In a survey of 10 musicians, 2 were found to be left-handed. Is it practical to construct the
90% confidence interval for the population proportion, p?
Answer:
-0.0081<p<0.4081
Step-by-step explanation:
Using the formula for calculating the confidence interval expressed as;
CI = p±z√p(1-p)/n
p is the proportion = x/n
n is the sample size
x is the amount that are left-handed
p = 2/10
p = 0.2
z is the z score at 90% CI = 1.645
Substitute the values into the formula;
CI = 0.2±1.645√0.2(1-0.2)/10
CI = 0.2±1.645√0.2(0.8)/10
CI = 0.2±1.645√0.16/10
CI = 0.2±1.645√0.016
CI = 0.2±(1.645*0.1264)
CI = 0.2±0.2081
CI = (0.2-0.2081, 0.2+0.2081)
CI = (-0.0081, 0.4081)
hence the 90% confidence interval for the population proportion, p is expressed as -0.0081<p<0.4081

MS. Candos has 90 invitations to hand out. she will hand out 42 of them the rest will be handed out by 6 students how many got handed out an equal number if invitations
Help i will give brainliest to the first one to have a REAL answer
Answer:
y = -32
Step-by-step explanation:
-6 (y+15) = -3y + 6
-6y - 90 = -3y + 6
-3y - 90 = 6 + 90
= -3 = 96
y = -32
Answer:
Y=28
Step-by-step explanation:
Distribute-6(y+15) > -6y-90
-6y-90=-3y+6 add the -3y to the -6y and the -90 to the 6
-3y=-84
Then just divide -84 by -3

Expand the brackets.
[tex]\frac{3}{2}[/tex] × 10y + [tex]\frac{3}{2}[/tex] × 8 = 15y + 12
Write an equation in slope intercept form for the line that passes through the points (6,-3) and (0,2)
Answer: 14/6
Step-by-step explanation:
A line passes through point A(14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
Two lines that have the same slope and different y intercepts do not intersect at any points.

Step-by-step explanation:
they are all equal sides so what you'd do is 28+28+28= 84
Answer: 56
Step-by-step explanation: It's an equilateral shape so all sides are equal, so then both angle UVS and UTS are congruent to each other. But since it's asking for the whole angle T you can just do 28+28=56 and that's your answer. Hope I'm right
