I need to know ASAP what’s the missing number?

Answer:

When two parallel lines are cut by a transversal, Alternate interior angles are supplementary.

Step-by-step explanation:

(a) Therefore, the z-value for an area of 0.08 to the right of z is -1.41. (b) Therefore, the z-value for an area of 0.025 to the right of z is -1.96. (c) Therefore, the z-value for an area of 0.05 to the right of z is -1.64. (d) Therefore, the z-value for an area of 0.10 to the right of z is -1.28.

To answer this question, we need to use the standard normal distribution table (also called the z-table or appendix table). This table gives the area under the standard normal curve to the left of a given z-value.
(a) To find the z-value for an area of 0.08 to the right of z, we can subtract the area from 1 (since the total area under the curve is 1) to get the area to the left of z:
1 - 0.08 = 0.92
Using the standard normal distribution table, we can find the z-value that corresponds to an area of 0.92 to the left of z. This value is approximately 1.41.
(b) Following the same process, for an area of 0.025 to the right of z, we find:
1 - 0.025 = 0.975
Looking at the standard normal distribution table, we find that the z-value corresponding to an area of 0.975 to the left of z is approximately 1.96.
(c) For an area of 0.05 to the right of z, we get:
1 - 0.05 = 0.95

The z-value corresponding to an area of 0.95 to the left of z is approximately 1.64.
(d) Finally, for an area of 0.10 to the right of z, we have:
1 - 0.10 = 0.90
The z-value corresponding to an area of 0.90 to the left of z is approximately 1.28.

Always include the steps and/or background required to get to the final answer. Let’s help other people understand and solve future problems on their own.

Step-by-step explanation:

The solution to the system of equations is x = 4 and y = 5.

3x + 2y = 7

y = 3x - 11

Substitute 3x - 11 for y in the first equation:

3x + 2(3x - 11) = 7

Simplify:

3x + 6x - 22 = 7

Combine like terms:

9x - 22 = 7

Add 22 to both sides:

9x = 29

Divide both sides by 9:

x = 29/9

x = 4

Change x in the second equation to 4:

y = 3(4) - 11

Simplify:

y = 12 - 11

y = 1

The solution to the system of equations is x = 4 and y = 1.

The solution to the system of equations 3x + 2y = 7 and y = 3x - 11 is x = 4 and y = 1. To solve this system, we first substituted 3x - 11 for y in the first equation. We then simplified the equation and combined like terms to get 9x - 22 = 7. We then added 22 to both sides, divided both sides by 9, and got x = 29/9 which is x = 4. We then substituted 4 for x in the second equation, simplified, and got y = 1. Thus, the solution to the system of equations is x = 4 and y = 1.

The zero vector of a null space is the vector that satisfies the equation Ax = 0, where A is a matrix and x is a vector.

In linear algebra, the null space (also called kernel) of a matrix A is the set of all vectors x such that Ax = 0. In other words, it is the set of all solutions to the homogeneous equation Ax = 0.

The zero vector of a null space is the vector that when multiplied by the matrix A results in the zero vector, which means that it is a solution to the homogeneous equation Ax = 0.

Answer:

its  A & B, x<50

Step-by-step explanation:

atmost means till 50.

atleast means more than 50.

The number sentence that states that x is at most 50 is option B: x ≤ 50.

In mathematical notation, the symbol "≤" means "less than or equal to." So, x ≤ 50 translates to "x is less than or equal to 50."

This means that x can be any value that is less than 50 or exactly 50.

Option A (x < 50) would mean "x is less than 50," excluding the value 50 itself.

Option C (x = 50) would mean "x is equal to 50," but it doesn't include any values less than 50.

Option D (x > 50) would mean "x is greater than 50," excluding the value 50 itself.

Option E (x ≥ 50) would mean "x is greater than or equal to 50," which includes values greater than 50, but it doesn't allow any values less than 50.

So, the correct choice to state that x is at most 50 (including the value 50) is option B: x ≤ 50.

P(A and B) = P(A) × P(B) is the formula used to assess if two events are independent (B).

P(A) is the chance that event A will occur.

The chance that event B will occur is marked as P(B).

If the chance of both occurrences happening at the same time, P (A and B), equals the product of the individual probabilities of each event, P(A) x P(B), the events are called independent.

