Find the the slope of the line that contain 5,3 and -1,4
Answer:
-1/6
Step-by-step explanation:
the equation to do this is y2-y1/x2-x1
therefore you set it up as 4-3/-1-5
then when you simplify it it would be 1/-6
therefore the slope is -1/6
What is -86 + x = - 4x + 29
Answer:
x = 23
Step-by-step explanation:
Add 4x to the left and add 86 to the right.
5x = 115
Now, divide 5 on both sides to get x.
x = 23.
The result is 23.
Answer:
x= – 115/3

At the school's fall bake sale, all of the pies were cut into 6 pieces, so each person who bought a piece bought 1/6 of a pie. Each slice of pie sold for $1.00. How much money did the school make if all eleven pies were sold? (In other words, find 11 divided by 1/6 .)
Answer:
2 ⅓
Step-by-step explanation:
division is the same as a fraction
the dividend is the numerator and the divisor is the denominator
7÷3 is the same as 7/3
change 7/3 into a mixed number which is 2 ⅓
Brandon is half of Ella's age. Ella is three times Tristans age. In fifteen years, their combined age will be 89. How old is Brandon?
Answer:
Step-by-step explanation:
Let Brandon's age be [tex]x[/tex]
Therefore Ella=[tex]2x[/tex]
Tristan= [tex]\frac{2x}{3}[/tex]
Fifteen years time add 15 to each age
Brandon: [tex]x+15[/tex]
Ella: [tex]2x+15[/tex]
Tristan:[tex]\frac{2x}{3} +15[/tex]
All their ages together=89
So: [tex]x+15[/tex] + [tex]2x+15[/tex] + [tex]\frac{2x}{3} +15[/tex][tex]=89[/tex]
[tex]3\frac{2}{3} x=44[/tex]
[tex]x= \frac{44}{3\frac{2}{3} } =12[/tex]
FIRST TO ANSWER GETS MARKED BRAINLEST! please look at picture. The probability that a student guesses the correct answer to a four-choice multiple choice question is P(correct) = 0.25. How many correct answers should a student expect to guess on a test with 56 four-choice multiple choice questions?
A student should expect to guess_______correct answers.
Answer:

since there is 1/4 of a chance to get a question right by guessing you need to see what 1/4 of 56 is, which is 14
6 6 small bricks have the same mass as 5 large bricks. The mass of one small brick is 2.5 kg. What is the mass of one large brick?
Since 6 small bricks have the same mass as 5 large bricks and the mass of one small brick is 2.5 kg, the mass of one of the large bricks is 3 kg
What is mass?Mass is the quantity of matter in a physical body.
6 small bricks have the same mass as 5 large bricks.
let
the total mass of the small or large bricks = x
Therefore,
6 × 2.5 = x
x = 15 kg
Therefore, the mass of each large bricks can be calculated as follows:
let the mass of each large bricks = y
15 = 5y
divide both sides by 6
y = 15 / 5
y = 3 kg
Therefore, the mass of one of the large bricks is 3 kg

Write an exponential function in the form y=ab^x that goes through points (0,10) and (9, 5120).
The form [tex]y=ab^x[/tex] has two unknowns, namely [tex]a[/tex] and [tex]b[/tex], so you would need to have two points to find the equation (which you do). Once you have your two points, you can create a system of equations by plugging in the x and y coordinates like below:
[tex]\left \{ {{10=ab^0} \atop {5120=ab^9}} \right.[/tex]
One thing you may remember is that ANY number to the power of 0 equals 1. Knowing that, we can replace [tex]b^0[/tex] in the first equation with 1. Since 1 multiplied by any number is just that same number, that leaves [tex]a[/tex] alone in the first equation.
[tex]\left \{ {{10=a} \atop {5120=ab^9}} \right.[/tex]
The first equation now tells us that [tex]a[/tex] is 10, so we can plug 10 in for [tex]a[/tex] in the other equation.
[tex]5120=10b^9[/tex]
Now we can divide both sides by 10 to isolate [tex]b^9[/tex].
[tex]512=b^9[/tex]
To get [tex]b[/tex] alone, we have to take the 9th root of both sides.
[tex]\sqrt[9]{512} =\sqrt[9]{b^9}[/tex]
That gives us:
[tex]2=b[/tex]
We can now plug [tex]a[/tex] and [tex]b[/tex] into the form they gave us to get:
[tex]y=10*2^x[/tex]

A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures u = the true mean amount of time
it takes to fully charge a battery pack.
Is it plausible that the true mean number of hours to charge all battery packs of this type may be 5?
O No, this is not a plausible value for the population mean, because 5 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
O Yes, this is a plausible value for the population mean, because 5 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because the lower bound of the confidence interval, 5.2, is
greater than 5.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
====================================================
Explanation:
The greek letter mu is the population mean. It has the symbol [tex]\mu[/tex] which looks like the letter 'u' but with a tail at the front or left side.
The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8
We see that 5 is not in that interval. It's a bit to the left of 5.2
Since mu = 5 is not in the interval, it's not a plausible value for the population mean.
Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.
the total of 3/4 and a number is no more than 2
3/4=a fraction
Answer:
Step-by-step explanation:
Let the number be x
[tex]\dfrac{3}{4}+x \leq 2\dfrac{3}{4}\\\\\\\dfrac{3}{4}+ x \leq \dfrac{11}{4}[/tex]
Subtract 3/4 from both sides
[tex]\dfrac{3}{4}-\dfrac{3}{4}+x\leq \dfrac{11}{4}-\dfrac{3}{4}\\\\\\x \leq \dfrac{11-3}{4}\\\\\\x \leq \dfrac{8}{4}\\\\\\x \leq 2[/tex]

Answer:
69°Step-by-step explanation:
Complementary angles sum to 90°.
We have the measure of one angle, find the missing one as below.
