To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds
Answer:
I think it increased by 0.05.
Step-by-step explanation:
If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0

Step-by-step explanation:
Your calculator or a spreadsheet can format the result of this division in scientific notation for you.
For the powers of 10, the applicable rule of exponents is ...
(10^a)/(10^b) = 10^(a-b)

If 4 cats enter a room and 3 leave how many monkey are in the water?
Answer:
1 monkey because it ate one of the cats
Step-by-step explanation:
Answer:
3 cats in 3corners
Step-by-step explanation:
the question is incorrect the correct question is IN A SQUARE ROOM THERE ARE 4 CATS IN EVERY CORNER?
Hey there !!!!
If you read that there are 4 cats in the room and in front of each cat is another 3 cats, then it might lead you to the answer of 16. This is not correct.
You will have reached this answer if you assumed that there was 3 cats in front of every cat in the corner. That would mean 4 cats in every coner.
You can reach this answer by dissecting each statement in the riddle. The first statement, “In a square room there are 4 cats in every corner of the room,” then we know that the room is square with 4 corners and that there are 4 cats to begin with.
The second statement of the riddle reads “In front of each cat there are 3 cats.” As we already know from the first statement that there are 4 cats in the room, each cat will see the other 3 cats in the other 3 corners of the room.
hope it helped
Show that the binomial is a factor of the polynomial. Then factor the polynomial completely.
g(x)=x3−x2−20x; x+4
g(x)=
Answer:
g(x) = x(x - 5)(x + 4)
Step-by-step explanation:
Here the binomial is x + 4, indicating that a root is -4. Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as
g(x) = x(x^2 - x - 20). Since -20 = -5*4,
g(x) = x(x - 5)(x + 4)
Answer:
x(x-5)(x+4)

Marissa is 7 years older than Mark. The sum of their ages is 59. How old are Marissa and Mark?
(A) First write an equation you can use to answer this question. Use x as your variable.
The equation is __________
Answer: Mark is ___________
and Marissa is ________
mark is 26=x and marissa id 33
if you take 59 take away 7 you get 52
then you wil devide 52 and get 26
you will use the 7 you took out earlier and add it to one of the 26 which will give you mark(26=x) and marissas(33) age .
A number is multiplied by 5,and then 3 is subtracted from the product.the result is 12.find the number
Solve the equation, enter the value in the box below.

Jaden is flying a kite and let’s off 275 feet of string. If the kite is 150 feet above ground and assuming the string is straight, what angle does the string make with the ground, to the nearest degree?
Answer:
≈ 33°
Step-by-step explanation:
So, first, you can draw a visual. Refer to the image attached below:
Using this info, you can use trigonometric ratios. Recall that:
tangent = opposite side/adjacent side
sine = opposite side/ hypotenuse
cosine = adjacent side/hypotenuse
You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.
So:
[tex]sinX = \frac{150}{275}[/tex]
However, we're not trying to find sinX, we're trying to find X.
So we would have to use inverse sine, which would then be:
[tex]X = sin-1 (\frac{150}{275} )[/tex]
Put this into your calculator, and:
X ≈ 33.05573115...

Answer:
You are given a right triangle. The sum of the two acute angles should add up to 90 degrees. Set up an equation using the expressions given and solve for x. Once you know the value of x plug it back into each expression to find the measure for each angle.
Step-by-step explanation:
Angle 1 + angle 2 = 90
solve for x = ____
Plug the value into each expression to find the measure of each angle.
Answer:
D
Step-by-step explanation:
(2x+6)+(5x+14)=90
7x+20=90
7x=70
x=10
(2x+6)=26°
(5x+14)=64°

Answer:
x=30° y=150°
Step-by-step explanation:
The inside angles of a triangle always add up to 180. So 65+85+x=180. x would equal 30. Next a line is always 180 degrees. So to two angles on the line must total to 180 degrees. We know x is 30 degrees, so y is the remaining angle. 30 + y = 180. y is 150.
Answer:
x=30° y=150°
