Answer:
18225
Step-by-step explanation:
let 7th term = t7
t7= a.3^(7-1) (common formula of geometric series is a.r^(n-1)
or, 25= a. 3^6
or, a=25/729
now, for 13th term,
t13= a.r^(13-1)
= 25/729 × 3^12
=18225

A farmer knows that a grocery store will reject a shipment of his vegetables if more than 4% of the vegetables contain blemishes. He inspects a large truckload of tomatoes to determine if the proportion with blemishes (p) exceeds 0.04. He selects an SRS of 150 tomatoes from the more than 2,000 tomatoes in the truck. Suppose that 8 tomatoes sampled are found to have blemishes. Which of the assumptions for inference about a proportion is violated, if any?
a. Large Counts: np > 10
b. Large Counts: n(1 – p) > 10
c. The sample is a random sample of the entire population.
d. 10% condition: the sample size is less than 10% of the population.
e. There do not appear to be any violations.
Answer:
Assumption A is violated
Step-by-step explanation:
x = number of blemishes = 8
n = sample size = 150
proportion = x/n = 8/150 = 0.0533
1. large counts: np> 10
= 150 * 0.0533 >10
= 7.995 > 10
this assumpton is obviously violated. 7.995 is not greater than 10
2. Large Counts: n(1 - p) > 10
150(1-0.0533)>10
150-7.995 > 10
142.005> 10
there is no violation. The assumption is satisfied
3. This assumption is satisfied. this is because the tomatoes were selected using simple random sampling.
4. 10% of the population = 0.1 * 2000 = 200
the sample size = 150
150 < 200
this assumption is satisfied
4. Triangle PSV is shown on the coordinate grid. The coordinates of each vertex of the triangle are integers. What is the slope of PV?
Answer:
-4,1
Step-by-step explanation:
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
If the coordinates of each of the vertex on the coordinate grid:
P = (2, 4)
S = (3, 4)
V = (3, 0)
The slope of PV is -4.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Triangle PSV:
The coordinates of each of the vertex on the coordinate grid:
P = (2, 4)
S = (3, 4)
V = (3, 0)
The slope of PV:
Choose any two coordinates from the line PV.
V = (3, 0) = (A, B)
P = (2, 4) = (C, D)
The slope of PV:
= (D - B) / (C - A)
= (4 - 0) / (2 - 3)
= 4 / -1
= -4
Thus,
If the coordinates of each of the vertex on the coordinate grid:
P = (2, 4)
S = (3, 4)
V = (3, 0)
The slope of PV is -4.

Two numbers are in the ratio 2:3 and have sum of 25...
What are the numbers?
Answer:
Use this as an example.
Step-by-step explanation:
a/b = 2/6 = 1/3
a/b = 1/3
b = 3a
a + b = a + 3a = 192
4a = 192
a = 192/4 = 48
b = 3a = 3(48) = 144

Answer:
x > 4
Step-by-step explanation:
Since it's an open circle, that means it has to be less than (<) or greater than (>)
Since it's going in the right direction, it means greater than (>)
The open circle starts at 4 so,
x > 4
x is greater than 4

Find the perimeter of the figure to the nearest hundredth. due today
Answer:
42.84 cm
Step-by-step explanation:
1) Find the perimeter of the top trapezoid. (In cm) 6 + 8 + 12 + 10 = 36 cm
2) Find the circumference of the semicircle with the formula 0.5(pie times D) where D is the diameter. Another formula is 0.5(pie times 2r) where r is the radius. Approximate pie to 3.14 so we should get 0.5 * 3.14 * 12 = 18.84 cm
3) We do not need the length of the base of the trapezoid so we take 36 + 18.84 - 12 = 42.84 cm

A line with a slope of 0 passes through the point (9,5). What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 5
Step-by-step explanation:
Any line with a slope of 0 is horizontal, represented by the equation y = a number. That number is the y-value of all the points the line intersects.
We know that that the line intersects (9,5). So, take the y-value of that point and write it into the equation of y = a number. Thus, the answer is y =5.
Point P is shown graphed on the coordinate grid as (6,4). In relation to point P, point A is located 2 units closer to the origin along the x-axis and 2 units farther from it along the y-axis. What would be the location of point A ?
Answer:
The coordinates of point A are [tex]A(x,y) = (4,6)[/tex].
Step-by-step explanation:
The location of point A is defined by the vectorial sum of absolute coordinates of point P and coordinates of point A relative to coordinates of point P, that is:
[tex]A(x,y) = P(x,y) + \vec v_{PA}[/tex] (1)
[tex]P(x,y)[/tex] - Absolute coordinates of point P.
[tex]A(x,y)[/tex] - Absolute coordinates of point A.
[tex]\vec v_{PA}[/tex] - Vector to point A relative to point P.
If we know that [tex]P(x,y) =(6,4)[/tex] and [tex]\vec v_{PA} = (-2, 2 )[/tex], then the absolute coordinates of point A are:
[tex]A(x,y) = (6,4) +(-2,2)[/tex]
[tex]A(x,y) = (4,6)[/tex]
The coordinates of point A are [tex]A(x,y) = (4,6)[/tex].

Martin says the area of a tile with a length of 1 foot by a width of 1 foot has an area of 1 square foot. And, to find 1/2 of this area, he would need to find 1/2 of the width and 1/2 of the length, and then multiply those two values. Unfortunately, his method is incorrect. Show at least one equation to show why this method would not work, and briefly state a method that will find 1/2 of 1 square foot.
