the probability is 68‰

For the normal distribution,

The scores on standardized admissions tests are normally distributed with a mean of 500

Mean (μ)=500

standard deviation(σ)=100

The probability that scores lies between 400 and 600  i.e, P(400

For the standard normal distribution curve

Z=(x-μ)/σ

(400-500)/100<(x-μ)/σ<(600-500)/100

-1

For standard normal distribution mean shifted to zero,  P(x)dx=1/(sqrt(2pi))e^(-z^2/2)dz.

so the probability would be 68‰

The probability that the coin will land heads up on the first flip, tails up on the second flip, and tails up on the third flip is (1/8).

If we toss a coin, we have two possible outcomes: head or tail. Now:

P(E) = Favourable outcomes / Total outcomes

      = 1/2

As per the question, we need heads on the first throw and tails on the next two throws. We know that for independent events:

P(A∩B∩C) = P(A)*P(B)*P(C)

Let A be the event of getting head on the first throw and B and C be events of getting tails on the second and third throws of dice respectively.

P(A) = P(B) = P(C) = 1/2

So, P(A∩B∩C) = (1/2)*(1/2)*(1/2) = 1/8

So, the Required probability is (1/8)

The linear function that represents the graph of that has the points on the table is: A. .f(x) = 32(3x - 1).

If a point is on a graph of a linear function, its coordinates will make the equation of the linear function true, if plugged into the equation.

Given the table that represents some of the points that are on a linear function graph, use one point, (1, 64), to check which of the functions represents the table.

Substitute x = 1 and .f(x) = 64 into each of the functions given to see which is true:

.f(x) = 32(3x - 1)

64 = 32(3(1) - 1)

64 = 32(3 - 1)

64 = 32(2)

64 = 64 [true]

.f(x) = -32(x - 3)

64 = -32(1 - 3)

64 = 64 [true], however, if we use another set of values, say (5, 448), this function will not be true.

.f(x) = -2(32x - 3)

6 = -2(32(1) - 3)

6 = -2(29)

64 = -58 [not true]

.f(x) = 16(2x - 1)

64 = 16(2(1) - 1)

64 = 16(1)

64 = 16 [not true]

Therefore, the function that represents the table is: A. .f(x) = 32(3x - 1).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

The equation A = 9 - ( 8/S )

Now , when S = 4

Substitute the value of S = 4 in the equation , we get

Answer:

Step-by-step explanation:

first category and fifth one up

After solving the system of equation we will get

x = 5y/2 +1  

y = 2/5- 2x/5

First equation is written

−2x+5y=−2

Subtract 5y from both sides.

−2x =−2−5y

The equation is in standard form.

−2x=−5y−2

Divide both sides by −2.

-2x/-2 = -5y-2/ -2

Dividing by −2 undoes the multiplication by −2.

x= −5y-2/-2

​Divide  −2−5y  by −2.

so

x= 5y/2 + 1

Now the second equation is

4x−10y=4

Add 4x to both sides

-10y = 4-4x

The equation is in standard form.

Divide both sides by 10

-10y/10= 4-4x/10

Dividing by 10 undoes the multiplication by 10.

y= 4-4x/10

Divide 4-4x by 10.

so

y= 2/5- 2x/5

Answer:

[tex] \sf \: h(1) = - 1[/tex]

Step-by-step explanation:

Given equation,

→ h(x) = -3x + 2

Now the value of h(1) will be,

→ h(x) = -3x + 2

Answer:

To use coordinates on a coordinate grid, you first need to determine the scale of the grid, which is represented by the proportion M=24R. This means that for every 24 units on the grid, the corresponding real-world distance is equal to R units.

Once you have determined the scale of the grid, you can use the coordinates to locate points on the grid. To do this, you will need to know the coordinates of at least one point on the grid, which is known as the origin. The origin is typically represented by the coordinates (0,0).

To find the coordinates of a point on the grid, you can use the following steps:

For example, if you wanted to find the coordinates of a point that is 5 units to the right of the origin and 3 units above the y-axis, the coordinates of the point would be (5, 3).

We then regroup terms into two proportional parts: (48x² +8x) + (30x + 5)

Factor the expression: 8x(6x + 1) + 5(6x + 1)

We then factor 8x(6x + 1) + 5(6x + 1) to (6x + 1)(8x + 5)

Now that we know (ax + b) and (cx + 1) is (6x + 1)(8x + 5) we just need to apply the numbers to their corresponding letters:

1.46% probability that fewer than 700 children received their vaccine.

What is probability?

The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.

Here, we have

95% of children have received their DTaP vaccine p = 0.95

Sample of 750, n = 750

For the approximation, the mean and the standard deviation are given by:

u = np = 750×0.95 = 712.5

σ = [tex]\sqrt{np(1-p)}[/tex]

σ = [tex]\sqrt{750(0.95)(0.05)}[/tex]

σ = 5.97

Using continuity correction, the probability that fewer than 700 children received their vaccine is P(X < 700 - 0.5) = P(X < 699.5), which is the p-value of Z when X = 669.5.

Z = X-u/σ

Z = 669.5 - 712.5/5.97

Z = - 2.18

The p-value of Z = - 2.18 is 0.0146.

Hence, 1.46% probability that fewer than 700 children received their vaccine.

Answer:

The correct equations are 2x +3y=100 and x+y=48. These equations can be used to find the number of multiple-choice and free response questions on the test. The first equation, 2x +3y=100, shows that the total number of points for the multiple-choice questions (2x) plus the total number of points for the free response questions (3y) equals 100. The second equation, x+y=48, shows that the total number of multiple-choice and free response questions on the test is equal to 48. These equations can be solved simultaneously to find the values of x and y.

Its means that the addition of natural numbers obeys the closure property.

In mathematics, the closure property is a property that states that if a set is combined with all its limit points, then the combined set is also a limit point. The closure property applies to sets of real numbers, vectors, and matrices. It states that the closure of a set is itself, i.e., the set is closed under the given operation. The phrase "closed under addition" means that when two natural numbers are added together, the result is also a natural number. In other words, natural numbers are part of a closed system concerning addition; the addition operation always produces another natural number.

The theorem that proves that the triangles are congruent is the Side-Side-Side (SSS) Congruence Theorem.

The Side-Side-Side (SSS) Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This theorem is useful for proving that two triangles are congruent without having to use angles. The SSS Congruence Theorem is a useful tool for solving geometry problems involving triangles. It can be used to find the unknown side length of a triangle given the lengths of the other two sides, or in more complicated proofs involving multiple triangles. This theorem is also helpful in determining the area of a triangle, as the area is proportional to the product of the lengths of the sides.

y = 3x – 2 is the equation of the line which passes through 1/3 and 2 5 with slope.

We can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope and b is the y-intercept. We know one point on the line, which is (1/3, 2.5). We can calculate the slope by calculating the rise (change in y) divided by the run (change in x), which is (2.5 - 0) / (1/3 - 0) = 2.5 / 0.33 = 7.5. Therefore, the equation of the line is y = 7.5x + b. To solve for b, we can substitute in our point, (1/3, 2.5) into the equation. We get 2.5 = 7.5(1/3) + b, or 2.5 = 2.5 + b. Therefore, b = 0, and the equation of the line is y = 7.5x + 0, or y = 7.5x.
