THREE QUESTIONS WILL GIVE BRAINLIEST

1 answer:

8 0

1. Answer: To create graphs from verbal expressions, first you have to write the verbal expression as a function. Then, you can create a table of values to look for a pattern and graph the function. The key features of any function can be compared in tables and graphs by creating the matching graph for the function.

2. It is because there is no value of x that will cause the value of f(x) in the formula to equal 0. Notice that the graph crosses the y-axis at 1. ... The inverse of an exponential function is a logarithmic function and the inverse of a logarithmic function is an exponential function

3. y = e^x is an exponential function that increases gradually from (-∞, 0) until it reaches the point (0,1). Thereafter, it very sharply increases on (0,∞).

Hey Can you help me with my questions? I need help for English... and Math!?

X(4x-3)=0 <br> A. {-3/4, 0} <br> B. {3/4,0} <br> C.{3/4}

svet-max [94.6K]

Answer:

B. {3/4,0}

Step-by-step explanation:

$x(4x - 3) = 0 \\ x = 0 \: \: or \: \: 4x - 3 = 0 \\ x = 0 \: \: or \: \: x = \frac{3}{4} \\ x = \bigg\{ \frac{3}{4}, \: \: 0 \bigg\}$

Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 mont

Zigmanuir [339]

Answer and explanation:

Given : Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 months with a standard deviation of 2 months. The records show that the sentence lengths are normally distributed.

i.e. Mean $\mu=26$ , Standard deviation $\sigma=2$

Using Z-score formula,

$Z=\frac{\bar{x}-\mu}{\sigma}$

1) What is the Z score for a 23 month sentence length? What is the probability of getting a sentence below that?

The Z score value for a $\bar{x}=23$ is given by,

$Z=\frac{23-26}{2}$

$Z=\frac{-3}{2}$

$Z=-1.5$

The probability of getting a sentence below that is $P(X$

i.e. $P(X$

$P(X$

2) A defense attorney is concerned that his client's sentence was unusually harsh at 30 months. What percent of sentences are 30 months or longer? Calculate the Z score and report the area.

The Z score value for a $\bar{x}=30$ is given by,
