Suppose that the hemoglobin levels among healthy females are normally distributed with a mean of 14 gdL. Research shows that exactly 95% of healthy females have a hemoglobin level below 15.9 gdL. What is the standard deviation of the distribution of hemoglobin levels in healthy females
Answers
Answer:
The variation in haemoglobin values in healthy human beings is relatively large; in women aged 18–49 years the mean haemoglobin concentration is 140 g/l while the value 2 standard deviations (SD) below the mean is 120 g/l, a difference of about 14%.
Sean has a box of pens. The box contains 6 blue pens, 8 black pens and 3 red pens. Some more blue pens are added to the box. The probability of selecting a blue pen is now ½. How many blue pens were added to the box?
Answers
Answer:
5
Step-by-step explanation:
Well, since the probability of blue pens is 1/2 you'll have to add the number of pens that is not blue. So that'll be 8+3 which equals 11. We currently have 6 blue pens and we need to add up the pens which will get 11. 11-6 equals 5, and that is the number of pens you will have to add.

find the quotient of [tex]\frac{(x^{3} - 2x^{2} + 6x + 3)}{ (x - 3)}[/tex] using long division
Answers
(x^3 - 2x^2 + 6x + 3)/(x-3)
= (x^3 - 3x^2 + (x^2 - 6x + 9)+ 12x - 6)/(x-3)
= (x^2(x-3) + (x-3)^2 + 6(2x - 1))/x-3
= x^2 + x - 3 + 6(2x - 1)/(x-3)
or
= x^2 + x - 3 remainder 12x - 6
or, in the form p(x) = q(x)d(x) + r(x):
(x^3 - 2x^2 + 6x + 3) = (x^2 + x - 3)(x - 3) + (12x - 6)
which implies that the quotient q(x) = (x^2 + x - 3) and remainder r(x) = 12x - 6

How do you Round 245.456 to the nearest hundredth ?
Answers
Answer:
245.46
Step-by-step explanation:
the hundredth point is represented by the "5" after the decimal, it goes like this
hundred, ten, one . tenth, hundredth, thousandth
2 4 5 . 4 5 6
so when you find the point you need to round to, if the number after it, is greater than five, the "hundredth" place goes up one
I hope this makes sense
2. 6 is above 5 so we round up to 245.46
3. Answer = 245.46
TIP: Rounding to the nearest hundredth is the same as rounding to two decimal places
Hope this helps!
An experiment consists of dealing 7 cards from a standard 52-card deck. What is the probability of being dealt exactly 4 face cards?
Answers
Answer:
The probability that the first card is a heart is 13/52
For the second card it is 12/51 (There are only 51 cards and only 12 of them are in the heart suit.)
For the third card it is 11/50
4th card 10/49
5th card 9/48
6th card 8/47
7th card 7/46
The total probability of all of these events occurring is the product of each individual probability.
So, the answer is (13 * 12 * 11 * 10 * 9 * 8 * 7) / (52 * 51 * 50 * 49 * 48 * 47 * 46)
which equals exactly 33 / 2,572,780 or roughly 1 chance in about 77,963

Answer all for brainliest asap pls
Answers
1.
Since ABCD is a rectangle, then
angleABE = 90 degrees
angle ABE + angle BEA + 41 = 180
Substitute the known and solve for angle BEA
angle BEA + 41 = 90
angle BEA = 49 degrees
But,
x + angleBEA + 61 = 180 (angles in a straight line)
x = 180 - 61 - 49
x = 70 degrees
2.
triangle XYZ is equilateral, meaning all angles in it are the same, each 60 degrees.
Therefore,
Angle YZX = 60
But Angle YZX = x + 32 (exterior angles equal to the sum of the two opposite interior angles)
60 = x + 32
Therefore,
x = 28 degrees
3.
Angle QPR = Angle QRP (equal oppo sides, equal opposite angles)
Therefore, 2angleQRP + 64 = 180 (angle sum of a triangle)
Angle QRP = 58 degrees
But angle QRP = x + 35 (exterior angles equal to the sum of the two opposite interior angles)
58 = x + 35
x = 23 degrees
Answer:
See below:
Step-by-step explanation:
For the first one, we know <ABC is 90 degrees due to it being a rectangle.
Since we know that, the angles in that triangle are 41 degrees 90 degrees and y degrees (y is <AEB) in this case.
We know that the sum of angles in a triangle are 180 degrees therefore:
If we solve that, we get that y is 49 degrees.
Now to get x, we know its a supplementary angle, therefore 61 degrees + 49 degrees + x = 180 degrees.
We now know that x is 70 degrees
For the second one, since its an equilateral triangle, we know that all angles inside of it are 60 degrees.
What we can do is first find what <XZW is by subtracting 60 from 180 due to the supplementary angles theorum.
Therefore <XZW is 120 degrees.
Now, all angles inside a triangle are always 180 degrees so therefore:
[tex]x=180-(120+32)\\x=28[/tex]
For the final one, we know that <QRP is equal to 64 degrees due to the bottom two triangles of an isoceles triangle being equal.
On that, we get 23 degrees for the last one due to supplementary angles + 180 deg in triangle.

