) Final averages are typically normally distributed with a mean of 72 and a standard deviation of 12.5. Your professor states th

Bad White [126]

Answer:

65.45

Step-by-step explanation:

Zscore = (x - mean) / standard deviation

x = score

Percentage below C :

D = 18% ; F = 12%

Sum = 30%

Obtain the Zscore for the proportion below D

P(Z < 0.30) = -0.524

Hence, Zscore = -0.524

Put Zscore = -0.524 in the equation :

-0.524 = (x - 72) / 12.5

-0.524 * 12.5 = x - 72

-6.55 = x - 72

-6.55 + 72 = x

x = 65.45

To receive a grade of C or better, score must be atleast 65.45

Find an input that yields an output of 214. rule: y= -15x+79

Dafna1 [17]

Answer:

The input have to be -9 to get output 214 with the rule y=-15x+79

Step-by-step explanation:

x is the input, y is the output so:

214 = -15x + 79

214 - 79 = -15x

15x = -135

x = -9

Find the greatest common divisor of 100 and 254, using • prime factorization- • euclidean algorithm-

larisa [96]

Via prime factorization:

$100=10^2=2^2\cdot5^2$
$254=2\cdot127$

of which the only common factor is a single power of 2, so $\mathrm{gcd}(100,254)=2$ .

Via the Euclidean algorithm:

$254=2\cdot100+54$
$100=1\cdot54+46$
$54=1\cdot46+8$
$46=5\cdot8+6$
$8=1\cdot6+2$
$6=3\cdot2+0$

which means $\mathrm{gcd}(100,254)=2$ , as expected.
