Answer:
the problem is 1/7x+1/8?
I am a 2-digit number greater than 50. One of my
factors is 8 and I, myself, am a factor of 360. The
difference between my digits is 5.
What number am I?
Answer:72
Step-by-step explanation: greater than 50 ( 8x9=72 ) And 72 is a factor of 360, difference between my digits is 5 (72x5=360)

Answer:
Step-by-step explanation:
Last week Jovanna ran 30 miles more than Rachel. Jovanna ran
47 miles. How many miles did
Rachel run?
A. 30 + x = 47
B. 30 - x = 47
C. 47 + x = 30
D. 47x = 30
Answer: A
Step-by-step explanation:
if rachel is 'x' and jovanna ran 30 more miles than her, then jovanna ran 30+x miles
we know that jovanna ran 47 miles so we set both values equal to each other
30 + x = 47
which is option A :))
help please this is frinckin hard
Answer:
Hello! answer: r = 7
Step-by-step explanation:
Hi im sorry I will try to explain this the simplest way possible! so all of this will add up to 180 we know 1 angle is 55 and the 1 that isnt labelled is 90 because its a complementary angle leta add those and subtract so we can figure out what our last angle will have to equal so... 55 + 90 = 145
180 - 145 = 35 so now we know the last angle will have to equal 35 r is just a place holder its just representing something multiplied by 6 subtracted by 7 will equal 35 so...
6 × 7 = 42 and 42 - 7 = 35 So 7 is r!! Hope that helps!
Emergency rooms have reason to suspect that visits increase on the weekends. A recent report indicates that Monday through Thursday represent 10% per day of the weekly total visits while Friday accounts for 15%, Saturday 25% and Sunday 20%. If your ER has the following pattern, Monday, 120, Tuesday, 130, Wednesday 110, Thursday 95, Friday 160, Saturday 280 and Sunday 105. Does your facility have the same pattern as the recent report at the 10% level
Answer:
No the facility dose not have the same pattern as the recent report at the 10% level
Step-by-step explanation:
To determine if the Facility have the same pattern ; Perform Chi squared test for Goodness of fit
state the hypothesis
H0 : μ = same pattern
Ha : μ ≠ same pattern
expected frequency ( E ) = proportion * summation of frequency
summation of frequency = 1000
degree of freedom = 7 - 1 = 6
Next : Calculate the expected frequency (E) , (O-E)²/E. given that the observed frequency and expected proportion is given
For Monday
expected frequency = proportion * frequency = 0.1 * 1000 = 100
(O-E)²/E. = ( 120 - 100 )^2 / 100 = 4.0.
observed frequency ( O ) , expected frequency ( E )
For Tuesday
E = 0.1 * 1000 = 100
(O-E)²/E = ( 130 - 100 )^2 / 100 = 9.0
Repeat same calculations for Wednesday through Sunday
Then perform Chi-squared test
X² = Σ(O-E)²/E = 63.642
∝ = 0.1
df = 6
hence P-value = 0.000 ( =chisq.dist.rt(test-stat,df)
since P-value < ∝ ; we will fail to reject Ha hence we reject H0
how many odd integers are between −20/3 and 51/4
Answer:
-20/3 = -6.666
51/4 = 12.some
Odd integers between -6.66 to 12..
= -5,-3,-1,1,3,5,7,9,11
:)
The odd integers in between−20/3 and 51/4 are -5,-3,-1,1,3,5,7,9,11 so it is nine.
What is an integer?An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.
Integer ; ....-2 , -1 , 0 , 1 , 2 , .....
Integers are non-decimal numbers and all integers are rational numbers.
Given the two numbers,
−20/3 = -6.67
51/4 = 12.75
So integers in between −20/3 and 51/4 are ;
-5,-4,-3,-2,-1,1,2,3,4,5,6,7,8,9,10,11,12
Now odd integers out of them are;
-5,-3,-1,1,3,5,7,9,11
Hence "The odd integers in between−20/3 and 51/4 are -5,-3,-1,1,3,5,7,9,11 so it is nine".

