Answer:

[tex]f(0)=7[/tex]

Step-by-step explanation:

[tex]f(0)[/tex] is the value of [tex]f(x)[/tex] when [tex]x=0[/tex]. Therefore, to find [tex]f(0)[/tex], we need to substitute [tex]x=0[/tex] into [tex]f(x)[/tex], or [tex]3x+7[/tex]. Thus, [tex]f(0)=3*0+7=0+7=7[/tex]. Hope this helps!

Answer:

1.06x

Step-by-step explanation:

The original price of a carrot cake is represented by x.

Emily increased the price of carrot cakes at her bakery by 6%.

We need to find an expression that represents the price of a carrot cake after the increase.

Price = x+6% of x

[tex]=x+\dfrac{6}{100}x\\\\=x+0.06x\\\\=1.06x[/tex]

Hence, the required equation is "1.06x".

Answer:

[tex]n = \frac{7}{m + 2} [/tex]

Step-by-step explanation:

[tex]m + 2 = \frac{7}{n} [/tex]

To make n as the subject , we need to isolate it.

■ Lets multiply n on both the sides in order to shift n to the L.H.S.

[tex] = > n(m + 2) = \frac{7}{n} \times n[/tex]

[tex] = > n(m + 2) = 7[/tex]

■ Lets now divide (m + 2) on both the sides in order to isolate n in L.H.S

[tex] = > \frac{n(m + 2)}{( m+ 2)} = \frac{7}{(m + 2)} [/tex]

[tex] = > n = \frac{7}{m + 2} [/tex]

Answer:

The number of judges that should be selected  is 25

Step-by-step explanation:

Given that:

The C.I = 90%

Level of significance = 1 - C.I

= 1 - 0.90

= 0.10

Critical level for [tex]Z_{\alpha/2}[/tex] at 0.10 = 1.645

The margin of error E = 2.00

Let's assume that the sample standard deviation was $6.11

Then;

The number of judges that should be selected can be computed by using the formula:

[tex]E = Z_{\alpha/2} \times \dfrac{s}{\sqrt{n}}[/tex]

[tex]2 = 1.645 \times \dfrac{6.11}{\sqrt{n}}[/tex]

[tex]2\sqrt{n} = 10.05095[/tex]

[tex]\sqrt{n} = \dfrac{10.05095}{2}[/tex]

[tex]\sqrt{n} =5.026[/tex]

[tex]n=(5.026)^2[/tex]

n = 25.26

n ≅ 25

Answer:

The sample mean would most likely be 50 centimeters.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

The mean of the population is 50 centimers.

So, by the Central Limit Theorem, the sample mean would most likely be also 50 centimeters.

Answer:

Tracey paid 34.5% of the original price.

Explanation

Tracey paid $190 for an item that was originally priced at $550.

For finding the percentage, first we need to divide the paid amount by the original price and then multiply the result by 100%

So, the percentage 190/500 x 100 % = 34.5% (Rounded to the nearest tenth)

3 pounds because strawberries cost $3.00 per pound.What is cost? A cost is the worth of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting. In the case of an acquisition cost, the money spent on the acquisition is considered the cost.What connection exists between price and quality?Regardless matter whether the relationship is positive [higher costs are linked with higher quality] or negative [higher quality is associated with lower costs], the majority of research have concluded that the relationship between cost and quality is minimal to moderate.Given: Cost of Strawberries per pound = $3. 00a. How many pounds of strawberries can you buy for $1.00?Answer: 0 because the cost of per pound strawberries is $3.00So, he can not but any pound at $1.00but he can but 1/4 pound as the cost given b.

Answer:

negative they are 4 negative factors

The product of the expression would be Negative; there are four negative factors.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have a multiplication expression with eight rational factors.

It is given that Half of the factors are positive and half are negative.

For an integer, the factor is the decomposition of that integer in terms of smaller integers; when multiplied with each other gives back that considered number. Those composing integers are known as factors that considered integers.

Answer:

C) g(x) =  |x+4|+2

The new function  g(x) =  |x+4|+2

Step-by-step explanation:

Given that the parent function f(x) = |x|

The function shifts '4' units left then the function transformed to

g(x) = |x+4|

Again the function shift '2' units up then the function transformed to

g(x) = |x+4|+2

Final answer:-

The new function g(x) =  |x+4|+2

Step-by-step explanation:

We know that the formula to a right triangle is a^2 + b^2 = c^2

so assume 73 and 55 are both Not the hypotenuse, then

73*73 + 55*55 = c^2

5329 + 3025 = 8354

c = 91.4
