Answer:
Sue has a 12% chance of choosing a black dress and a gold necklace (as a fraction: 3/25, and as a decimal: 0.12).
Step-by-step explanation:
To find the probability of two separate events both occurring (in this case, selecting a black dress and a gold necklace), the probabilities are multiplied usually as fractions or decimals.
<u>As fractions:</u>
40% = 4/10
30% = 3/10
4/10 * 3/10 = 12/100 = 3/25, 0.12, or 12%
<u>As decimals:</u>
40% = 0.4
30% = 0.3
0.4 * 0.3 = 0.12 = 3/25, 0.12, or 12%
Answer:
8
Step-by-step explanation:
1 + 2(2*2) - 1
1 + 2(4) - 1
1 + 8 -1=8
Answer:
Step-by-step explanation:
we need to find the equation of the parabola with vertex (-5,3), with axis parallel to the x-axis.
general equation of horizontal parabola is
where (h,k) is the vertex
(-5,3) is the vertex. h=-5 and k=3. plug in the values in the general equation
Now find out the value of 'a' using x intercept (4,0)
Add 5 on both sides
a=1
the equation becomes
9514 1404 393
Answer:
x = 39
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +80² = 89²
x² = 89² -80² = 7921 -6400 = 1521
x = √1521
x = 39
