Answer:

Answer:

7.8 mL

Step-by-step explanation:

Answer:

.78 L

Step-by-step explanation:

Well, simple conversions

a milliliter is .0001 of a liter and 1 liter is 1000 mL, so we can safely say that .78 L is 780 mL, dwarfing the given 7.8 mL

Answer:  21 units

Step-by-step explanation: Since the y-coordinates are the same, you need to find only the difference in the x-values.

Since one is positive and one is negative, (on different sides of the y-axis) you add the distances of each coordinate from there.

Or, remember that finding the difference between two numbers is a subtraction equation, and subtracting a negative is the same as adding a positive.

15 -(-6) = x

15 + 6 = x

21 = x

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]

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

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

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  

Answer:

p=1

Step-by-step explanation:

first you need to get rid of the parenthesis

-2p+8=6-7p+7

then combine everything you can on their respective sides

-2p+8=13-7p

then get the variable on one side and for this, it can be done 2 different ways but both ways get the same answer

-2p+8=13-7p

+7p         +7p

5p+8=13

or

-2p+8=13-7p

+2p         +2p

8=13-5p

then, depending on which way you decide to solve it, you would then solve for x like you would in any regualar equation

first way shown above:

5p+8=13

    -8  -8

5p=5

divide them both by 5 and p=1

or the other way shown above

8=13-5p

-13  -13

-5=-5p

divide both sides by -5 and then p=1

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.

Step-by-step explanation:

Here, 1:x =5:15

Solving which the value of x is 3.

Solution:

We know that:

Since LN and MP must be equation, equation formed: 4x + 3 = 8x - 9

Let's simplify the equation to find x.

Subtracting 4x both sides.

Add 9 both sides.

Divide 4 both sides.

Now, let's find the length of each diagonal.

Diagonals are equal
