To find the height of the cactus, make a ratio.

58 inches divided by 4 feet equals x inches divided by 8 feet.

58/4 = x/8

14.5 = x/8

116 = x

The height of the cactus is 116 inches.

marishachu [46]

Answer:

Option 2) Null hypothesis: p = 0.078 , Alternate hypothesis: p > 0.078

Step-by-step explanation:

We are given the following in the question:

According to the National Center of Health Statistics, about 7.8% of all babies born in the U.S. are categorized as low birth weight.

Sample size, n = 1200

p = 7.8% = 0.078

We have to carry a hypothesis test whether national percentage is higher than 7.8% or not.

Thus, we can design the null and the alternate hypothesis

H_{0}: p = 0.078\H_A: p > 0.078

Thus, the correct answer is:

Option 2) Null hypothesis: p = 0.078 , Alternate hypothesis: p > 0.078

Answer:

C. 7790.83 cm^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the radius is 12.3

Using 3.14 for pi  (This will give us an approximation, not an exact value)

V = 4/3(3.14) (12.3)^3

   =7790.82984 cm^3

Alchen [17]

Answer:

630,630 different arrangements are possible for the given laptops.

Step-by-step explanation:

Total number of laptops = n = 15

Number of identical Dell laptops  = 6

Number of identical Chromebooks  = 4

Number of identical Mackbooks = 5

We have to find in how many ways can the laptops be arranged. Number of arrangement of objects is calculated using Permutations as the order of objects matter during the arrangement. The formula to calculate the number of possible arrangements when there are similar objects is given as:

\frac{n!}{a!b!c!...}

Here n is the total number of objects and a,b, and c represent the number of identical objects. Using the given values we get:

\frac{15!}{6!4!5!} = 630630

This means 630,630 different arrangements are possible for the given laptops.
