Answer:

mBAD = 244°

Step-by-step explanation:

~ Let us calculate the two unknown angles, represented by two lines each. These two lines are shared by each angle such that they are congruent ~

m∠ APE = x = m∠ EPD,

360 - 136 = m∠ APE + m∠ EPD + 42 + 74,

224 = x + x + 42 + 74,

224 = 2x + 116,

2x = 108,

x = 54 = m∠ APE = m∠ EPD

Now that we know the measure of these unknown angles, let us solve for the degree measure of arc BAD, as such:

mBAD = m∠ BPA + m∠ APE + m∠ EPD,

mBAD = 136 + 54 + 54,

mBAD = 244°

Answer: option B is the correct answer

Step-by-step explanation:

Candace's backyard has a flower garden that covers 40% of her backyard.

If the total area of her backyard is 450 square feet, it means that her garden covers 40% of 450 square feet.

To determine how many square feet is her flower garden, we will find the value of 40% of 450 square feet. It becomes

40/100 × 450= 0.4×460 = 180 square feet

Debora [2.8K]

Answer:

$0.1546\leq \widehat{p}\leq 0.3513$

Step-by-step explanation:

The firm tests 75 parts, and finds that 0.25 of them are notusable

n = 75

x = 0.25 \times 75 = 18.75≈19

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{19}{75}$

$\widehat{p}=0.253$

Confidence level = 95%

So, Z_\alpha at 95% = 1.96

Formula of confidence interval of one sample proportion:

$=\widehat{p}-Z_\alpha \sqrt{\frac{\widehat{p}(1-\widehat{p}}{n}}\leq \widehat{p}\leq \widehat{p}+Z_\alpha \sqrt{\frac{\widehat{p}(1-\widehat{p}}{n}}$

$=0.253-(1.96)\sqrt{\frac{0.253(1-0.253)}{75}}\leq \widehat{p}\leq0.253+(1.96)\sqrt{\frac{0.253(1-0.253}{75}}$

Confidence interval $=0.1546\leq \widehat{p}\leq 0.3513$

This is number 8. And I need help.

It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p

Hope this helps! Good luck!
