Answer:

A. milliliters B. 8 fluid ounces

Step-by-step explanation:

An eyedropper is very small and can only hold a small amount. You can eliminate 2 from the start: millimeter and meter. These two are use for measuring distance not volume. ex.) I walked 2 meters. A liter is too big for an eyedropper. ex.) 1 liter of soda.

A glass full of juice would be 8 fuild ounces because a glass is basically a cup. A 8 gallons is too big, and a 8 tablespoons is too small. ex.) gallon of milk and tablespoon of sugar. 8 cups is too big because a glass is about 1 cup. 8 fluid ounces = 1 cup

Answer:

Slope = -4

x intercept = 3

Step-by-step explanation:

See attachment for graph

Required

a. Determine the slope

b. Find the x intercept and explain what it represents

a. The slope

To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.

$(x_1,y_1) = (3,0)$

$(x_2,y_2) = (0,12)$

Next, we calculate the slope (m)

$m = \frac{y_1 - y_2}{x_1 - x_2}$

$m = \frac{0 - 12}{3 - 0}$

$m = \frac{- 12}{3}$

$m = -4$

b. The x intercept

This is the point where $y = 0.$

From the graph.

$x = 3$ when $y = 0$

This implies that:

After 3 hours, the distance left to cover is 0miles.

In other words, she arrived home in 3 hours

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation is 5.5 days. What length o

Vaselesa [24]

Answer:

A gestation length of 279 days represents the 18th percentile.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation is 5.5 days.

This means that $\mu = 284, \sigma = 5.5$
