Answer:
$560
Step-by-step explanation:
10% of $400 is $40. 40% of $400 is 10%x4. 40% of $400 is $160. Since her allowance increased by $160, it is now $560 per week.
$560 - if you `increase $400 by 40% the answer will be $560
An experiment consists of dealing 7 cards from a standard 52-card deck. What is the probability of being dealt exactly 4 face cards?
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

What is 8/9 + 1/6 as a fraction
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]

How do you Round 245.456 to the nearest hundredth ?
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

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.

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
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%.
Original domain and range:
D: [-1,1] R: [0,1]
What is the domain and range of
y= f(x+2)+1
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]

HELP. the staircase at the lighthouse tower has between 80 and 90 steps. if matt goes 2 steps at a time then 1 step is left at the end. If he goes 3 steps at a time then 2 steps are left. If he goes 4 steps at a time then 3 steps are left. How many steps are in the staircase?
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
