A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.
The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?
Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.

Explain what you did to get your answer.
help me this and ill give brainliest
Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

Answer:
B
Step-by-step explanation:
∠ AEB and ∠ ADC are corresponding angles and are congruent, then
3x - 10 = x + 40 ( subtract x from both sides )
2x - 10 = 40 ( add 10 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25

Count how many number there are and put them in the table.
There are 4 consecutive even integers that add up to 268. Which integers are they?
Answer:
4n+ 12 = -268, or 4n = -280, or n = -70. This would imply that the four consecutive ODD integers are -70, -68, -66, -64.

Mrs. Foust wants to know Aziza’s age. She knows that Aziza is the middle child. Her sister, Capri, is 4 years older than Aziza, and her sister, Portia, is 5 years younger than Aziza. The sum of their ages is 38. Let a represent Aziza’s age. Which statements are true about this scenario? Check all that apply.
Answer:
The expression that represents Capri’s age is a + 4.
The expression that represents Portia’s age is a – 5.
Step-by-step explanation:
The expression that represents Capri's age is a + 4.
The expression that represents Portia's age is a -5.
To write an equation for this scenario, Capri's age needs to be equal to Portia’s age
The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.
Solving this equation will give Aziza's age.
Aziza'a age = a
Portia age = a - 5
Capri's age = 4 + a
a + a - 5 + 4 + a = 38

You and your friend were working the ticket table at the last school basketball game.
The tickets sold for $5 for adults and $3 for students.
A total of 375 people attended the
game and a total of $1375 was taken in at the ticket table. How many adult tickets were
sold and how many student tickets were sold?
Answer:
Step-by-step explanation:
First
a+s=375
a=375-s
Next
5a+3s=1375, now using a found above makes this equation become
5(375-s)+3s=1375
1875-5s+3s=1375
1875-2s=1375
-2s=-500
s=250, since a=375-s
a=375-250
a=125
So 125 adult and 250 student tickets were sold.

What property do we use when we find equivalent fractions?
Answer:
It's called the cross multiply rule. The rule is shown below: This formula says that if the numerator of one fraction times the denominator of the other fraction equals the denominator of the first fraction times the numerator of the second fraction, then the fractions are equivalent.

1. Write the slope-intercept form of the equation that passes through the point (0, 1) and is parallel to the line y = 3x - 5
O y = 3x + 1
O y = 3x - 4
O y = -1/3x - 4
O y = -1/3x + 1
Answer:
y = 3x + 1
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is Y = 3X - 5. Its slope is 3. A line parallel to this one will also have a slope of 3.
Plug this value (3) into your standard point-slope equation of y = mx + b.
y = 3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (0, 1). Plug in the x and y values into the x and y of the standard equation.
1 = 3(0) + b
To find b, multiply the slope and the input of x (0)
1 = 0 + b
Now, add 0 to both sides to isolate b.
1 = b
Plug this into your standard equation.
y = 3x + 1
This equation is parallel to your given equation (y = 3x - 5) and contains point (0, 1)
Hope this helps!
Help me with this!!! Fake answers will get reported
Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right