You know that an exponent signifies repeated multiplication. The value of the exponent is the number of times the base appears as a factor.
You also know that identical factors in the numerator and denominator of a fraction cancel.
The given fraction has 9 factors of 4 in the numerator, and 2 factors of 4 in the denominator. The two in the denominator cancel an equal number in the numerator, leaving a value that has 7 factors of 4:

Original domain and range:
D: [-1,1] R: [0,1]
What is the domain and range of
y= f(x+2)+1
Answers
Step-by-step explanation:
if I understand correctly, then f(x) has the domain of [-1, 1] and the range of [0, 1].
the domain of a function is the interval or set of the valid values of x. and the range is the interval or set of the valid values of y.
the new function we could call g(x) is
y = f(x+2) + 1
so, remember, f(x) is only defined for x values of of [-1, 1].
the argument of f(x) must never be outside that interval, or it is undefined.
the new function now uses f(x) in the form of f(x+2). that means, if we use the same x values as for the original f(x) we would land mostly in undefined areas (only x=-1 would work), because we would use f(x) with argument values from 1 to 3.
how can we regulate this back to the valid interval of -1 to 1 ?
by saying that the domain of g(x) is actually 2 less than the domain of f(x) : [-3, -1]
the "+ 1" at the end changes the range. g(x) has then a range interval that is greater by 1 than the range interval of basic f(x).
so, it is [1, 2]

What is 8/9 + 1/6 as a fraction
Answers
Answer:
[tex]\frac{19}{18}[/tex] or [tex]1 \frac{1}{18}[/tex]
Step-by-step explanation:
First, both fractions need to have a common denominator.
The LCM of 9 and 6 is 18.
[tex]\frac{16}{18} +\frac{3}{18}[/tex]
Add the numerators.
You get: [tex]\frac{19}{18}[/tex]
The mixed number form is [tex]1 \frac{1}{18}[/tex]
The expression [tex]\frac{8}{9} +\frac{1}{6},[/tex] expressed as a fraction, is [tex]\frac{19}{18}.[/tex]
In order to add fractions, it is essential to determine a common denominator.
The common denominator is [tex]9 \times 6 = 54.[/tex]
Now, let's convert the fractions to have the common denominator:
When we multiply the fraction 8/9 with 6 in numerator and denominator we get 48/54.
[tex]\frac{8}{9}= \frac{8}{9} \times \frac {6}{6}[/tex]
[tex]= \frac{48}{54}[/tex]
Now multiply the fraction 1/6 with 9 in numerator and denominator to make 54 in denominator:
[tex]\frac{1}{6}= \frac{1}{6} \times \frac {9}{9}[/tex]
[tex]= \frac{9}{54}[/tex]
Now, we can add the fractions:
[tex]\frac{48}{54} + \frac{9}{54} = \frac{(48 + 9)}{54}[/tex]
[tex]=\frac{57}{54}[/tex]
Despite this, we have the option to simplify the fraction by dividing both the numerator and the denominator with their greatest common divisor, which is 3.
[tex]\frac{57}{54} = \frac{19}{18}[/tex]
Therefore, [tex]\frac{8}{9} +\frac{1}{6},[/tex] expressed as a fraction, is [tex]\frac{19}{18}.[/tex]

Answers
Answer:
90
Step-by-step explanation:
start from the beginning, then if you go 2 steps at a time, then you have 1 step left over at the end, let's assume the length of the stair case is x, so then we will be going up 2/3x steps, and have 1/3 x steps left.
2/3 x = somewhere between 80 and 90, so that means it must be divisible by 3, so 81,84,87,90
3/5 x ==> only 90

Not quite in proof format but here's a short explaination. You should be able to fill out the table yourself.
It is given that <T=<Y and <V+<U=180 degrees
<T=<Y are corresponding angles. Corresponding angles are congruent when the two lines (that the third line crosses to make a transversal) are parallel. So, l1 and l2 are parallel.
<V+<U are supplementary angles. They are same side interior angles. Same side interior angles are supplementary when two lines of the transversal are parallel (basically same thing as above, just different type of angle). So, l3 and l4 are parallel.
<R=<U because they are alternate interior angles. Alternate interior angles are congruent when the two lines are parallel (you have proved that l3 and l4 are parallel above).
<P=<C because they are alternate exterior angles. Alternate exterior angles are congruent when the two lines are parellel (you have proved that l1 and l2 are parallel above).
