No
Step-by-step explanation:
here's a little trick, add a zero to make both numbers the same.
it's doesn't change the value.
so .27 and .3 become .27 and .30
and .30 is greater
Question 1 of 10
Which best describes the meaning of the statement "If A, then B?
A. If A is false, then B must be false.
B. If A is false, then B might be false.
ОО ОО
C. If A is true, then B might be true.
D. If A is true, then B must be true.
SUBMIT
Answer:
I believe it would be D
Step-by-step explanation:
Since it implies that if A is true, then B is true, it would be D.
"If A" implies that it can be both true or false, but "then B" implies that it must be B if A is true.
Hence my choice of D.
Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.8. If they have three children, what is the probability that exactly two of their three children will have that trait? Round your answer to the nearest thousandth
Answer:
0.384 = 38.4% probability that exactly two of their three children will have that trait.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either they have the trait, or they do not. The probability of a child having the trait is independent of any other child. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.8.
This means that [tex]p = 0.8[/tex]
Three children:
This means that [tex]n = 3[/tex]
What is the probability that exactly two of their three children will have that trait?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{3,2}.(0.8)^{2}.(0.2)^{1} = 0.384[/tex]
0.384 = 38.4% probability that exactly two of their three children will have that trait.
Six chicken nuggets have 204 calories. How many calories are in 9 chicken nuggets
Answer:
306 calories
Step-by-step explanation:
By looking at the problem, we can conclude the number of chicken nuggets and the calories are directly related, when the amount of chicken nuggets go up, the calories also go up, proportionally. Because of this, we can set up an equation:
6 / 204 = 9 / x
Where x is the amount of calories in 9 chicken nuggets.
Now, we can simplify by cross multiplying:
6x = 1836
x = 306 calories
Answer:
306 calories
Step-by-step explanation:
The table represents a proportional relationship. Complete the table and write an equation that describes the relationship

A regular hexagon has a perimeter of 127 m. Find its area to the nearest tenth.
Answer:
1164.01
Step-by-step explanation:
First you realize there is 6 sides on a hexagon. Then, you divide the 127 by 6. Then you split the hexagons into 6 parts. This leads you to a triangle. Then if you divide the degrees so 360 total degrees/6 parts = 60. If you split that triangle in half, the angle becomes 30 degrees. Then you will realize the 30 degree is pointed at the 127/12. Because you know the x, (x)(Square root 3), 2x theorem (the 30, 60, 90 triangle), you get the height of the triangle which is about 18.33 . Then you do the area of Triangle = 1/2 * base * height. Therefore you should get 194.00 Because there is 6 parts to a hexagon, you then need to multiply by 6. Your final answer should be 1164.01. This should be correct, please correct me if I’m wrong, thanks.

A biased 4-sided dice is rolled. possible scores are 1,2,3 or 4. The probability of rolling a 1,3 or 4 is shown below. what is the probability of rolling a 2?
Answer:
0.2
Step-by-step explanation:
A probability is always out of 100% (which also means out of 1)
So the probability that the dice rolls a 1 is 0.15/1, the probability it rolls a 3 is 0.3/1 and the probability it rolls a 4 is 0.35/1. The probability it rolls a 2 is x/1 where x is what we're looking for. If you add all the probabilities up you should have 1 in total. So 0.15 + x + 0.3 + 0.35 = 1
So to find the missing one you need to subtract all the probabilities you know from 1:
1 - 0.15 - 0.3 - 0.35 = 0.2
The probability of the die rolling 2 is 0.2
What is probability?Probability is a measure of the likelihood of an event occurring. The probability of all the events in a sample space adds up to 1.
Given here the probabilities are 0.15,0.3, 0.35
since the probabilities, all add upto 1
therefore P(2) = 1-(0.15+0.3+0.35)
= 0.2
Hence the probability that the die will roll 2 is 0.2

Solve: 4 (x + 2.5) = 48
Answer:x=19/2
Step-by-step explanation:
4(x+2.5)=48
Step 1: Simplify both sides of the equation.
4(x+2.5)=48
(4)(x)+(4)(2.5)=48(Distribute)
4x+10=48
Step 2: Subtract 10 from both sides.
4x+10−10=48−10
4x=38
Step 3: Divide both sides by 4. 4x/4 = 38/4 = 19/2
Answer:
4(x + 2.5) = 48.
4x + 4 x 2.5 = 48.
4x + 10 = 48.
4x + 10 -10 = 48 -10
4x = 38
Divide both sides by 4.
X = 9.5.
X = 10 if approximated.

7x+8y= 8
Slope
Y intercept
Answer:
Slope = -7/8
Y-intercept = (0, 1)
Step-by-step explanation:
Answer:
[tex]slope = - \frac{7}{8} [/tex]
y- intercept= 1
Step-by-step explanation:
Rearrange the equation such that it is in the form of y=mx+c. This form is known as the slope-intercept form, and m is the gradient while c is the y-intercept.
7x +8y= 8
8y= -7x +8
Divide by 8 on both sides:
[tex]y = - \frac{7}{8} x + 1[/tex]
Thus, the slope is [tex] - \frac{7}{8} [/tex] and the y-intercept is 1.
Another way to find the y-intercept is to substitute x= 0 into the equation since the y-intercept occurs at x= 0.
7x +8y= 8
When x= 0,
7(0) +8y= 8
8y= 8
y= 8 ÷8
y= 1
Thus, the y-intercept occurs at y= 1 or the coordinate (0, 1).
Note: slope and gradient have the same meaning and can be used interchangeably

Answer:
60°
Step-by-step explanation:
You recognize the ratio of the long side to the short side as 2 : 1, so you know this is the 1 : √3 : 2 "special" triangle that has angles 30°, 60°, 90°. The angle of interest is opposite the longer side, so is the 60° angle.
x° = 60°
_____
In case you don't remember the "special" 30-60-90 and 45-45-90 right triangles, you can use the relevant trig function:
Cos = Adjacent/Hypotenuse
cos(x°) = 16/32 = 1/2
x° = arccos(1/2)
x° = 60°

Figure A maps to figure B with a scale factor of 0.25
Answer:
x would be 6
Step-by-step explanation:
This is becuase since the scale factor from Fig A to B is 0.25, the length of all of the sides follows this rule.
Since x on Fig A and 1.5 on Fig B are corresponding sides, you can do:
x * 0.25 = 1.5
x * 0.25 (4) = 1.5 (4)
x * 1 =6
x = 6

What is the measure of BPC?
Answer:
[tex]\angle BPC=100^{\circ}[/tex]
Step-by-step explanation:
Assuming P is the center of the circle:
The angle BPC encompasses arc BC. Notice angle CEB also encompasses this arc and the measure of angle CEB is given as [tex]50^{\circ}[/tex]. The measure of an angle with a point on the circle that encompasses an arc is equal to half of the measure of an angle with a point on the center of circle.
