Answer: The area is 5x + 20

Step-by-step explanation:

Add all the numbers up.

7 + 4x - 8 = 3

13 + (x + 8) = (x + 21)

Therefore, your answer is 5x + 20

Answer:

Option B

Step-by-step explanation:

In this question , we just need to make "F" as the subject of the equation.

So, lets solve the equation.

[tex]R = \frac{F}{N + F}[/tex]

→ Multiplying (N + F) on both the sides ,

[tex]=> R \times (N + F) = \frac{F}{(N + F)} \times (N + F)[/tex]

[tex]=> RN + RF = F[/tex]

→ Substracting both the sides with RF ,

[tex]=> RN + RF - RF = F - RF[/tex]

[tex]=> RN = F - RF[/tex]

→ Taking F common from R.H.S ,

[tex]=> RN = F(1 - R)[/tex]

→ Dividing both the sides by (1 - R) ,

[tex]=> \frac{RN}{1 - R} = \frac{F(1 - R)}{(1 - R)}[/tex]

[tex]=> \frac{RN}{1 - R} = F[/tex]

∴ Hence , [tex]F = \frac{RN}{1 - R}[/tex]

Answer:  [tex](-\infty, 7)[/tex]

You can write this as (-infinity, 7) if you aren't able to use the infinity symbol.

====================================================

Explanation:

Think of x < 7 as writing [tex]-\infty < x < 7[/tex]

So x is between negative infinity and 7, excluding both endpoints.

To write [tex]-\infty < x < 7[/tex] in interval notation, we write [tex](-\infty, 7)[/tex]

The curved parenthesis tell us to exclude the endpoint.

Step-by-step explanation:

Since if it's 5 or higher you go up but if it's 4 or lower you stay the same. And since 2.36 doesn't have the .5 it would round to 2

Answer:

2

Step-by-step explanation:

The rounding rule is 5 or higher round up and below 5 round down. So we're rounding to the nearest whole numbers so we have to look at the tenths place. Since the tenths place number is below 5 we round down to 2.

Answer:

may be 5 I'm not a 100%sure

Answer:

300

Step-by-step explanation:

2 : 3

120/2=60

1 part = 60

(60 x 2) + (60 x 3) = 300 total

There is a total of 300 beans in the jar mung.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

We have been given a jar of mung beans and lima beans in a ratio of 2 : 3, and 120 of the beans are mung beans.

So, 2 : 3

1 part, 120/2 = 60

The total beans in the jar,

(60 x 2) + (60 x 3) = 300

Hence, there is total of 300 beans in the jar.

Answer:

The 95% of confidence interval are

(15.8663 ,16.2337)

Step-by-step explanation:

Step(i):-

Size of the Population = 16

Size of the sample (n) = 4

The mean of the sample = 16.05 oz

The standard deviation of the sample (S) = 0.1 oz

Degrees of freedom =n-1 =4-1 =3

t₀.₀₅,₃  = 3.1824

Step(ii):-

The 95% of confidence interval is determined by

[tex](x^{-} - Z_{0.05} \frac{S}{\sqrt{n} } , x^{-} -+Z_{0.05} \frac{S}{\sqrt{n} })[/tex]

[tex](16.05 - 3.1824\frac{0.1}{\sqrt{3} } , 16.05 -+3.1824 \frac{0.1}{\sqrt{3} })[/tex]

(16.05 -  0.1837 ,16.05  +0.1837 )

(15.8663 ,16.2337)

Final answer:-

The 95% of confidence interval are

A (-2,-2)  → A¹(  -2, 2)

B (-5,-2)  →B¹ (-5 , 2)

C (-3,-4) →C¹ ( -3 ,4))

c)

( x, y) → (  y, -x)

Given (x, y) is rotation 90° of  clock wise about the origin then the transformed to

C (-3,-4) →C¹ ( -4 ,3))

Answer:

The number of faces in 4 faced dice is 4 and in 6 faced dice is 6

therefore, Total possibilities for getting anything is 1/10

The probability of an incorrect conclusion is,

In 84 % of inspection,  [tex]7.56\%[/tex]  of them labeled as not defective but they are actually defective

It is given that,

A quality assurance check is 91% accurate for non-defective devices and 97% accurate for defective devices.

Of the devices checked, 84% are not defective.

Actual not defective is,

            [tex]\frac{91*84}{100} = 76.44\%[/tex]

In  [tex]84\%[/tex] of inspection,[tex]76.44\%[/tex] are actually not defective

Answer:

378.33 minutes

Step-by-step explanation:

From the question, we're told that

Length of the side of the square, l = 4 m

Then the current volume of water = (4 m)³ = 64 m³3 = 64,000 Liters

64,000 + [∫(20 - t) dt from 0 to t] = 0, solving the integral, we have

20t - (t^2)/2 = -64,000, multiplying all by 2 so as to eliminate the fraction

40t - t^2 + 128,000 = 0

t^2 - 40t - 128,000 = 0, on solving the quadratic equation(using general formula), we find that

t = 378.33 minutes

Answer:

E. Assuming that the mean amount of grass eaten by cows is equal to the mean amount of grass eaten by horses, the probability of observing a test statistic of at least 1.664 is 0.0487

Step-by-step explanation:

Given that :

Test statistic, t = 1.064

P-value = 0.0487

Hypothesis : To test if grazing cows eat more grass than grazing horses

The null hypothesis will be :

H0 : μ1=μ2 (that is there is no difference on the mean number of grass eaten by cows and horses).

Alternative hypothesis ; H1 : μ1 > μ2

The null is assumed true unless tested otherwise, the P-value is used as a probability metric for the rejection or acceptance of the null.

Therefore, if the null is True in this scenario, then, the probability of observing a test statistic of at least 1.664 is 0.0487

If the null is true in this scenario, then the probability of observing a test statistic of at least 1.664 is 0.0487.

In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

Test statistics, t = 1.064

P-value = 0.0487

The null hypothesis will be

H₀: μ₁ = μ₂ (There is no difference in the mean number of grass eaten by cows and horses)

An alternative hypothesis will be

Hₐ: μ₁ > μ₂

The null is assumed true unless tested otherwise, the P-value is used as a probability metric for the rejection or acceptance of the null.

Therefore, if the null is true in this scenario, then the probability of observing a test statistic of at least 1.664 is 0.0487.
