...What is, -7=z/2+1
Answer:
z=-16
Step-by-step explanation:
-7 = (z/2) + 1 Original equation
-7-1 = (z/2) Combining like terms
-8 = z/2 Simplification
-8 × 2 = (z/2) × 2 Isolating the variable
-16 = z The answer
Check your answer
-7 = (-16/2) + 1 Substitution
-7= -8 + 1 Simplify
-7 = -7 Your answer is right

Answer:
D. 9 mm³Step-by-step explanation:
Given
Dimension of the prism: 3x4x6Side of each small cube: 1/2 mmVolume of the prism in terms of the number of small cubes:
3*4*6 = 72Volume of each unit cube:
V = (1/2)³ = 1/8 mm³Volume of the prism:
72*1/8 = 9 mm³Correct choice is D
Answer:
D. 9 mm³
Step-by-step explanation:
Dimension of the prism
= 3 * 4* 6
side of each small cube
= 1/2 mm
In terms of number of small cubes , volume of the prism = 3 *4 * 6= 72
Volume of each unit of cube
= (1/2)³
= 1/ 8 mm³
Volume of the prism
= 72 * 1/8
= 9 mm³

A bicycle path starts 5 miles due east of an intersection, and continues in a straight line to finish 8 miles due north of the same intersection. Let the intersection be represented by the point (0, 0). Suppose a cyclist rides the path from start to finish in 2 hours. Which parametric equations model the path of the rider?
The parametric equations that models the path of the rider are:
x(t) = -5/2t + 5 and y (t)= 4tx(t) = -5/2t + 5 and y(t) = 4t + 8What is a Parametric Equation?This refers to the type of equation that makes use of a parameter to define dependent variables.
Hence, we can see that to model the path of the rider, the parametric equation that can be best used is to model the direction of the bicycle which is moving 5 miles east and then continues 8 miles north, and the fact that they started at rest 0 and the equations to make the model are:
x(t) = -5/2t + 5 and y (t)= 4tx(t) = -5/2t + 5 and y(t) = 4t + 8

A researcher for a polling organization used a random sample of 1,540 residents in a city to construct a 95 percent confidence interval for the proportion of voters who would vote for candidate Jones. The resulting confidence interval was 0.480 ± 0.025. What is the correct interpretation of the confidence interval?
A proportion of 0.455 and 0.505 of respondents think that Jones has a 95% chance to win.
If 95% of all the voters voted, then Jones would receive between 45.5% and 50.5% of the votes.
The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.
If we repeatedly sampled voters from this city, taking samples of size 1,540, approximately 95% of those samples would have between 45.5% and 50.5% voting for Jones.
Answer:
The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.
Step-by-step explanation:
took the quiz
The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.
What is confidence interval?A confidence interval is a set of values used to estimate an unknown population parameter with a high degree of certainty. It is calculated from a sample of data and takes into account the sample's variability.
The polling organisation is 95% confident that the range of 0.455 to 0.505 accurately represents the proportion of all city voters who would vote for Jones.
This means that if the researcher repeated the sampling process a number of times and created a confidence interval for each sample, 95% of those intervals would contain the true proportion of all city voters who would vote for Jones.
Thus, it does not imply that the true proportion is 95% likely to fall within the interval.

A one-question survey is to be distributed to a random sample of 1500 adults in Ohio. The question asks if they support an increase in the state sales tax from 5% to 6%, with the additional revenue going to education. Let p-hat denote the proportion of adults in the sample who say they support the increase. Suppose that 40% of all adults in Ohio support the increase. What is the probability that p-hat will be more than 50%
Solution :
It is given that :
Total number of adults in the sample of Ohio, n = 1500
Increase in the sale tax = 5% to 6 %
Let [tex]$\hat p$[/tex] = proportion of the adults that supported the increase in the sales tax.
= 40%
= 0.40
Therefore the probability that [tex]$\hat p$[/tex] will be more than 50% will be :
[tex]$P(\hat p > 0.50) = P\left( \frac{\hat p - E(\hat p)}{\sigma_{\hat p}} > \frac{0.50-0.40}{0.0123}\right)$[/tex]

Answer:
No, because grabbing the math book changed the odds of grabbing the notebook.
These are not independent events as you didn't replace the first book so that changed the probability that you would draw a notebook second , Option C is the answer.
What is Probability ?Probability is the likeliness of an event to happen.
It is given that there are three math books, two science books, and five notebooks.
Total number of books = 3 + 2 + 5 = 10
The probability of drawing a mathbook is 3 / 10 = 0.3

Don’t use for points or will be reported and I’ll take the points back
Answer:
X=151
Step-by-step explanation:
1. 61+90= 151
-Combine the two given angles
2.180-151= 29
-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.
-29 is your difference which is also the angle next to X.
3.180-29= 151
-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.
-Therefore X=151
Mental health in America. In the Mental Health Surveillance Study, clinicians interviewed a very large random sample of American adults so as to diagnose the presence of mental disorders in the prior 12 months. There are many types of mental disorders, and a person can suffer from more than one. Let X represent the number of mental disorders a person has experienced in the past year. Based on this study, we can assign the following probability distribution to X in the American adult population:
X 0 1 2 3 4 or more
P(X) 0.775 0.149 0.041 0.022 0.013
(a) Explain why this is a valid probability distribution. Is the sample space discrete orcontinuous?
(b) Find P(X <2) and P(1≤X≤3).
(c) Obtain the probability that a randomly selected American adult suffers from
(i) at least one mental disorder
(ii) either one or two mental disorders
Answer:
a) It is a valid distribution because the sum of all possible probabilities is 1. The sample space is discrete, because the number of diseases is a countable number.
b) P(X <2) = 0.924, P(1≤X≤3) = 0.212
c - i) 0.225
c - ii) 0.19
Step-by-step explanation:
(a) Explain why this is a valid probability distribution. Is the sample space discrete or continuous?
0.775 + 0.149 + 0.041 + 0.022 + 0.013 = 1
Since the sum of all possible probabilities is 1, this is a valid probability distribution.
Since the possible outcomes are 0, 1, 2, 3 or 4 diseases, that is, countable numbers, the sample space is discrete.
(b) Find P(X <2) and P(1≤X≤3).
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.775 + 0.149 = 0.924[/tex]
[tex]P(1 \geq X \geq 3) = P(X = 1) + P(X = 2) + P(X = 3) = 0.149 + 0.041 + 0.022 = 0.212[/tex]
(c) Obtain the probability that a randomly selected American adult suffers from
(i) at least one mental disorder
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.775 = 0.225[/tex]
(ii) either one or two mental disorders
[tex]P(X = 1) + P(X = 2) = 0.149 + 0.041 = 0.19[/tex]
