From the given graph the value of μ is 530 and the value of σ is 15.

In the Normal Curve the value at which the shape of the graph is highest is called it's mean(μ) and the value on the left of mean is μ-σ and the value on the right of the mean is μ + σ .

In the Given question

the shape of the graph is highest at 530,

hence the value of mean(μ) = 530.    ....(i)

we know that the value on the left of mean is μ-σ .....(ii)

From the graph the value to the left of mean(μ) is 515.    ...(iii)

Equating equation (ii) and (iii) we get ,

μ-σ = 515

Substituting the value of  μ from equation (i) we get ,

530 - σ = 515

σ = 530 - 515

σ = 15

Therefore , From the graph the value of μ is 530 and the value of σ is 15.

The missing coordinate of the ordered pair (-4, m) for the equation 6x - 4y = 9 is -33/4.

Let the missing ccordinate of the ordered pair be m.

According to the given question.

We have an equation 6x - 4y = 9.

Here, we have given a ordered pair (-4, ?) which satisfy the given equation 6x - 4y = 9.

Therefore, the missing coordinate of the ordered pair (-4, m) for the equation 6x - 4y = 9 is given by

6x - 4y = 9

⇒ 6(-4) - 4(m) = 9

⇒ -24 - 4m = 9

⇒ -4m = 9 + 24

⇒ -4m = 33

⇒ m = -33/4

Hence, the missing coordinate of the ordered pair (-4, m) for the equation 6x - 4y = 9 is -33/4.

Answer:

It is the second answer [tex]3^{8} b^{10}[/tex]

Step-by-step explanation:

This is easier to understand if you write it out in expanded form.

[tex](3^{4} b^{5}) ^{2}[/tex]  means

[tex](3^{4} b^{5})[/tex][tex](3^{4}b^{5)}[/tex]  We do this twice because that is what the exponent tells us to do that is outside of the parentheses.

Now write this out in expanded form and we will have

(3x3x3x3xbxbxbxbxb)(3x3x3x3xbxbxbxbxb)  If we put all of the 3's and b's together we get

3x3x3x3x3x3x3x3xbxbxbxbxbxbxbxbxbxb

the power of powers principle tells us that when we have an exponent raised to an exponent, we multiple the exponents. (4 x 2 = 8 and 5 x 2 = 10)

The principal is $145 .

Simple interest is the interest amount for a particular principal amount of money at rate of interest. The interest is calculated by multiplying the principal with the time and rate. The total amount after a certain time is given by the sum of the  principal and the interest for that time.

The formula for calculating the Interest on a Principal(P) , time(t) and rate(R).

Interest=P×R×t

Now let us consider the principal to be P.

Time(t)=5 years

Simple Interest(I)=$87

Rate(R)=12%=0.12

Now let us find the principle for the this interest using the above formula.

I=P×R×t

Substituting the given values we calculate the Principal(P).

[tex]87=P\times0.012\times5\\or,P=87\div(0.012\times5)\\or,P=87\div0.6\\or,P=145[/tex]

Therefore the Principal for the simple interest of $87 for 5 years at rate of 12% is $145.

Answer:

practice to do your self

Step-by-step explanation:

it seems there is some trick question involved.

we find such answers by putting a horizontal line through the y points and see, where the horizontal line is intersecting the function graph and go straight down to the x-axis to see the value of x for that y value.

the horizontal line through y = -1.5 does not intersect at all.

so, in one hand the answer is "no solution".

but on the other hand, we could assume that the function graph continues further to the right (and down).

and then the intersection point would be

(7.5, -1.5),

and the corresponding x = 7.5.

for y = 0 the horizontal line is the x-axis itself. so, for what values of x does the x-axis intersect the function curve ?

at x = -3, and at x = 6.

for y = 2 the corresponding horizontal line is intersecting the function curve at

x = -2.125 (it looks like it is at the half of the half of the half unit as the grid unit left of -2, so it is -2 - 1/2³ = -2 1/8 = -2.125)

x = 0.5

x = 4 (it just touches the tip of the curve there)

for y = 2.5 there is truly no solution. that horizontal line does not intersect the function curve at any point.

The patient should take three-tenths of a tablet every 4 hours and the infusion rate is 0.13 mL per 12 hours.

Given that, a doctor administers a drug to a ​34-kg ​patient, using a dosage formula of ​55mg/kg/day.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of tablets should a 34​-kg patient takes every four​ hours to be x.

Now, 55 × 34 = 1870 mg/day

For every four hours:

1870 × 1 /24 × 4 = 311.666

≈312 mg per 4 hours

So, x=312/4 × 1/300 = 78 × 0.0033

=0.26 tablet

Liquid suspension is for every 12 hours:

So, 312/12 × 1/200 = 26 × 0.005 = 0.13 mL

Hence, the patient should take three-tenths of a tablet every 4 hours and the infusion rate is 0.13 mL per 12 hours.

if u solve the problem normally then it gives 0/0 form so

x(2x^2-1)/3x cross out the numerator and denominator x and x from 3x then keep 0 in place of x.

(2 x 0 ^2-1)/3 = -1/3

since the function is continuous at x = 0 so n = -1/3

Step-by-step explanation:

so after five months, the costs would equal each other.

Explanation:

You'd have to write equations for the price per month for each club.

Let x equal the number of months of membership, and y equal the total cost. Club A's is y=25x+40 and Club B's is y=30x+15.

Because we know that the prices, y, would be equal, we can set the two equations equal to each other.

25x+40=30x+15.

We can now solve for x by isolating the variable.

25x+25=30x.

25=5x.

5=x

After five months, the total cost would be the same.

Step-by-step explanation:

To get your answer, you would want to use the expression -3.5/60. So your answer will be -0.058.

Answer:

The number is -2

Step-by-step explanation:

First let's turn this into an equation

5 times a number (we'll use x) + 34 = 24

5x+34= 24

Now to start solving the problem

First thing's first, let's carry over the 34 to the other side by subtracting 34 from both sides. This helps us try to get x by itself

5x+34 = 24

     -34     -34

5x = -10

Now we just divide both sides by 5 to get rid of it entirely from the x

5x = -10

/5      /5

x = -2

Your number should be -2

We can also check by plugging -2 back into the equation for x

5 (-2) +34 = 24

-10 +34 = 24

24 = 24

Since they are both equal, -2 is really your answer

The number of line segments in the 100th pattern is equal to 201 line segments.

Triangles are polygons with three sides of equal length, herein we find constructions elaborated with equilateral triangles, in which two new line segments are added when an equilateral triangle is so. Then, the number of line segments can be modelled after the following linear progression formula:

n = 3 + 2 · (n - 1)

Where n is the number of equilateral triangles in the pattern.

If we know that n = 100, then the number of line segments is:

n = 3 + 2 · (100 - 1)

n = 3 + 2 · 99

n = 3 + 198

n = 201

The number of line segments in the 100th pattern is equal to 201 line segments.
