Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the numbe

r of nickels in the collection?

N+d=175, so d=175-n

0.05n+0.1d=13.30  now using d found above in this equation yields:

0.05n+0.1(175-n)=13.30

...

1.5(4-g)+1g=5.5

6-1.5g+g=5.5

6-0.5g=5.5

-0.5g=-0.5

g=1

5.5/4=1.375

So your grid should be:

3oz    1.50     4.50

1oz    1.00     1.00

4oz    1.375   5.50

Answer:

The equation we can use is 0.1(175-n)+0.05 n=13.30

Step-by-step explanation:

Number of Dimes= d

Number of Nickels= n

n+d=175, so d=175-n

The value of the dime is $0.10 and the value of each nickel is $0.05 and the whole  collection is worth $13.30, so

0.1 d+0.05 n=13.30

Replacing

0.1(175-n)+0.05 n=13.30 this is the equation we have to use to get the number of nickels.

How do you find the normal approximation without using the continuity correction?
Dennis_Churaev [7]
Let's say you want to compute the probability \mathbb P(a\le X\le b) where X converges in distribution to Y, and Y follows a normal distribution. The normal approximation (without the continuity correction) basically involves choosing Y such that its mean and variance are the same as those for X.

Example: If X is binomially distributed with n=100 and p=0.1, then X has mean np=10 and variance np(1-p)=9. So you can approximate a probability in terms of X with a probability in terms of Y:

\mathbb P(a\le X\le b)\approx\mathbb P(a\le Y\le b)=\mathbb P\left(\dfrac{a-10}3\le\dfrac{Y-10}3\le\dfrac{b-10}3\right)=\mathbb P(a^*\le Z\le b^*)

where Z follows the standard normal distribution.

If A = 3x power 2+2y + 2 and B=6x power 2 - 8y + 1 then A+B and A-B​
ollegr [7]

Answer:

see explanation

Step-by-step explanation:

Given A = 3x² + 2y + 2 and B = 6x² - 8y + 1 , then

A + B

= 3x² + 2y + 2 + 6x² - 8y + 1 ← collect like terms

= 9x² - 6y + 3

-------------------------------

A - B

= 3x² + 2y + 2 - (6x² - 8y + 1) ← distribute parenthesis by - 1

= 3x² + 2y + 2 - 6x² + 8y - 1 ← collect like terms

= - 3x² + 10y + 1
