A study shows that 78% of adults need eye correction. If 12 adults are randomly selected, find the probability that atleast 11 of them need correction for their eyesight
Answer: 0.2224
Step-by-step explanation:
Given: The proportion of adults need eye correction: p= 78%=0.78
Let X be a binomial variable that represents the number of adults who need eye correction.
Sample size of adults: n= 12
Binomial ditsribution formula:
[tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]
Now, the probability that at least 11 of them need correction for their eyesight will be
[tex]P(X\geq11)=P(X=11)+P(X=12)\\\\=^{12}C_{11}(0.78)^{11}(1-0.78)^{1}+^{12}C_{12}(0.78)^{12}(1-0.78)^{0}\\\\=(12)(0.78)^{11}(0.22)+(1)(0.78)^{12}(1)\\\\\approx0.1716503+0.05071486=0.22236516\approx0.2224[/tex]
Hence, the required probability = 0.2224

The following is an isosceles trapezoid, find WX
Answer:
WX=33
Step-by-step explanation:
Isosceles Trapezoid
The base angles of an isosceles trapezoid are congruent. The base angles of the trapezoid shown in the figure are P and Q, and S and R.
Midsegment Theorem: The length of the midsegment of a trapezoid is the average of the lengths of the bases.
Being W and X the midsegments of PS and QR respectively, then WX is the midsegment of PQ and SR, thus
[tex]\displaystyle WX=\frac{PQ+SR}{2}[/tex]
[tex]\displaystyle WX=\frac{27+39}{2}=\frac{66}{2}=33[/tex]
WX=33

Write the equation of the line that passes through (-3, -20) and (1,4).
Answer:
y=6x-2
Step-by-step explanation:
The equation of the line is y=mx+b
FINDING SLOPE: To find the slope of a given line use the equation [tex]\frac{y2-y1}{x2-x1}[/tex]
So x1=-3, y1=-20 and x2=1, y2=4
Plug those numbers into the equation: [tex]\frac{4-(-20)}{1-(-3)}[/tex] and we get the slope which is 6.
FINDING Y-INTERCEPT: Then we find the y intercept by plugging in our points (you can choose) I will use (1,4) and solve.
y=6x+b
4=6(1)+b
b=-2
Nolan plots the y-intercept of a line at (0, 3) on the y-axis. He uses a slope of 2 to graph another point. He draws a line through the two points. Which equation represents Nolan’s line?
y = 2x + 1
y = 2x + 3
y = 3x + 2
y = 3x + 5
Answer:
The equation of Nolan's line is [tex]y=2x+3[/tex]
Step-by-step explanation:
The slope-intercept form of a line is given by:
[tex]y=mx+b[/tex]
Here
m is the slope of the line
and b is the y-intercept.
Given
y-intercept = b = 3
slope = m = 2
The values of m and b can be put into the equation to find the line's equation
So,
Putting the value
[tex]y = 2x+3[/tex]
Hence,
The equation of Nolan's line is [tex]y=2x+3[/tex]
Answer:
The answer is y 2x + 3.

Allison is planning a bridal shower for her daughter. She has decided on a budget of $3,000 to pay for expenses in her & budget categories of venue, food, dessert, and 1 thank you gifts. Allison has budgeted $1,750 for food and dessert. She wants to spend of the remaining money in her budget on the venue, and on thank you gifts, How 1 much money will Allison budget for the venue? How much money will she budget for thank you gifts
Answer: Allison will budget $937.50 for the venue and $312.50 for thank-you gifts.
Step-by-step explanation:
Subtract $1,750 from Allison's budget of $3,000 to see how much Allison can budget for the venue and thank-you gifts.
$3,000-$1,750=$1,250
Allison can budget $1,250 for the venue and thank-you gifts.
Multiply $1,250 by 3/4 to calculate how much money Allison will budget for the venue.
$1,250⋅34=$937.50
Multiply $1,250 by 1/4 to calculate how much money Allison will budget for thank-you gifts.
$1,250⋅1/4=$312.50
Allison will budget $937.50 for the venue and $312.50 for thank-you gifts.
