If 10% of a number is 7, what is 80% of the number?
Zanzabum

Answer:


Step-by-step explanation:

Note that 80% is 8 times 10%.

Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8:  "80% of a number is 56."

Think:

10% of a number is 7,

20% is 14,

50% is 35,

70% is 49, and

80% is 56.

Total Sum of Square (SST) = 103.5

Regression Sum of Square (SSR) = 89.8

Erroe Sum of Square (SSE) = 13.7

The Coefficient of determination (R²) :

R² = SSR / SST

R² = 89.8 / 103.5

R² = 0.8676328

R² = 0.8676

Can somebody help me please !?
r-ruslan [8.4K]

Answer:

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = \frac{7\sqrt{3} }{x}

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.
