Answer:

330 hs

Step-by-step explanation:

If Alice sleeps an average of 9 hs and her cat sleeps an average of 20 hours each day we can say that her cat sleeps an average of 11 hours more per day than her.

If the cat sleeps 11 hours more than her per day, for getting the hours he sleeps more by month we just need to multiply the daily value by the number of days in a month. Thus,

30 * (11) = 330

So, her cat sleeps an average of 330 hours more than her in a month, which can be decomposed in 11 hours a day.

I hope it is understandable.

The total area of the polygon is 176 square feet. Find the value of x.
My name is Ann [436]

Answer:

x = 6 ft

Step-by-step explanation:

Total area of the given polygon = Area of triangle 1 + Area of rectangle 2 + Area of triangle 3

Area of triangle 1 = Area of triangle 3 = \frac{1}{2}(\text{Base})(\text{Height})

                                                              = \frac{1}{2}(x)(8)

                                                              = 4x square feet

Area of rectangle 2 = Length × Width

                                 = 16 × 8

                                 = 128 square feet

Total area of the given polygon = 4x + 128 + 4x

176 = 8x + 128

8x = 176 - 128

x = \frac{48}{8}

x = 6 ft

ACME Manufacturing claims that its cell phone batteries last more than 32 hours on average in a certain type of cell phone. Test
son4ous [18]

Answer:

We can conclude that the battery life is greater than the 32 hour claim.

Step-by-step explanation:

The null hypothesis is:

H_{0} = 32

The alternate hypotesis is:

H_{1} > 32

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}

In which X is the statistic, \mu is the mean, \sigma is the standard deviation and n is the size of the sample.

In this problem, we have that:

X = 37.8, \mu = 32, \sigma = 10, n = 18

So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{37.8 - 32}{\frac{10}{\sqrt{18}}}

t = 2.46

We need to find the probability of finding a mean time greater than 37.8. If it is 5% of smaller(alpha = 0.05.), we can conclude that the battery life is greater than the 32 hour claim.

Probability of finding a mean time greater than 37.8

1 subtracted by the pvalue of z = t = 2.46.

z = 2.46 has a pvalue of 0.9931

1 - 0.9931 = 0.0069 < 0.05

So we can conclude that the battery life is greater than the 32 hour claim.

A slide has an angle of elevation of 25°. It is 60 feet from the end of the slide to the stairway beneath the top of the slide.
Valentin [98]
Cos 25=0.90631
cos 25=(the end of the slide to the stairway beneath the top of the slide)/( length of the slide)
length of the slide=60/0.90631=66.2
the length of the slide = 66.2 feet
