Divide x^3+2 by x+1 long division ppleeease! :)

1 answer:

3 0

Long division: (x³ + 2) ÷ (x + 1)

 x² – x + 1 
x³ + 0x² + 0x + 2 | x + 1
– x³ – x² ⋮ ⋮
– x² + 0x ⋮
+ x² + x ⋮
+ x + 2
 – x – 1
+ 1

 Quotient: Q(x) = x² – x – 1;

Remainder: R(x) = + 1.

I hope this helps. =)

Suppose that a restaurant chain claims that its bottles of ketchup contain 24 ounces of ketchup on average, with a standard devi

Tanya [424]

Answer:

Confidence Interval = (23.776, 24.224)

Step-by-step explanation:

Restaurant chain claims that its bottles of ketchup contain 24 ounces of ketchup on average.

⇒ Mean = 24 ounces.

Standard Deviation = 0.8

Number of bottles used for sample = 49

⇒ n = 49

Confidence level = 95%

Corresponding z value with 95% confidence level = 1.96

Now, confidence interval is given by the following expression :

$Mean \pm z^*\times \frac{\sigma}{\sqrt{n}}\\\\=24\pm1.96\times \frac{0.8}{\sqrt{49}}\\\\=24\pm 0.224$

Hence, Confidence Interval = (23.776, 24.224)

Plz help me with this

$\bold{\text{Answer:\qquad }b)\quad \bigg(\dfrac{1}{2},-2\bigg)}$

Step-by-step explanation:

The vertex form of an absolute value equation is: $f(x)=|x-h|+k$ where

(h, k) is the vertex. In the given equation, $f(x)=\bigg|x-\dfrac{1}{2}\bigg|-2$ , the h-value is 1/2 and the k-value is -2.

So, the vertex (h, k) = (1/2, -2)

Reduce any fractions to lowest terms.Don’t round your answer, and don’t use mixed fractions

DENIUS [597]

Answer:

t < $\frac{38}{17}$

Step-by-step explanation:

Add '5t' to both sides

12t - 2 +5t < -5t +36 +5t

17t -2 < 36

Add ' 2' to both sides

17t -2 +2 < 36 + 2

17t < 38

Dividing '17' on both sides

$\frac{17t}{17}$ < $\frac{38}{17}$

Consider a normal distribution curve where 90-th percentile is at 20 and the 25-th percentile is at 10. use this information to

ivann1987 [24]

The 25th percentile corresponds to z ≈ -0.67.
The 90th percentile corresponds to z ≈ 1.28.
So, you can write two equations in μ and σ as here:
.. μ -0.67σ = 10
.. μ +1.28σ = 20

The solution is
.. μ ≈ 13.45
.. σ ≈ 5.11
