Answer:

I believe the answer is 84 centimeters.

Step-by-step explanation:

If the wheel is 5.6 centimeters in diameter, the car is traveling 5.6 centimeters per spin of the wheels. Therefore, you do the equation, 5.6 * 15 and get 84.

Answer: there's no solution

Step-by-step explanation:

first, we remove the parenthesis.

-12x + 3 = -12x - 18

then, we cancel equal terms.

3 = -18

that doesn't work, so it makes a false statement.

no solution.

Answer:

Just substitute

Step-by-step explanation:

Given:

[tex]\dfrac{1+\sin \theta}{\cos \theta}+\dfrac{\cos \theta}{1+\sin \theta}=2\sec \theta [/tex]

To prove:

The given statement.

Proof:

We have,

[tex]\dfrac{1+\sin \theta}{\cos \theta}+\dfrac{\cos \theta}{1+\sin \theta}=2\sec \theta[/tex]

Taking LHS, we get

[tex]\text{LHS}=\dfrac{1+\sin \theta}{\cos \theta}+\dfrac{\cos \theta}{1+\sin \theta}[/tex]

Taking LCM, we get

[tex]\text{LHS}=\dfrac{(1+\sin \theta)^2+cos^2\theta }{\cos \theta(1+\sin \theta)}[/tex]

[tex]\text{LHS}=\dfrac{(1)^2+2\sin \theta +\sin^2 \theta+cos^2\theta }{\cos \theta(1+\sin \theta)}[/tex]    [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]

[tex]\text{LHS}=\dfrac{1+2\sin \theta +1}{\cos \theta(1+\sin \theta)}[/tex]    [tex][\because \sin^2 \theta+cos^2\theta =1][/tex]

[tex]\text{LHS}=\dfrac{2+2\sin \theta}{\cos \theta(1+\sin \theta)}[/tex]

[tex]\text{LHS}=\dfrac{2(1+\sin \theta)}{\cos \theta(1+\sin \theta)}[/tex]

[tex]\text{LHS}=\dfrac{2}{\cos \theta}[/tex]

[tex]\text{LHS}=2\sec \theta[/tex]         [tex][\because \sec\theta=\dfrac{1}{\cos \theta}][/tex]

[tex]\text{LHS}=\text{RHS}[/tex]

Hence proved.

Answer:

Here,

f(x)=2x+3(x-3)

if f(x)=11

we know that,

or,11=2x+3(x-3)

or,11=2x+3x-9

or,11+9=5x

or,20=5x

Therefore,x=4

Answer:

x = 4

Step-by-step explanation:

2x + 3x - 9 = 11

5x = 11+9

5x = 20

x = 4

Answer:

1 ; 1.25 ; 0.25 ; - 0.75 ; - 1.25 ;- 0.5

Step-by-step explanation:

Given the sample observations : 15, 16, 12, 8, 6, 9

Zscore for each sample Observation :

Zscore = (x - mean) / standard deviation

(15 + 16 + 12 + 8 + 6 + 9) / 6 = 11

Mean value (m) = 11

Standard deviation (s) = 5

Sqrt[(x - m)^2 / (n - 1)]

[(15-11)^2 + (16-11)^2 + (12-11)^2 + (8-11)^2 + (6-11)^2 + (9-11)^2] / (6 - 1)

= 80/5 = 16

Sqrt(16) = 4

Zscore = (x - mean) / standard deviation

x = 15

Zscore = (15 - 11) / 4 = 1

x = 16

Zscore = (16 - 11) / 4 = 1.25

x = 12

Zscore = (12 - 11) / 4 = 0.25

x = 8

Zscore = (8 - 11) / 4 = - 0.75

x = 6

Zscore = (6 - 11) / 4 = - 1.25

x = 9

Zscore = (9 - 11) / 4 = - 0.5

Statistics.

Step-by-step explanation:

Statistics is the branch of exact sciences that has the objective of collecting data from reality from taking samples of a specific group of society or a particular situation, thing or event, and comparing the differences between these samples to obtain a general sample of a certain common characteristic.

Thus, statistics seeks through comparison to establish parameters on which the other sciences are based in order to develop theories, relying on the repetition of characteristics common to the groups analyzed.

Answer: the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05

Step-by-step explanation:

Given that;

X has normal distribution has mean µ = 3

standard deviation σ = 2  

now

P( x< 4) = P( (x-µ)/σ /(3-4)/5)

= P( z < -0.5 )

= 0.3085  {from the z-table}

X has binomial distribution with n = 8 and p = 0.3085

so P(x=5)

P(x=5) = 8C₅(0.3085)⁵ (1 - 0.3085)⁸⁻⁵

= 0.0517  ≈ 0.05

Therefore the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05

Answer:

0.99998412723

Step-by-step explanation:

basically i divided 252 by 252.004 and got 0.99998412723 so 252.004 times 0.99998412723 equals 252

I hope this helps!

Answer:

no,

Step-by-step explanation:

The reason for this is because if you were to take away the 4 at the end of both 0's you could easily just multiply by 1 but due to the 4, you can multiply anything to get 252

Answer:

The Chi-square test of independence

Step-by-step explanation:

The answer to this question is the Chi-square test of independence because it is what is used to determine the existence of an association between nominal/categorical variables. This test is non parametric in nature and it can also be called the chi square test of association.

The data is tabulated. each row is a representation of the category for one of the variables and each column is for the other variable.

i got it right on my quiz

By looking at the table, we can see that the value for g(x) is always f(x)-1. Thus we can conclude that

[tex]g(x) = 4^x-1[/tex]

Now, think about the graph. For every value of y in f(x), the value of y in g(x) will be reduced by one. This means that the graph is translated down 1 unit!

The domain of both functions is actualy the same, that is, [tex]x\in\mathbb{R}[/tex].

However, the range won't be the same. As [tex]x[/tex] approaches negative infinity, the exponentials always approaches zero. Thus, f(x) has range between zero and positive infinity. But, for g(x), we are subtracting one unit from the Y values, therefore the range will be between negative one and positive infinity. In conclusion, their range is different.

Overral: The true statements are the second and the fourth only

Answer:5.25

Step-by-step explanation:

3(1/7 + 1/x) = 1

3([x + 7]/7x) = 1

3x + 21 = 7x

4x = 21

x = 21/4 OR 5.25

It will take wendy 5.25hrs to clean the house by herself.

In order to get the time it take wendy to clean the house by herself, we will use the expression:

1/a = 1/x + 1/y

1/3 = 1/7 + 1/y

1/y = 1/3 - 1/7

1/y = 7-3/21

1/y = 4/21

y =  21/4

y =  5.25hrs

Hence it will take wendy 5.25hrs to clean the house by herself.

Hi there! :)

[tex]\large\boxed{\text{B. 11 cm.}}[/tex]

Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:

a² + b² = c²

Use the length and width in the equation:

8² + 3² = c²

64 + 9 = c²

73 = c²

c ≈ 8.54 cm

Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:

(8.54)² + 7² = c²

73 + 49 = c²

122 = c²

√122 = c

c = 11.05 ≈ 11 cm. The correct answer is B.

Answer: It's 11.5

Explanation ( took so long)

[tex]C = \sqrt{a^{2} + b^{2} }\\14 = \sqrt{8^{2} + b^{2} }\\14 = \sqrt{64 + b^{2} }\\14^{2} = 64 + b^{2} \\196 = 64 + b^{2} \\64 +b^{2} = 196\\b^{2} = 196 - 64\\b^{2} =132\\b = \sqrt{132} \\b = 11.48[/tex]
