An experimental drug has been shown to be 75% effective in eliminating symptoms of allergies in animal studies. A small human study involving six participants is conducted. What is the probability that the drug is effective on half of the participants?
Answer:
[tex]P(x=3) = 0.1318[/tex]
Step-by-step explanation:
The question illustrates a binomial distribution and the given parameters are:
Given
[tex]n = 6[/tex] -- sample size
[tex]p = 0.75[/tex] --- probability of success
[tex]r = 3[/tex] --- half of the participant
Using the binomial probability formula, we have:
[tex]P_x = ^nC_xp^x(1-p)^{n-x}[/tex]
For x = 3, the probability is:
[tex]P(x=3) = ^6C_3*0.75^3 * (1-0.75)^{6-3}[/tex]
[tex]P(x=3) = 20*0.75^3 * 0.25^3[/tex]
[tex]P(x=3) = 0.1318[/tex]

Liam mixed together quarts of orange juice and quarts of pineapple juice. Then he added quarts of seltzer to make punch. How much more juice than seltzer did Liam use to make punch?
Answer:
[tex]2\frac{1}{4}[/tex]
Step-by-step explanation:
Question has missing details (See attachment).
Given
[tex]Orange\ Juice = 1\frac{1}{4}quart[/tex]
[tex]Pineapple\ Juice = 2\frac{1}{2}quart[/tex]
[tex]Seltzer = 1\frac{1}{2}quart[/tex]
Required
Determine how much juice than seltzer used.
To do this, we first calculate the total amount of juice
[tex]Juice = Orange + Pineapple[/tex]
[tex]Juice = 1\frac{1}{4} + 2\frac{1}{2}[/tex]
[tex]Juice = \frac{5}{4} + \frac{5}{2}[/tex]
Take LCM
[tex]Juice = \frac{5+10}{4}[/tex]
[tex]Juice = \frac{15}{4}[/tex]
Then subtract the amount of seltzer used.
[tex]Juice - Seltzer = \frac{15}{4}-1\frac{1}{2}[/tex]
[tex]Juice - Seltzer = \frac{15}{4}-\frac{3}{2}[/tex]
Take LCM
[tex]Juice - Seltzer = \frac{15 - 6}{4}[/tex]
[tex]Juice - Seltzer = \frac{9}{4}[/tex]
[tex]Juice - Seltzer = 2\frac{1}{4}[/tex]
The amount of juice used more than seltzer is [tex]2\frac{1}{4}[/tex]
Answer: 3 3/4 quarts

The gas tank in dad’s car holds 12 gallons. The gas tank in mom’s truck holds 50% more than that. How much gas does the truck’s tank hold?
Answer:
To calculate this you just have to calculate a rule of three with both gas tanks, so if the dad´s car holds 12 gallons of gas, and the mom´s car holds 50% more that means 150% of in the rule of three: So the total amount of gallons that the mom´s car tank can hold is 18 gallons.

Step-by-step explanation:
For A
The name of two similar triangles is ABC and CED.
For b
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
Here
< BAC = < CED ( given)
<ACB = < ECD ( vertically opposite angles)

Find the area of a circle with the diameter of 3 cm use 3.14 for pi
Answer:
47.065
Step-by-step explanation:
The formula for area of a circle is A = πr^2
Since the diameter is double the radius, divide 3 in half to get 1.5.
Then plug your numbers into the equation and remember to start with exponents.
3.14 x 1.5^2 or 3.14 x (1.5 x 1.5)
Answer:
7.07 cm
Step-by-step explanation:
Area of a circle = πr²
{diameter = 3 cm ; radius = 3/2 = 1.5 cm}
πr²
= 3.14 x (1.5)²
=3.14 x 2.25
= 7.07 cm (approx)

6,000
meters
kilometers
8,000
9,000
5
7
Answer:
Remember while answering, 1 kilometer = 1,000 meters
5,000 ⇒ 5
6,000 ⇒ 6
7,000 ⇒ 7
8,000 ⇒ 8
9,000 ⇒ 9
Step-by-step explanation:
1 kilometer is 1,000 meters because "kilo" means 1,000
Knowing this we can make an equation to figure this out
When we know x, or meters, we can do y = x/1,000
When we know y, or kilometers, we can do x = 1,000y

I need it in its simplest form.
A 6-foot person standing 20 feet from a streetlight casts a 5-foot shadow. Two similar triangles are formed. One triangle is formed by the person and the shadow that the person casts. A second triangle is formed by the streetlight and the ground from the base of the streetlight to the end of the shadow.
The street light is __ times taller than the person.
Answer:
2 times taller
Step-by-step explanation:
[tex]\frac{6}{10} = \frac{x}{20}[/tex]
120=12x
x = 12ft
x=height of street light
the street light is 12 feet tall so the street light is 12 times taller than the person
I don't know what's the ten but anyway, "Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5-pound bags can Roberta fill? Does she have any left over?" what is the other answer?
Answer:
She can put fill 2 “2/5 pound bags” and will have 1/5 pounds of raisins remaining.
Step-by-step explanation:
First we change the 2/5 into common denominators by multiplying by 2 and we go from 2/5–>4/10. Now that we have this we can see how many times 4 goes into 9 which is 2 so we know that she can fill 2 “2/5 pound bags.” But 4/10x2=8/10 and since we have 9/10 pounds of raisins we subtract 8/10 from 9/10 to get a difference of 1/10. So we have 1/10 pounds of raisins remaining and she can fill 2 full bags of “2/5 pound bags.”
Use the diagram below to find x and each missing angle.
Points P and Q are equidistant
from à Common point n on a bearing
of 300 degree and 20 degree respectively. Find
the bearing of
Q From P.
The bearing of point Q from point P is 80 degrees.
To find the bearing of point Q from point P, we need to determine the angle between the bearing of point P from the common point N and the bearing of point Q from the common point N.
Given that point P is on a bearing of 300 degrees from the common point N, and point Q is on a bearing of 20 degrees from the common point N, we can find the bearing of Q from P as follows:
Calculate the angle between the bearing of P from N and the bearing of Q from N:
Angle = Bearing of Q from N - Bearing of P from N
Angle = 20 degrees - 300 degrees
Angle = -280 degrees
Adjust the angle to be within the range of 0 to 360 degrees:
Since the angle is negative, we can add 360 degrees to it to bring it within the range of 0 to 360 degrees:
Adjusted Angle = -280 degrees + 360 degrees
Adjusted Angle = 80 degrees
Therefore, the bearing of point Q from point P is 80 degrees.

Answer:
[tex] A_{sector} \approx \: 80.38 \: {ft}^{2} [/tex]
Step-by-step explanation:
[tex] A_{sector} = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ A_{sector} = \frac{144 \degree}{360 \degree} \times 3.14 \times {(8)}^{2} \\ \\ A_{sector} = 0.4 \times 3.14 \times {(8)}^{2} \\ \\ A_{sector} = 80.384 \\ \\ A_{sector} \approx \: 80.38 \: {ft}^{2} [/tex]

through: (-2,-5), slope = 4
Standard form from a point to a slope
Answer:
4x-y+3
Step-by-step explanation:
When we are given two points and asked to find the equation of the line, we must find the slope first. After that, it is the same three steps: substitute, distribute, solve for y. You should now be able to write the equation of a line in: point-slope form, slope-intercept form, or standard form
