y=2x+2

Answer: g<22.5

Step-by-step explanation:

Isolate the variable by dividing each side by the factor that don’t contain the variable.

2 1/2 +3

pretend that there is a denominator for 3 which is 1

2 1/2 +3/1

find the common denominator for 3/1 which is 2

multiply by 2 for 3/1

3(2)/1(2)=6/2

2 1/2 +6/2

make 2 1/2 into a fraction

multiply 2*2  first

2*2=4

add 4 with the numerator

4+1=5

2 1/2=5/2

5/2+6/2

=11/2

= 5 1/2

answer: 11/2 or 5 1/2

Answer:

Quartic

Step-by-step explanation:

Given

[tex]h(x) = 4x^4 + 2x - 5[/tex]

Required

Name the polynomial

The question required that the polynomial be named based on its degree.

This implies that, we name the polynomial based on the highest power of x

Highest power of x = 4

When the highest power of x in a polynomial is 4, such polynomial is a quartic polynomial.

Hence, by degree; the polynomial is quartic

Answer:

Step-by-step explanation:

Given that:

Sample Mean [tex]\overline x[/tex] = 82.25

The Standard deviation of the population [tex]\sigma[/tex] = 30.00

The Sample size = 100,000

The margin of error M.O.E = 0.186

At a 95% confidence interval level;

[tex]=\overline x - M.O.E < \mu < \overline x + M.O.E[/tex]

= 82.25 - 0.186 < [tex]\mu[/tex] < 82.25 +  0.186

= 82.064 < [tex]\mu[/tex] < 82.436

= (82.064 , 82.436)

The 95% confidence interval of the population mean = (82.064 , 82.436)

Before we can determine the sampling error, we need to find the standard error of the mean.

The standard error of the mean is:

[tex]\mu_ {\bar x} = \mu = 82.25[/tex]

[tex]\sigma_{\bar x} = \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]\sigma_{\bar x} = \dfrac{30}{\sqrt{100000}}[/tex]

[tex]\sigma_{\bar x} = \dfrac{30}{316.23}[/tex]

[tex]\sigma_{\bar x} = 0.096[/tex]

At 95% confidence interval, the level of significance = 1 - 0.95 = 0.05

[tex]Z_{0.05/2} = Z_{0.025}[/tex] = 1.96

Now, the sampling error can be determined by using the formula:

[tex]=Z_{\alpha/2} \times \sigma _{\overline x}[/tex]

[tex]=Z_{0.025} \times \sigma _{\overline x}[/tex]

= 1.96 × 0.096

= 0.18816

Answer:

it will be 12f

Step-by-step explanation:

since you told the wrong question

Answer:

Question 1) Is option C: 2. (Question 2) The correct answer is 1.09 for the K12 program. Question 3) Option A: The value of a motorcycle decreases by 12% each year. (Option C) Every year, the number of online subscribers to a service is 4 times what it was the previous year.

The ratio of outputs for any two inputs that are one value apart is 4 thus option (A) is correct. The ratio of outputs for any two inputs that are two values apart is 1/8. The situation in option (3) represents the exponential function.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given table,

The ratio of outputs for any two inputs that are one value apart = (-1/2)/(-1/8) = 4

The ratio of outputs for any two inputs that are two values apart = (-1/8)/(-1) = 1/8

Every year, the number of online subscribers to a service is 4 times what it was the previous year's exponential function with a 4^x exponent.

Hence "The ratio of outputs for any two inputs that are one value apart is 4. The ratio of outputs for any two inputs that are two values apart is 1/8 and the third statement shows exponential function".

Answer:

Step-by-step explanation:

1.5x + 1.3x = -8.4

2.8x = -8.4

x=-3

As per the provided question, we have to find the value of x. So, we can easily find the value of x by transposition method.

[tex] \sf \red { 1.5x + 1.3x = -8.4 } [/tex]

[tex] \sf {\implies 2.8x = -8.4 } [/tex]

[tex] \sf {\implies x =\dfrac{ -8.4 }{2.8}} [/tex]

[tex] \sf {\implies x =\dfrac{ -84 \times \cancel{10} }{28 \times \cancel{10}}} [/tex]

[tex] \sf {\implies x =\dfrac{ -84 }{28}} [/tex]

[tex] \sf {\implies x = -3} [/tex] [tex] \purple {\bigstar} [/tex]

Just substitute the value of x in L.H.S .

[tex] \sf \red { 1.5x + 1.3x = -8.4 } [/tex]

Therefore

[tex] \sf {\implies 1.5(-3) + 1.3(-3)= -8.4 } [/tex]

[tex] \sf {\implies -4.5+ (-3.9)= -8.4 } [/tex]

[tex] \sf {\implies -4.5-3.9= -8.4 } [/tex]

[tex] \sf \purple {\implies -8.4= -8.4 } [/tex]

[tex] \sf {\therefore L.H.S= R.H.S } [/tex]

75% of the tape diagram is shaded.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The tape diagram.

Let us consider the whole tape as 1 and 100%.

It is  divided into four parts.

3 parts of 4 parts are shaded.

Three divided by four.

3/4=0.75

Now multiply 0.75 with 100.

0.75×100

75%

Hence, 75% is the shaded diagram percentage.

Answer:

A. 14

Step-by-step explanation:

Answer:

60%

Step-by-step explanation:

A percent is technically just a fraction over 100.

To get that here, we simply divide the part (which is 1560 people) by the whole (which is 2600 people) and then multiply that by 100:

(1560 / 2600) * 100 = 0.6 * 100 = 60/100

Thus, we know that the percent is 60%.

Answer:

57/60-52/60

Step-by-step explanation:

First you have to make the denominator the same to subtract. By find out what number they have in common. And the number was 60.  15x4=60  and 20x3=60. And whatever you do to the bottom you do for the top 19x3= 57. 13x4=52. So the form would be 57/60-52/60. Once you find the form then you subtract 57-52=5 and when you minus the denominator it stays the same. so the ANSWER would be 5/60.

Answer:

(32,16)

Step-by-step explanation:

When you dilate a coordinate by a factor say a, the coordinate of the image are multiplied by this factor to get the coordinate of the pre-image. For example, if the coordinate of the image is (x,y) dilated by a factor of "a", the coordinate of the pre-image will be (ax, ay)

Given the coordinate (16, 8) the coordinate of the pre image of dilated by a factor of 2 is given as;

(2×16, 2×8) = (32, 16)

Hence the coordinates for the pre-image Q is (32,16)
