The perimeter of a rectangle is 304 cm. The length is 40 cm longer than the
width. Find the length and width. show steps pls
Answer:
p=2(L+W)
p=304
L=40+w
p=2(40+w+w) ,40+w is the value of L
304=2(40+2w)
304/2=2(40+2w)/2 divided both side by 2
152=40+2w
152-40=2w
112=2w
112/2=2w/2
w=56
and L =40+w
40+56=96.
so L=96 and W=56.
If YX=3x-4 and MO=9x-20, then MO=? {Diagram not necessarily drawn to scale.} *
Answer:
Step-by-step explanation:
I assume that XY is midsegment of a triangle, then MO = 2 XY
9x - 20 = 2( 3x - 4 )
9x - 20 = 6x - 8
3x = 12
x = 4
MO = 9(4) - 20 = 16 units

if a1=6 and an=2an-1 then find the value of a4
The value of A4 for the given condition if a1=6 and an=2an-1 is 48.
A1 = 6 means a(1) == 6
This is the first term of the sequence. Then you have the “rule” or the “closed form” of the sequence,
which is: an = 2an - 1 for n>1,
Should be written like this: a(n) == 2 × (an - 1) for n>1.
Now, It says that for any n>1, you should do this:
a(2) - that is the 2nd term is:
a(2) == 2 * (an - 1).
But (an -1) means “the term before this one”, which is the first term.
So, a(2) ==2 × 6 == 12, which is the 2nd term.
The 3rd term will be: a(3) == 2 × 12 = 24.
And the 4th term will be:
a(4) == 2 × 24 = 48.
So,the sequence will be:
6 , 12, 24, 48.
Thus, If a1=6 and an=2an-1, then the value of A4 under the indicated circumstance is 48.

Which of the following is a like term of -5.92?
Answer:
C. -7.78
Step-by-step explanation:
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. ...
Step 1: Find the Lowest Common Multiple (LCM) between the denominators. ...
Step 1: Convert all mixed numbers into improper fractions. ...
In this second method, we will break the mixed number into wholes and parts. ...
Thus, is equivalent to.

Fractions can be thought of as another way of seeing division. If you have one whole pizza and two people want to share it equally, they will divide it into two halves:
The bottom number of a fraction is the denominator. It tells how many parts a whole has been divided into. In this case our pizza is divided into two parts.
Proper Fractions, Improper Fractions, and Mixed Numbers
A proper fraction is one in which the numerator is smaller than the denominator.
An improper fraction is one in which the numerator is larger than the denominator. If the numerator is larger than the denominator, the fraction equals a number that is greater than one.

Finding the GCF (Greatest Common Factor)
The greatest common factor is the largest factor that divides two numbers. We find this by figuring out what prime numbers are multiplied together to make up each number. A prime number is a number that can only be divided by itself or by one. Examples of prime numbers are 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc. We want to focus on those that are less than ten in most cases.

Caitlin has a $10 gift certificate to the music
store. She has chosen a number of CDs from the $7
bargain bin. If the cost of the CDs is $32 after the gift
certificate is credited, how many CDs did Caitlin buy
9514 1404 393
Answer:
6
Step-by-step explanation:
Before application of the $10 credit, Caitlin's purchase was $32 +10 = $42. Your knowledge of multiplication facts tells you that 42 = 6×7. If each CD was $7, Caitlin bought 6 of them.
_____
If you need an equation, you could use ...
7x -10 = 32 . . . . the final value of Caitlin's purchase
7x = 42 . . . . . . . .add 10
x = 42/7 = 6 . . . . Caitlin bought 6 CDs.
A small lawnmower company produced 1,500 lawnmowers in 2008. In an effort to determine how maintenance-free these units were, the company decided to conduct a multiyear study of the 2008 lawnmowers. A sample of 200 owners of these lawnmowers was drawn randomly from company records and contacted. The owners were given an 800 number and asked to call the company when the first major repair was required for the lawnmowers. Owners who no longer used the lawnmower to cut their grass were disqualified. After many years, 183 of the owners had reported. The other 17 disqualified themselves. The average number of years until the first major repair was 3.3 for the 183 owners reporting. It is believed that the population standard deviation was 1.47 years. If the company wants to advertise an average number of years of repair-free lawn mowing for this lawnmower, what is the point estimate? Construct a 95% confidence interval for the average number of years until the first major repair.
Answer:
The 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).
Step-by-step explanation:
The (1 - α)% confidence interval for the average using the finite correction factor is:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}[/tex]
The information provided is:
[tex]N=1500\\n=183\\\sigma=1.47\\\bar x=3.3[/tex]
The critical value of z for 95% confidence level is,
z = 1.96
Compute the 95% confidence interval for the average number of years until the first major repair as follows:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}[/tex]
[tex]=3.3\pm 1.96\times\frac{1.47}{\sqrt{183}}\times\sqrt{\frac{1500-183}{1500-1}}\\\\=3.3\pm 0.19964\\\\=(3.10036, 3.49964)\\\\\approx (3.1, 3.5)[/tex]
Thus, the 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).
Find the product of the binomial (4x+3) with the trionomial (2x square -5x -3)
Answer:
The product of given binomial and trinomial is:
[tex]8x^3-34x^2-27x-9[/tex]
Step-by-step explanation:
A binomial is a polynomial with 2 terms and trinomial is a term with 3 terms.
Given
[tex](4x+3)\\and\\(2x^2-5x-3)[/tex]
Distributive property can be used to find the result.
Writing mathematically
[tex](4x+3)(2x^2-5x-3)\\= 4x(2x^2-5x-3)+3(2x^2-5x-3)\\= 8x^3-40x^2-12x+6x^2-15x-9[/tex]
Combining alike terms
[tex]= 8x^3-40x^2+6x^2-12x-15x-9\\= 8x^2-34x^2-27x-9[/tex]
Hence,
The product of given binomial and trinomial is:
[tex]8x^3-34x^2-27x-9[/tex]
A simple random sample of 64 observations was taken from a large population. The sample mean and the standard deviation were determined to be 320 and 120 respectively. The standard error of the mean is:________
a. 1.875
b. 40
c. 5
d. 15
e. None of the above
Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The sample size is n = 64
The mean is [tex]\= x = 320[/tex]
The standard deviation is [tex]\sigma = 120[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_x = \frac{\sigma}{ \sqrt{n} }[/tex]
=> [tex]\sigma_x = \frac{120}{ \sqrt{64} }[/tex]
=> [tex]\sigma_x =15[/tex]
