The answer to column 4 is a circle pattern that is shifted one unit up. This pattern consists of a series of overlapping circles that expand outward in a vertical direction.
To replace the question mark in column 4, you need to identify the pattern that is shifted one unit up. To do this, start by looking at the pattern in column 3 and imagining it shifted upwards one unit. This will give you the pattern for column 4. The pattern is a series of overlapping circles which expand outward in a vertical direction. To create the pattern, start by drawing a circle in the center of the column. Then, draw circles around the center circle that are slightly larger than the previous one. Repeat this process until the circles reach the edge of the column. This will create the circle pattern that is shifted one unit up. Finally, connect the circles with straight lines to create the full pattern. This pattern will replace the question mark in column 4.

A bottle of liquid laundry detergent priced at $16.99 for a 52-load bottle has been changed to $16.49 for a 48-load bottle. By what percentage has the price per load changed?
Answer:
5.1% increase
Step-by-step explanation:
You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.
Percentage changeThe percentage change is given by the formula ...
((new price)/(old price) -1) × 100%
Price per loadThe price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.
old price per load = $16.99/52 ≈ $0.32673
new price per load = $16.49/48 ≈ $0.34354
ApplicationThen the percentage change is ...
(0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%
The price per load has increased by about 5.1%.

Assume that for dry rice and beans:
1 basin =20 cups
40 basins ≈ 1 sack
(a) A sack contains 100 kg of rice.
Estimate the number of kilograms of rice in 1 başin.
Estimate the number of grams of rice in 1 cup.
(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin.
Estimate the profit on a sack of rice.
(c) A trader charges #5 000 for a sack and 140 for a basin for beans.
Four women buy a sack of beans between them. They share the beans equally.
How many basins does each woman get?
How much does each woman save by buying the beans in this way?
(a) 1 sack of rice contains 100 kg of rice. If 1 basin of rice is equal to 20 cups, then 1 sack is equal to 40*20 = 800 cups.
Therefore, 1 basin of rice contains 100/40 = 2.5 kg of rice.
1 cup of rice contains 2.5/20 = 0.125 kg of rice.
(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin. If 1 sack contains 800 cups of rice, then the total revenue from a sack of rice is 800*200 = 160,000.
Therefore, the profit on a sack of rice is 160,000-6,000 = 154,000
(c) A trader charges #5 000 for a sack of beans and 140 for a basin. If four women buy a sack of beans between them, they share the beans equally, so each woman gets 1/4 of a sack of beans, which is equal to 1/440 = 10 basins of beans.
Each woman gets 10 basins of beans which cost 14010 = 1,400. If they had bought the beans individually at 140 per basin, they would have spent 140*10 = 1,400.
So each woman saves 5,000/4 = 1,250 by buying the beans in this way.

Answer: √6/8 x √6/18
Step-by-step explanation: The square root of A over B is the same as the squared of A, so it's important to know that before I start with this product. To go over the square.
I can do that if I combine the two square roots under the exact square root. This is only for multiplication.
I could take the square root of the term separately
Since I'm using fractions, I'll add the tops and bottoms to the equation.
The square root is eight times 18 and the squared root is six times six. It is the square to 36 over. It's eight times 18. There are 44 items.
The square to 36 is a question. I don't know what time it gives me. There were 36. 36 times six is 6. Six Over would be this. What time gives me 1 44?
Twelve times. 6/12 would be the day. It doesn't want me to reduce that, but I could.

The slope-intercept form of a line is y = mx + b, where m is the slope, and b is the y-intercept.
Shawn should use the point-slope formula ⇒ y - y₁ = m(x - x₁) and the y-intercept is -12.
We already know that the point-slope formula goes as such -
⇒ y - y₁ = m(x - x₁)
We have also been told that the slope of the line is 4 and the line passes through the point (1,-8). So, point (1,-8) = (x₁ , y₁) and the slope, m = 4.
Using the given values and the formula of point-slope, we get -
⇒ y - (-8) = 4(x - 1)
⇒ y + 8 = 4x - 4
⇒ 4x - y = -12
⇒ y = 4x - 12
This is the equation of the line.

A group of researchers establish a p-value of 0.05 for their hypothesis test. What does this mean?
a. The probability of getting a significant result for the test is 5%.
b. There is 5% probability that a true null hypothesis will be rejected.
C. The chi-square critical value for their dataset is 0.05
d. Only measured values of 0.05 or greater will be included in the test.
Answer:
b
Step-by-step explanation:
b. There is 5% probability that a true null hypothesis will be rejected.
A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

We have,
Right triangle ABC.
∠C = 90
The other two sides are a = 8 and b = 8
This means,
The angle opposite to the side a = 8 and b = 8 are equal.
Now,
∠A = ∠C
∠C + ∠A + ∠B = 180
90 + ∠A + ∠B = 180
2∠A = 180 - 90

The artist wants to paint a canvas that is proportional to the photograph, which measures 4 inches by 5 inches.
To calculate the proportionality, we will use the formula for converting inches to centimeters. 1 inch is equal to 2.54 centimeters. Therefore, 4 inches is equal to 10.16 centimeters and 5 inches is equal to 12.7 centimeters. Therefore, the artist should purchase canvases that are 10.16 centimeters by 12.7 centimeters in size. This will correspond to the following canvas prices: $6.43, $11.65, $18.47, and $22.80. By purchasing these canvases, the artist will ensure that the painting is proportional to the photograph.

A test plane files in a straight line with positive velocity v(t), v is a differentiable function of t.
selected value of v(t) for 0≤ t≤ 40are shown in the table.
We have to justify that what is that smallest number of instances at which the acceleration of plane could equal to zero on the interval (0,40).
We are aware about mean value theorem.
somewhere between t=0 , t=5, v'(t) =0
because v(t) is a differentiable function.
also, t=25 and t=30
v'(t)=0 because
[tex]\frac{v(30)-v(25)}{30-25} =0[/tex],
this means a(t) =0 for at least two value of t.
So, our function is differentiable in the interval 0 to 40, by mean value theorem a(t)=0 at least two value of t. it can be t=0 and t=5.

Here x = 5, The two angles are ∠B = 41° and ∠C= 63°.
What is a pentagon?A pentagon is a 2D polygon with five sides and five angles.
Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.
We are given in the figure , following information about a pentagon:
3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.
To solve for x, we need to add all of the angles together.
The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.
In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.
We can now solve for x by substituting our known values into the equation.
540 = 90 + (6x + 1) + (8x - 11)
540 = 14x
x = 540/14
x = 5
