Answer:
30%
Step-by-step explanation:
In this question, we are to calculate the percentage of students who are female and do not play instruments.
We can first infer this from the table;
The number of females who do not play instruments = 64
The percentage of females who do not play instruments = number of females who do not play instruments/total number of students surveyed * 100%
That will be;
64/213 * 100% = 30.04 which is approximately 30%
Answer:
y = -0.4x - 3
Step-by-step explanation:
Using the slope formula, y2-y1/x2-x1 we need to find two points. Luckily, we already have two points, (5, -5) and (-5, -1). Plugging in, we have -4/10, or -0.4. Since now we know m = -0.4, we need to find the y-intercept. We have it as -3. Now we get y = -0.4x - 3 as our equation.
Answer:x=20/y
Step-by-step explanation:
x α 1/y
removing the constant of proportionality sign α and replace it with =k
x = k/y
x=10 y=2
10 = k/2
Cross multiply
10x2=k
20=k
k=20
Substitute k=20 in x=k/y
x=20/y.........required equation

opposite angles are equal
Answer:
7x+14=0, 7x=-14, x= -2
Step-by-step explanation:
add like terms, then get x on one side, number on the other, then divide both sides by 7
