2. Hanna made 5 hit out of 13 during her first baseball game. What percentage of hits did she make?

MrRa [10]

Answer:

B. 38%

Explanation:

Given parameters:

Number of hits = 5hit

Total hits = 13

Unknown:

Percentage of hits shed made = ?

Solution;

The percentage of hit made = $\frac{number of hits }{Total hits}$ x 100

input the parameters and solve;

Percentage of hit made = $\frac{5}{13} x 100$

Percentage of hit = 38%

Percentage of hit = 38%

Use the Euclidean Algorithm to find the greatest common divisor of the polynomials f(x) = x^3 + 3x^2 + 6x + 1 and g(x) = 5x^4 +

fomenos

Answer:

3x+1.

Step-by-step explanation:

First we divide g(x)/f(x) (the process is in the first image):

5x-15 in Z7[x] is 5x-1 and $17x^2+86x+16$ is $r(x)= 3x^2+2x+2$ in Z7[x]. So

g(x)/f(x) = $(5x-1)(x^3+3x^2+6x+1)+3x^2+2x+2$

Now gcd(g,f) = gcm(f,r).

f(x)/r(x) = $5x(3x^2+2x+2) + 3x+1$

Then, gcd(f,r) = gcd(r,3x+1).

r/(3x+1) = $(x+5)(3x+1) +4$

Then, gcd(r, 3x+1) = gcd(3x+1,4) = 3x+1.

So, gcd(f,g) = 3x+1.

armand deposited $389.42 in a savings account that earns 3.2% simple interest. what is armand’s account balance after 7 years?

butalik [34]

Okay so since we have $389.42 to start with, we will multiply that by 3.2% which gives us roughly $12.46. Knowing that he will get an additional $12.46 per year, we multiply 12.46 by 7, giving us $87.22. Now, we just add 87.22 to 389.42, which is 476.64. Therefore, Armand has $476.64 as his account after 7 years.
