Simplify (4+y) + (8y - 5)

Answer:

Kindly check explanation

Step-by-step explanation:

H0 : π ≥ 0.92

H1 : π < 0.92

At α = 0.05

Left tail

Z0.05/2 = Z0.025 = - 1.645

The test statistic

Zstatistic :

(m - p) / σ

Sample size, n = 85

m = 74/85 = 0.87

p = 0.92

σ = sqrt(p(1 - p) /n)

σ = sqrt(0.92(1 - 0.92) / 85)

σ = sqrt(0.0008658)

σ = 0.0294258

σ = 0.0294

Zstatistic :

(m - p) / σ

(0.87 - 0.92) / 0.0294

Zstatistic = −1.700680

Zstatistic = - 1.70

Decision region :

Reject H0: if ;

Zstatistic < Zcritical

-1.70 < - 1.645

Since,

Zstatistic < Zcritical ; then Reject H0.

Answer:

  sometimes

Step-by-step explanation:

For positive numbers, multiplying by a factor greater than 1 increases their value:

  (1/2) × 2 = 1 > 1/2

For negative numbers, multiplying by a factor greater than 1 decreases their value:

  (-1//2) × 2 = -1 < -1/2

So, "sometimes" the product will be less than the given fraction.

Answer:

-30n+42

Step-by-step explanation:

You have to use distributive property.

Multiply 6 with -5n which is -30n. Then, Multiply 6 with 7 which is 42. Since, 5n is negative the product is also negative, and since 7 is positive the product is positive. Therefore you will get, -30n+42.

I hope this helps!

The simplified form of 6(-5n + 7) is -30n + 42.

To simplify the expression 6(-5n + 7), we apply the distributive property. The distributive property states that when we multiply a number outside the parentheses by an expression inside the parentheses, we must multiply it by each term inside the parentheses.

In this case, we have 6 multiplied by the expression (-5n + 7).

Multiplying 6 by -5n gives us -30n, and multiplying 6 by 7 gives us 42.

So, combining these results, we get -30n + 42.

This simplified expression, -30n + 42, cannot be further simplified because there are no like terms to combine.

Therefore, 6(-5n + 7) simplifies to -30n + 42.

Answer:

this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Only move the negative exponents.

¯\_(ツ)_/¯

Answer:

Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator. It’s a way to change division problems into multiplication problems.

Step-by-step explanation:

A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.

Answer:

4(s+3)

Step-by-step explanation:

If you distribute 4 among the parentheses, it will be equal to s+s+s+s+12.

4(s+3)=4s+12=s+s+s+s+12

Answer:

256

Step-by-step explanation:

16 x 16=256

Answer:

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

Slope = m  & y-intercept = b

x - 5y = 15

   -5y = -x + 15

      y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]

[tex]y = \frac{1}{5}x - 3[/tex]

so, slope = 1/5   ; (-5 , 7)

y -y1 = m(x -x1)

[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

Answer:

(5,53°) or (5,53.13010235°) if you want an exact value.

Step-by-step explanation:

Polar coordinate is in [tex]\displaystyle{(r,\theta)}[/tex] form and rectangular coordinate is in [tex]\displaystyle{(x,y)}[/tex] form.

To convert from rectangular coordinate to polar coordinate, you’ll have to know that:

[tex]\displaystyle{x=r\cos \theta}\\\displaystyle{y=r\sin \theta}[/tex]

Above is crucial when it comes to converting from rectangular coordinate to polar coordinate, or other way around. The thing is to convert from rectangular to polar, you’ll also have to know radius too which you can find by:

[tex]\displaystyle{r=\sqrt{x^2+y^2}}[/tex]

We know that x = 3 and y = 4, substitute in the formula:

[tex]\displaystyle{r=\sqrt{3^2+4^2}}\\\\\displaystyle{r=\sqrt{9+16}}\\\\\displaystyle{r=\sqrt{25}}\\\\\displaystyle{r=5}[/tex]

We know that radius is 5. We will have to find the theta next, first substitute in the conversion:

[tex]\displaystyle{3=5\cos \theta}\\\displaystyle{4=5\sin \theta}[/tex]

Since this can generally be found through calculator as it’s not a part of special triangle - can be found using hand method - The approximation of both theta’s values are 53°.

Hence, the polar coordinate is (5,53°) or (5,53.13010235°) if you want an exact value.
