2 x + 5 = 10 what is x =?

Mathematics

MrMuchimi3 years ago

Answer:

x=\frac{5}{2}

Step-by-step explanation:

First, subtract 5 on both sides since when you subtract 5 from 5, it will give you 0.

Basically we are trying to get rid of the +5.

2x+5-5=10-5

2x=5

Divide by 2 to get rid of the 2 that is combined with the x.

2x/2=5/2

x=\frac{5}{2}

Answer:x=5/2

Step-by-step explanation:

2x+5=10

Subtract 5 from both sides

2x+5-5=10-5

2x=5

Divide both sides by 2

2x/2=5/2

x=5/2

Solnce55 [7]

Answer:

d. (16/24) * 100%

Step-by-step explanation:

The infection rate =( Number of infected people/ total number of people) *  100%

After the end of round 3

Infection rate = (8/24)*100%

After the end of round 4, since no one is infected more than once

Infection rate = 2* (8/24)*100%

Infection rate = (16/24) * 100%

Mini staw<br> D:<br> R:<br> what is the domain and range
IgorC [24]

The entire range of independent variable values is the domain of a function.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

What is domain and range?

  • The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain.
  • The range is the set of y-values that are produced when all the conceivable x-values are substituted.

The entire range of independent variable values is the domain of a function.

Keep these things in mind when locating the domain:

  1. A fraction's denominator (bottom) cannot be 0.
  2. In this section, the integer following a square root symbol must be positive.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

The variety of potential y-values makes up a function's range (minimum y-value to maximum y-value)

  1. To observe what happens, substitute several x-values into the expression for y.
  2. Be sure to search for the least and highest y values.

Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit
aalyn [17]

Answer:

Step-by-step explanation:

The type I error occurs when the researchers rejects the null hypothesis when it is actually true.

The type II error occurs when the researchers fails to reject the null hypothesis when it is not true.

Null hypothesis: The proportion of people who write with their left hand is equal to 0.23: p =0.23

Type I error would be: Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29

Since 0.29 is assumed to be the alternative claim.

Type II error would be: Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29

Still with the assumption that 0.29 is the alternative claim.
