Step-by-step explanation:

Answer:

f(x) is another way of saying "y", but when x is replaced with a number, it just means that x = that number.

Since A says to find f(7), it means that in this scenario, x = 7. So, 2x - 5 is turned into 2(7) - 5, which equals 14 - 5, which equals 9.

So, f(7) = 9.

You can then apply this to the rest of the numbers you are given.

Answer:

sample mean

Step-by-step explanation:

Using the normal distribution and the central limit theorem, considering that this is a sample proportion, as we are dealing with percentages, it is found that there is a 0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The mean and the standard deviation of the sampling distribution of sample proportions are given by:

[tex]\mu = p = 0.55[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.55(0.45)}{100}} = 0.04975[/tex]

The probability of getting less than 50% Democrats in a random sample of size 100 is the p-value of Z when X = 0.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.5 - 0.55}{0.04975}[/tex]

[tex]Z = -1.01[/tex]

[tex]Z = -1.01[/tex] has a p-value of 0.1562.

0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

The value of z in the given arrangement is 2 m.

Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.

Also,

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.

So, here we will use the concept of similar triangles,

According to the definition the corresponding sides are in proportion.

So, we get,

z/a = b/z

z² = 4

z = 2

Hence, the value of z in the given arrangement is 2 m.

Answer:

-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

xy = 18

x+y = -12

y = -12-x

substitution method:

x(-12-x) = 18

-12x - x² - 18 = 0

-x² - 12x - 18 = 0

-(x² + 12x + 18) = 0

used quadratic formula:

(-12±√144 - 4(18)) ÷ 2

(-12 ± [tex]\sqrt{72}[/tex]) ÷ 2

(-12 ± 6[tex]\sqrt{2}[/tex]) ÷ 2

= -6 ± 3[tex]\sqrt{2}[/tex]

Answer:

10x=y.

Step-by-step explanation:

10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)

Answer:

y = 10x

Step-by-step explanation:

The total earnings, y, is equal to the hourly rate, 10, times x, the hours worked.

y equals 10 times x, or, in equation form, y = 10x.
