be used if 2 cups of strawberries are used?

You should use 1 cup of yogurt because 11/2 divided by 3 is 1/2 so if only 2 cups out of three are being used then you would use 1 cup of yogurt.

After allowing 20% discount on the marked price with 13%

saveliy_v [14]

<u>Answer:</u>

The marked price of the article is 22,600

<u>Explanation: </u>

Given, selling price of an article SP = Rs. 18080

To calculate marked price MP, the formula used is

$\mathrm{SP}=\mathrm{MP}\left(1-\frac{D \%}{100}\right)$

Discount D = 20%

Substituting the given values

SP = $\mathrm{MP}\left(1-\frac{20}{100}\right)$

18080 = $\mathrm{MP}\left(1-\frac{1}{5}\right)$

$18080=\mathrm{MP}\left(\frac{4}{5}\right)$

$\mathrm{MP}=\frac{18080 \times 5}{4}$

MP = Rs. 22,600

Therefore the marked price of the article is 22,600

Answer: a. A point estimate for p is 0.597 .

b. The 95% confidence interval for p.

Lower limit = 0.48

Upper limit = 0.71

Step-by-step explanation:

Given : Sample size of professional actors : n= 67

Number of extroverts : x= 40

Let p represent the proportion of all actors who are extroverts.

a. The point estimate for p = sample proportion = $\hat{p}=\dfrac{x}{n}$

$=\dfrac{40}{67}=0.597$

b. Confidence interval for population proportion :

$\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

Since the critical value for 95% confidence interval is 1.96 , so the 95% confidence interval for p would be

$0.597\pm (1.96)\sqrt{\dfrac{0.597(1-0.597)}{67}}$

$0.597\pm (1.96)\sqrt{0.0036}$

$0.597\pm (1.96)(0.06)$

$0.597\pm 0.1176$

$(0.597-0.1176,\ 0.597+0.1176)\\\\=(0.4794,\ 0.7146)\\\\\approx(0.48,\ 0.71)$

In the 95% confidence interval for p.

Lower limit = 0.48

Upper limit = 0.71

What is the distance between the following points?

timama [110]

Answer:

D. d = $\sqrt{58}$

Step-by-step explanation:

Use the distance formula: d = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2} }$

The two points are (6, -2) and (3, -9)

Plug the values into the formula:

d = $\sqrt{(3 - 6)^{2}+ (-9 + 2)^{2} }$

Simplify

d = $\sqrt{(-3)^{2}+ (-7)^{2} }$

d = $\sqrt{9+ 49 }$

d = $\sqrt{58}$

I hope this helps :))
