Well we know that
105° +z should equal 180° 
So 105° +z=180°
z=180° -105°
z=75°
Now we only need the y
All of the inside angles together should equal 360°
102° +83° +75° +y=360°
260° +y=360°
y=360° -260°
y=100°

Suzy randomly picks marbles form a bag containing 13 identical marbles. how many possible outcomes are there of she selects 10 m

allsm [11]

Answer:

286 possible outcomes.

Step-by-step explanation:

We have been given total 13 identical marbles

We need to select 10 out of 13

We will use combination:

$^nC_r=\frac{n!}{r!(n-r)!}$

here,n=13 and r=10 on substituting the values in the formula we get:

$^13C_{10}=\frac{13!}{10!(13-10)!}$

$^13C_{10}=\frac{13\cdot 12\cdot 11\cdot10!}{10!\cdot 3!}$

$\Rightarrow ^13C_{10}=\frac{13\cdot12\cdot11}{3\cdot2\cdot1}$

$\Rightarrow 286$

So, there are 286 possible outcomes.

Write the product using exponents -3/7×3/7×3/7

zlopas [31]

Answer:

$-(\frac{3}{7})^3$

Step-by-step explanation:

Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.

$-1 * (\frac{3}{7})^3$ = $-1 * \frac{3}{7} * \frac{3}{7} * \frac{3}{7}$
