Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
=90/1000=9/100=9%
Answer:
Solve the equation for y. This will put the equation into slope intercept form.
y = mx + b
where m is the slope and b is the y-intercept

Step-by-step explanation:
• I guess the question asks to find the value of w
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
• let's solve the equation using the quadratic formular
• Substitute following the mathematical operation rules:
• split the result:
Answer:
Correct answer is (e) all of the above.
step-by-step explanation:
As for the option (a) and (d), you can't give information you don't have. When you are not aware of the diseases, you can not give information about it.
For option (b), when the interviewer did not record the information or record it incorrect, it can not be used for survey.
For option (c), when correct questions are not asked, you can't required answers for the survey.
Summation of the above will be sources of error for the survey.
Answer:
37.5 degrees
Step-by-step explanation:
Congruent angles are the ones that are the same in value, in the attached image we can see the atom, the O atom forms 105 with both H atoms, if we use trigonometry we have
x+x+105=180
x=37.5 degrees the angle
