A swimming pool is being filled at the rate of 15

What is the slope of (1,2) (-3,-9)

kati45 [8]

Answer:

(11/4) is the slope

Step-by-step explanation:

1) Subtract the second y value (-9) by the first y value (2) in the coordinates. This equals 11.

2) Then, subtract the second x value (-3) by the first x value (1) in the coordinates. This equals 4.

3) Divide the answer you get for step one by the answer for step 2 and that's your slope. 11/4

Dave is comparing the circumferences of several trees in his yard. The oak tree is 0.539 meters in circumference, the ash tree h

stepan [7]

Answer: c. elm

Step-by-step explanation:

Given : The circumference of the oak tree= 0.539 meters

= $0.539\times100=53.9\text{ cm}$ [∵ 1 m = 100 cm] (1)

The circumference of the ash tree= 0.509 yards

$=0.509\times3\text{ feet}$ [∵ 1 yard = 3 feet]

$=0.509\times3\times 30.48\text{ cm}$ [∵ 1 foot = 30.48 cm]

$=46.54296\approx46.54\text{ cm}$ (2)

The circumference of the elm tree = 6281.70 millimeters

$=\dfrac{6281.70}{10}=628.17\text{ cm}$ (3)

The circumference of the poplar tree = 0.000385 miles

$=0.000385 \times5280\text{ feet}$ [∵ 1 mile = 5280 feet]

$=0.000385 \times5280\times30.48\text{ feet}$ [∵ 1 foot = 30.48 cm]

$=61.959744\approx61.96\ \text{ cm}$ (4)

From (1) , (2) , (3 ) and (4) it is clear that

46.54< 53.9 < 61.96 < 628.17

Hence, the elm tree has the greatest circumference.

Ok she would have to buy 5 personal trainers to be equal the same with the other gym.

Gym 1 is $25 ( $25, $50, $75, $100)

Suppose you take a simple random sample of size n=175 from the population of Reese's Pieces, still assuming that 45% of this pop

Gnesinka [82]

Answer:

The probability is $P(0.35$

Step-by-step explanation:

From the question we are told that

The sample size is n = 175

The population proportion is p = 0.45

Generally the mean of the sampling distribution is $\mu_{x} = 0.45$

Generally the standard deviation is mathematically represented as

$\sigma_{x} = \sqrt{\frac{p (1-p)}{n} }$

=> $\sigma_{x} = \sqrt{\frac{0.45 (1-0.45)}{175} }$

=> $\sigma_{x} = 0.0376$

Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is

$P(0.35 < X < 0.55) = P( \frac{0.35 - 0.45}{0.0376} < \frac{X -\mu_{x}}{\sigma_{x}} < \frac{0.55 - 0.45}{0.0376} )$

=> $P(0.35$

Generally $\frac{X - \mu_{x}}{\sigma_{x}} = Z (The \ standardized \ value \ of X)$

So

$P(0.35$

=> $P(0.35$

From the z-table

$P( Z< 2.6595 ) = 0.99609$

and

$P( Z< - 2.6595 ) = 0.0039128$

So

$P(0.35$

=> $P(0.35$
