the tablet is defective), or "failure" (the tablet is not defective). Note that the word success as used in the binomial distribution does not carry the connotation of being a "good" outcome. A "success" is simply the outcome you are interested in counting, which in this case is the number of defectives in the sample. The important parameters for a binomial distribution are n (the number of trials) and p (the probability of success on any one trial.) For this situation, we have p = .01 (since we are told 1% of the tablets in the shipment are defective) and n = 29. The general formula for the binomial distribution is
P(x) = nCx·px·(1 - p)n-x
where x is the number of successes in n trials (In this problem, x is the number of defectives in a random sample of 29 tablets.) The symbol nCx is the "number of combinations of n things taken x at a time". This is the number ways of choosing x distinct objects from a set of n objects, without regard to order. It is given by
nCx = n!/[x!·(n-x)!]
where ! is the factorial symbol.
We want to find the probability that the shipment is accepted. We are told that a shipment will be accepted if at most one tablet doesn't meet the required specifications. That is, the number of defectives must be less than or equal to one.
P(Shipment accepted) = P(X ≤ 1). (In this case, X ≤ 1 if and only if X=0 or X=1)= P(0) + P(1).
So we calculate P(0) (the probability of 0 defective tablets in the shipment), and P(1) (the probability of 1 defective.) Using the formula for the binomial distribution, we have
P(0) = 29C0·(.01)0·(1 - .01)29 - 0.
But 29C0 = 1, so
P(0) = 1·(.01)0·(.99)29 ≅ .74717
Also,
P(1) = 29C1·(.01)1·(1 - .01)29 - 1.
Calculating 29C1, we have
29C1 = 29!/[1!·(29-1)!] = 29, so
P(1) = 29·(.01)1·(99)28
P(1) ≅ .21887
Finally, then, we have
P(Shipment accepted) ≅ .74717 + .21887 ≅ .9660 (to 4 decimal places.)

The image of the coordinates after a dilation of (9, −7) by a scale factor of 4 centered at the origin include the following: (36, -28).
What is dilation?In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
Next, we would have to dilate the coordinates of the preimage (9, -7) by using a scale factor of 4 centered at the origin as follows:
Coordinate A (9, -7) → Coordinate A' (9 × 4, -7 × 4) = Coordinate A' (36, -28).

The measure of the interior angle adjacent to the sixth exterior angle of the heaxagon is 118°.
What is an interior angle?Interior angles are those that lie inside a polygon.
To calculate an interior angle of a hexagon, we use the formula below.
Formula:
a = 360-(b+c+d+e+f)............ Equation 1Where:
a = The sixth exterior angleb = 55°c = 60°d = 69°e = 57°f = 57°Substitute these values into equation 1
a = 360-(55+60+69+57+57)a = 360-298a = 62°Recall that, the sum of an interior and exterior angle is 180°
a'+a = 180............... Equation 2Where:

The solutions to this system of linear equation 3x−2y=14 is ( [tex]\frac{2y + 14}{3}[/tex] , [tex]\frac{3x}{2}[/tex]-7).
Add 2y to both sides.
3x=14+2y
The equation is in standard form.
3x=2y+14
Divide both sides by 3.
[tex]\frac{3x}{3}[/tex] = [tex]\frac{2y + 14}{3}[/tex]
Dividing by 3 undoes the multiplication by 3.
x = [tex]\frac{2y + 14}{3}[/tex]
Now,
3x−2y=14
Subtract 3x from both sides.
−2y=14−3x
Divide both sides by −2.
[tex]\frac{-2y}{-2}[/tex] = [tex]\frac{14 - 3x}{-2}[/tex]
Dividing by −2 undoes the multiplication by −2.