If, on the other hand, the chance of both occurrences occurring simultaneously is less than the product of the individual probabilities of each event, the events are deemed dependent.

Answer:

Step-by-step explanation:

To solve using substitution

3x - 4y = 14

x + y = 7

First solve for y

y = -x + 7

then subsitute 3x - 4(-x-7) = 14

3x + 4x + 28 = 14

7x = 14 - 28

7x = -14

x = -2

Solve for y

-2 + y = -7

y = -7 + 2

y = -5

The simplified expression of the expression  -4y² + 2y + 3y² is  y(-y+2).

To simplify the expression -4y² + 2y + 3y², we combine like terms by adding or subtracting coefficients that have the same variables and the same exponent.

Combining the terms -4y² and 3y², we get:

-4y² + 3y² +2y

-y²+2y

Now let us take the common term y out.

y(-y+2)

So, the simplified expression becomes y(-y+2).

To write a cosine function with amplitude and period, we can use the formula f(x) = A cos (2π / P) x, where A is the amplitude and P is the period.

To write a cosine function with amplitude and period, we can use the following formula:

f(x) = A cos (2π / P) x

where A is the amplitude and P is the period.

The amplitude of a cosine function is the distance from the center line to the maximum or minimum value of the function. It represents the maximum displacement of the function from its mean or average value. The period of a cosine function is the length of one complete cycle of the function. It represents the time it takes for the function to repeat itself.

For example, if we want to write a cosine function with an amplitude of 3 and a period of 4, we can use the formula:

f(x) = 3 cos (2π / 4) x

Simplifying this equation, we get:

f(x) = 3 cos (π / 2) x

The cosine of π/2 is equal to zero, so this equation simplifies further to:

f(x) = 0

This means that the function has a constant value of zero for all values of x.

Answer:

64x+132y= 1040 for the first part

Step-by-step explanation:

z represents the cost of an adult ticket while y represents the cost of a student ticket, so:

64z+132y=$1040

Adults ticket cost twice as much as a students ticket so:

64z=128y

128y+132y=$1040

260y=$1040

y=$4 (Cost of student ticket)

z=$8 (Cost of adult ticket)

First, multiply by 1:

cos x * 1 + cos x tan^2 x

Factor cos x out of cos x tan^2 x

cos x * 1 + cos x (tan ^2 x)

Factor again

cos x (1+ tan^2 x)

Rearrange:

cos x (tan^2 x +1 )

Apply Pythagorean identity:

cos x * sec ^2 x

Rewrite Sec x in terms of sin and cos

cos x * (1 / cos x )^2

Apply product rule:

cos x * 1^2 / cos^2 x

cos x * (1/ cos^2 x )

Cancel common factor cos x

1 / cos x

1/cosx = sec x

The expression that is equivalent to −10.75(20x+15.2) is −215x−163.4.

To see why, we can distribute the -10.75 to the terms inside the parentheses to get -215x - 163.4. This is the equivalent expression. It is important to remember that when you distribute a negative sign, you need to change the signs of all the terms inside the parentheses. None of the other answer choices are equivalent to the given expression. Therefore, the answer is −215x−163.4. It is important to show your work and reasoning to ensure that you are arriving at the correct answer and not making a careless mistake. Additionally, it is always a good practice to double-check your answer by plugging in a value for x and evaluating both expressions to make sure they give the same result.

The length of the river in real life is 600000.

A map's scale is the ratio of a distance on the map to its equivalent distance on the ground. The curvature of the Earth's surface complicates this simple concept by forcing scale to vary across a map. Because of this variation, the concept of scale takes on two distinct meanings.

From the information, the scale on a map is 1 : 300,000 and the length of a river on the map is 2 cm.

In this case, the length on real life will be calculated thus:

Answer:

The probability he rolls a 2 or lower and the coin lands on heads is 16.66%.

Step-by-step explanation:

Since Kane rolls a dice and flips a coin at the same time, to determine what is the probability he rolls a 2 or lower and the coin lands on heads the following calculation must be performed:

Given = 6 sides = 2/6

Coin = 2 sides = 1/2

2/6 x 1/2 = X

0.333 x 0.5 = X

0.1666 = X

0.1666 x 100 = 16.66

Therefore, the probability he rolls a 2 or lower and the coin lands on heads is 16.66%.
