How to find the steeper slope in a graph?

Sauron [17]

Answer:

When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, . The greater the slope, the steeper the line.

your class of 32 students is divided into fourths to create groups to answer a set of questions together then 1/4 of each group

Alecsey [184]

Answer:

2 students

Step-by-step explanation:

32 students are divided into fourths:

32/4 = 8

Each group has 8 people.

1/4 of the students in each group is the same as dividing 8 into fourths:

8/4 = 2

2 students from each group will go up to the front of the classroom.

Hope this helps :)

Can anyone answer this please? I need help

BARSIC [14]

Answer:

84 cm squared, 30 cm squared, 18 cm squared

Step-by-step explanation:

Formula for triangle area= 1/2 Base * Height

Area for triangle ABD= 1/2 (12cm)*(14cm)

=84 cm squared

Area for triangle BC(orange triangle)= 1/2 (6cm)*(10cm)

=30 cm squared

BC= half of BD

Area for triangle CD(Green triangle)= 1/2 (6cm)*(4cm)

=12 cm squared

n automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally di

Paraphin [41]

Answer:

0.3557 = 35.57% probability that one selected subcomponent is longer than 118 cm.

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 116 cm and a standard deviation of 5.4 cm.

This means that $\mu = 116, \sigma = 5.4$

Find the probability that one selected subcomponent is longer than 118 cm.

This is 1 subtracted by the pvalue of Z when X = 118. So

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

$Z = \frac{118 - 116}{5.4}$

$Z = 0.37$

$Z = 0.37$ has a pvalue of 0.6443

1 - 0.6443 = 0.3557

0.3557 = 35.57% probability that one selected subcomponent is longer than 118 cm.
