Answer:
Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.
Y= mx+b
Since this line is horizontal it's slope = 0 ==> the y=b
It passes by the point (3,-3) that means b=-3 & the equation is y=-3
<span> 2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17)
...........15x+6y=51</span>........equation 2
adding equation 1 and equation 2;
19x=57
x=3
2x-3y=3
(2*3)-3y=3
6-3=3y
y=1
Answer:
A. 6.2 X 10 ^-3
Step-by-step explanation:
First, you have to find the total weight by adding 0.0002 and 0.006 together, which gives you 0.0062. Then, follow basic setup of scientific notation by moving the decimal until one non-zero digit is to the left of the decimal, which brings the decimal to 6.2. Since you are moving the decimal right three places, the exponent is negative 3, making the notation 6.2 X 10 ^-3
Answer:
very less
Step-by-step explanation:
When rolling a fair 6 sided die 5 times there are 6^5 possible combinations.
Of those, there are 5 ways to roll exactly four sixes, and each of those ways have 5 possible results on the die which has not rolled a six, plus there is 1 way to roll five sixes. 5*5+1=26 combinations with at least four sixes.
Now, take the number of results which fit your conditions, divide by the number of possible results and you get your answer: 26/7776 which can be reduced to 13/3338, a bit less than 0.4%
