Volume of this child development center=long x width x deep.
we expressed all magnitudes (long, width and deep) in yards.
Data:
long=125 ft=125 ft * (1/3 yd/ft)=125/3 yd
width=60 ft=60 ft * (1/3 yd/ft)=20 yd
deep=6 in * (1 yd / 36 in)=1/6 yd

We calculate the volume:
volume=(125/3 yd)*(20 yd)*(1/6 yd)=138.8888....yd³≈139 yd³

Answer: 139 yd³

The maximum speed an animal can walk in feet per second is a 5.7VI, where l is the animal's leg length in feet. What is the maxi
ad-work [718]

Answer:

Maximum walking speed of camel is  31.749V feet per second

Step-by-step explanation:

Walking speed of an animal is given by :

Speed = 5.7VI (in feet per second) where l is the animal's leg length.

For a camel, leg length is 5.7feet.

So maximum walking speed of camel will be:

Speed of camel = 5.7V * 5.7 = 5.7² V feet per second

Speed of camel = 31.749V feet per second

hence, maximum walking speed of camel is  31.749V feet per second

Bogdan [553]

Answer:

a) -1.25

b) 0.2112

c) -1.96

Step-by-step explanation:

Data provided in the question:

Sample size, n = 400

H0 : p = 20

\bar{p} = 175

Now,

a) The test statistic is  given as:

Z = \frac{(\bar{p}-p)}{\sqrt{\frac{p(1-p)}{n}}}

on substituting the respective values, we get

Z = \frac{(0.175-0.2)}{\sqrt{\frac{0.2\times0.8}{400}}}

= -1.25

b) The p-value = 2 × P(Z <-1.25)

Now from the standard normal table

P(Z <-1.25) = 10.56% = 0.1056

Thus,

p-value = 2 × 1056 = 0.2112

c) for a = 0.05,

the critical value is Z_{\frac{a}{2}}=Z_{\frac{0.05}{2}} i.e Z_{0.025}

Now from standard normal table

Z_{0.025} = -1.96