Answer:
x=35 degrees
Step-by-step explanation:
Since the other side is 90 degrees you would have to add 55 degrees + 35 degrees in order to get 90 degrees for both sides.
Answer:
35°Step-by-step explanation:
its perpedicular so it adds up to 90°, therefore 90-55=x and x =35

Write an explicit formula an, the nth term of the sequence 27,-3,-33,-63
Answer:
The nth term is 27 - 30(n-1) or can be simplified to 57 - 30n.
Step-by-step explanation:
This is an arithmetic sequence (ie. each term equals the previous term with a constant value added (or subtracted from it)
T1 = 27
T2 = -3 = T1 - 30 = 27 - 30
T3 = -33 = T2 -30 = 27 -30 - 30=27-30X(2)
T4= -63 = T3 - 30 =27-30X(2)-30=27-30X(3)
In general, the nth term of this sequence:
S(n) = 27 - 30X(n-1)
Solve the following quadratic function by utilizing the square root method. y = 16 – 4x2
Answer:
we have
y=16-4x²
4x²=16

x=[tex]\sqrt{4}[/tex]
x=±2
Let's do
y=16-4x²Let y be 0
-4x²+16=0-4x²=-164x²=16x²=4x=±22. The two figures are similar. Consider Triangle 1 to be the pre-image and Triangle 2 to be the image. Write the similarity statement. Justify your answer by showing your work. (Hint: To justify your similarity statement, find the scale factor. What scale factor would you multiply the side lengths of Triangle 1 by to obtain the side lengths in Triangle 2)?

Two gamblers, call them Gambler A and Gambler B flip a coin repeatedly. The coin is unfair and comes up heads 2/3 of the time. Gambler A wins one dollar from Gambler B, when a head is tossed. Conversely Gambler B wins one dollar from Gambler A when a tail is tossed. The coin tosses are independent. The game ends when one of the gamblers runs out of money. There are 5 dollars in the pot. Determine the probability that Gambler A wins the game if he starts with I dollars. Here I
Answer:
≈ 0.52
Step-by-step explanation:
P( head ) = 2/3 , P( tail ) = 1/3
when a head is tossed ; Gambler A wins $1
when a tail is tossed : Gambler B wins $1
Determine the P( Gambler A wins the game ) if he starts with I dollars
Assuming I = $1
n = 5
p ( head ) = P( winning ) = 0.66
p( losing ) = 0.33
applying the conditional probability in Markov which is ;
Pₓ = pPₓ₊₁ + (1 - p) Pₓ₋₁
P( 1) = 0.66P₂ + 0.33P₀
resolving the above using with Markov probability
P( 1 ) = 0.51613
hence the probability of Gambler A winning the game if he starts with $1
≈ 0.52

please xplain and help with answers
Step-by-step explanation:
for mixed number to a improper fraction you take the whole number and times that by the denominator and add the numeriator
for example
[tex]8 \frac{3}{8} [/tex]
8 x 8 = 64
64 + 3 = 67
and after you get your last number (67) you put that over your original denominator which is 8 so it would be
[tex] \frac{67}{8} [/tex]
for the improper to mixed you see how many times you denominator goes into your numerator
another example is
[tex] \frac{13}{7} [/tex]
7 goes into 13 twice so your whole number is 2 and you have a remaining 1 so it would look like
[tex]2 \frac{1}{7} [/tex]
Answer:
A) 9/4
B) 67/8
C) 17/6
D) 9/2
E) 16/3
F) 127/12
G) 37/4
H) 41/6
Q) Whole Number: 1 Fraction: 6/7
R) Whole Number: 4 Fraction: 1/2
S) Whole Number: 1 Fraction: 8/9
T) Whole Number: 2 Fraction: 1/3
U) Whole Number: 2 Fraction: 3/7
V) Whole Number: 3 Fraction: 1/3
W) I am not 100% sure for this one but I think it's right.
Mixed Number - Whole Number: 1 Fraction: 5/8
Improper fraction - 13/8
Step-by-step explanation:
With improper fractions the first thing that you want to do is multiply the whole number with the denominator (the number on the bottom of the fraction), then add the numerator (the number on the top of the fraction). You also want to keep the denominator the same in both fractions.
When working with converting mixed fractions into improper fractions it is kind of the opposite, but it is a little harder to explain. Let's take letter Q as an example. If you know that you cannot divide the numerator and the denominator in anyway to make a whole number, the whole number will become a one and the numerator is how many are left. so in this case the answer for Q would be 1 6/7, 1 being the whole number and 6 from 6+7=13. now let's look at letter R, you know you can divide 2 four times into 9, the whole number will be 4 and the fraction will be 1/2, 4x2+1=9. You can also double check that you did it right by turning it back into a improper fraction from the mixed number state by multiplying the denominator with the whole number, then adding the numerator.
