Carlos and Clarita were asked to write y=2x2+4x-6 in factored form.
What do you think?
Answer:
2(x+3)(x-1)
Step-by-step explanation:
Because 2x^2+4x-6 can be divided by 2, you can divide them by two. This would make the equation 2(x^2+2x-3). To factor this, you have to find two equation that would make it true. The equation have to be _+_=2 and _x_=-3. The two blanks would be 3 and -1. 3+-1=2 and 3x-1=-3. This means that the equation is 2(x-1)(x+3).

#15: A shipment to a warehouse consists of 2,000 watchbands. The
manager chooses a random sample of 50 watchbands and finds that 2 are
defective. How many watchbands in the shipment are likely to be
defective?
watchbands
HELP
2 out of 50 are defective.
Divide 2 by 50: 2/50 = 0.04
Now multiply the total quantity by that:
2000 x 0.04 = 80
80 are likely to be defective.

How do you calculate
√25+√16-√49 in BODMAS
[tex] \sqrt{25} = 5 \\ \sqrt{16 } = 4 \\ \sqrt{49} = 7[/tex]
5+4-7 = 9-7 = 2
Our Answer 2
Answer:
The answer is 2
Step-by-step explanation:
√25 = 5
√16 = 4
√49 = 7
Now,
√25 + √16 - √49
5 + 4 - 7
9 - 7 = 2
Thus, The answer is 2

Answer:
area = 118.04 units²
Step-by-step explanation:
area of circle = πr² = (3.14159)(8²) = 201.06 units²
area of triangle:
corner angle - 60°/2 = 30°
sin 30° = m/8, m = 4
height of triangle = 4 + 8 = 12
cos 30° = n/8, n = 6.93, n = 1/2 base
base of triangle = 13.86
area of triangle = 1/2bh = 1/2(13.86)(12) = 83.02 units²
area of shaded portion = 201.06 - 83.02 = 118.04 units²

7 m
Surface Area = 90 m2
Surface Area = [? ] m2
Enter
Answer:
176.4
Step-by-step explanation:
1.) 7/5 = surface area/90 = (7/5)^2 = 49/25
2.) sa/90 = 49/25
3.) 4,410/25a
Surface area is 176.4

Find the area of the following colored regions?
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
[tex] \frac{1}{2} \times base \times height[/tex]
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
[tex] \frac{1}{2} \times 6 \times 6 = 18[/tex]
multiply this by 2
[tex]2 \times 18 = 36[/tex]
Now find the area of the whole circle
[tex]area = \pi {r}^{2} [/tex]
our radius is 6, therefore:
[tex]area = \pi {6}^{2} = 113.1[/tex]
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
[tex]113.1 - 36 = 77.1[/tex]
Answer:
Exact Area = 36pi - 36 square meters
Approximate Area = 77.04 square meters (when using pi = 3.14)
================================================
Explanation:
The circle has radius r = 6 meters. The area of the circle is...
A = pi*r^2
A = pi*6^2
A = 36pi
This is the exact area in terms of pi.
Because we have two right triangles, and each right triangle has the same leg length, we can effectively use the SAS theorem to prove the triangles are congruent. Therefore, both of the triangles shown have the same area. One triangle is a rotated copy of the other.
The area of one of the triangles is base*height/2 = 6*6/2 = 18 square meters. That means two of them combine to an area of 18*2 = 36 square meters.
Subtract this from the area of the circle to get the green shaded area
green area = (circle area) - (triangle areas)
green area = (36pi) - (36)
green area = 36pi - 36
This is the exact area in terms of pi. If you want the approximate area, then replace pi with its approximate value. Let's say we go for pi = 3.14
That means,
green area = 36pi - 36
green area = 36*3.14 - 36
green area = 77.04 square meters approximately
Use more decimal digits in pi to get a more accurate area value.
Suppose that whether it rains tomorrow depends on past weather conditions only through the last 2 days. Specifically, suppose that if it has rained yesterday and today, then it will rain tomorrow with probability .8; if it rained yesterday but not today, then it will rain tomorrow with probability .3; if it rained today but not yesterday, then it will rain tomorrow with probability .4; and if it has not rained either yesterday or today, then it will rain tomorrow with probability .2. Over the long term, what proportion of days does it rain
Answer:
The answer is "0.425".
Step-by-step explanation:
The T be a requirement today that such rains.
The Y be a situation yesterday that now it rained.
The O is a condition for tomorrow to rain.
[tex]P(O| (Y\ AND \ T)) = 0.8\\\\P(O|(Y \ AND \ NOT\ (T)) =0.3\\\\P( O|(NOT \ (Y)\ AND\ T)= 0.4\\\\P( O| NOT\ (Y) \ OR \ NOT \ (T)) =0.2[/tex]
There Arena and morrow overview To Aspects Which will rain:
[tex]Y\ AND \ T, Y \ AND \ NOT \ (T),\ NOT\ (Y) \ AND\ T, \ NOT(Y)\ OR \ NOT(T)[/tex]
Each has the option of [tex]\frac{1}{4}[/tex] INDEPENDENTLY happening.
Its possibility of tomorrow's rain is:
[tex]P(O) = P(O | Y\ AND\ T) P(Y\ AND\ T) + P(O|(Y \ AND \ NOT\ (T))[/tex]
[tex]P((Y\ AND \ NOT\ (T)) + P(O|(\ NOT\ (Y) \ AND \ T))P(\ NOT\ (Y) \ AND\ T) \\\\+ P( O| \ NOT\ (Y)\ OR\ NOT\ (T)) P(\ NOT\ (Y)\ OR\ NOT\ (T))\\\\[/tex]
[tex]=0.8\times \frac{1}{4} +0.3\times \frac{1}{4}+0.4\times \frac{1}{4}+0.2\times \frac{1}{4}\\\\ =\frac{1}{4}(0.8+0.3+0.4+0.2)\\\\= \frac{1.7}{4}\\\\= 0.425[/tex]

Step-by-step explanation:
A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you are equally likely to land in anyways what is the probability you were score more than five points
Answer:
[tex]Pr =0.75[/tex]
Step-by-step explanation:
Given
See attachment for wedge
Required
[tex]P(x > 5)[/tex]
The sample space of the wedge is:
[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(S) = 20[/tex]
The outcomes greater than 5 are:
[tex]x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(x>5) =15[/tex]
So, the probability is:
[tex]Pr =\frac{(n(x>5)}{n(S)}[/tex]
This gives:
[tex]Pr =\frac{15}{20}[/tex]
[tex]Pr =0.75[/tex]
