which fraction is equal to 0.5 7
The value of fraction 0.5 7 is equal to 1/2.
We are given that;
Number = 0.57
Now,
There are different ways to express a fraction as a decimal, but one common method is to divide the numerator by the denominator.
For example, 1/2 as a decimal is 1 ÷ 2 = 0.512.
Another method is to use a fraction to decimal conversion chart or calculator345. According to these sources, 0.5 as a fraction is equal to 5/10 or 1/2.
These fractions are equivalent because they have the same value when simplified or reduced.
To simplify a fraction, we can divide both the numerator and the denominator by their greatest common factor (GCF).
Therefore, by algebra the answer will be 1/2.

Line a through (2, 3) is parallel to line b with equation y = -1, which point below a lso lies on line a? A (2,9) B(-5, 3) C (0, 1) D (1, 4)
Answer:
B (-5, 3)
Step-by-step explanation:
The line a passes through point ( 2,3 ).
Line b has equation y= -1
Plot the graph for line b, y=-1 , which is a horizontal line as shown in the attached graph
Plot point (2, 3) and draw the graph of line a, y=3 to form a line a parallel to line b
You will notice that point B (-5, 3) is the one the lies on line a.
The answer option A,(2,9) is incorrect because it does not lie on any of the lines
The answer option C (0, 1) is incorrect because it lies along the y-axis
The answer option D (1, 4) is incorrect because it does not lie on any of the lines.
Solve for x
O 10°
O 189
O 20°
O 22.5°
Answer:
[tex]\boxed{x=10}[/tex]
Step-by-step explanation:
We are given two angles, which together, have a sum of 90°. We call these complementary angles. The angle ∠EAF is the complement of angle ∠FAB and vice versa.
Therefore, because they sum up to be 90°, we can simply add the angles together and solve for x this way.
[tex]4x+5x=90\\\\9x = 90\\\\\frac{9x}{9} = \frac{90}{9}\\\\\boxed{x = 10}[/tex]
The variable x equals 10. We can go even further to check and verify that this is correct by substituting our original value for x into the equation.
[tex]4(10)+5(10)=90\\\\40 + 50 = 90\\\\90 = 90[/tex]
90 does in fact equal 90, so your final answer is x = 10°.
Hope this helps! :)
Which number line expression shows how to find the distance from 2 to -5?
Answer:
5+2=7
Step-by-step explanation:
put -3, 1 3/4, -0.5 and 3 least to greatest to least.
Answer:
-3, -0.5, 1 3/4, 3
Step-by-step explanation: in a number line negative is always less than positive so the bigger the negative number the more is goes down on the number line so that's why -3 is smaller then -0.5 because -0.5 is closer to positive than -3
QUESTION 1 Let’s say that an investigator is interested in the effects of caring for a person with ALS (Lou Gehrig’s disease) on physical and mental health. In particular, the researcher wants to know whether ALS caregivers suffer from clinically elevated levels of depression. They administer the Beck Depression Inventory (BDI) to 20 ALS caregivers. Scores on the BDI range from zero to 40. Scores at or above 25 are considered to reflect clinically significant levels of depression. The mean depression score for the 20 caregivers in the sample is 28. The standard deviation for this sample is 3.0. Do these data support the hypothesis that the mean depression score for ALS caregivers is significantly higher than the cutoff score for depression of 25? This example is not a perfect example of a "true experiment," so the independent and dependent variable are not as clearly identifiable as some other examples. In this example, what is the dependent/outcome variable? Beck Depression Inventory scores How many ALS caregivers there are in the study Whether the caregivers are taking care of someone who has ALS vs. cancer The ALS caregivers vs. the national norms for adults
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the data support the hypothesis that the mean depression score for ALS caregivers is significantly higher than the cutoff score for depression of 25
dependent/outcome variable
Generally the dependent variable is Beck Depression Inventory (BDI) scores because the score are dependent on the ALS caregivers
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The population mean is [tex]\mu = 25[/tex]
The sample mean is [tex]\= x = 28[/tex]
The standard deviation is [tex] s = 3.0[/tex]
The null hypothesis is [tex]H_o : \mu = 25[/tex]
The alternative hypothesis is [tex]H_a : \mu > 25[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x - \mu }{ \frac{s}{\sqrt{n} } }[/tex]
=> [tex]z= \frac{ 28 -25 }{ \frac{3.0}{\sqrt{20 } } }[/tex]
=> [tex]z= 4.47[/tex]
Generally the probability of z from the z- table is
[tex]p-value = P(Z > 4.47) = 0.000[/tex]
From the values obtained we see that [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the data support the hypothesis that the mean depression score for ALS caregivers is significantly higher than the cutoff score for depression of 25
Generally the dependent variable is Beck Depression Inventory (BDI) scores because the score are dependent on the ALS caregivers

Answer: k=3
Step-by-step explanation:
To solve for k, you want to isolate k.
[tex]\frac{2}{5} (5k+35)-8=12[/tex] [add both sides by 8]
[tex]\frac{2}{5} (5k+35)=20[/tex] [multiply both sides by 5/2]
[tex]5k+35=50[/tex] [subtract both sides by 35]
[tex]5k=15[/tex] [divide both sides by 5]
[tex]k=3[/tex]
Now, we know that k=3.

20 is 1000 times of 0.02. Correct answer is option C.
What is Decimal ?Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.
Here, given value
0.02 = 002/100
= 2/100
On multiply numerator and denominator by 10, we get
0.02 = 20/1000
or 20 = 1000 X 0.02
Thus, 20 is 1000 times of 0.02.

Determine the intercepts of the line
X-intercept: (__ , __)
Y-intercept: (__, __)
Answer:
x-intercept: (-40, 0)
y-intercept: (0, 15)
Step-by-step explanation:
The x-intercept is the value of x when y = 0. By looking at the graph, you can tell when y = 0, x = - 40. The x-intercept is the point that crosses the x-axis.
The y-intercept is the value of y when x = 0. By looking at the graph, you can tell y = 15 when x =0. The y-intercept is the point that crosses the y-axis.

The sum of three consecutive odd integers is -75. What is the smallest number
Answer:
-27
Step-by-step explanation:
First, let's call the smallest number: n
Then, the next two consecutive odd numbers would be:
n+2 and n+4 (this is because it's only odd numbers so we add 2)
We know the sum of these is −75 so we can write this equation and solve for n:
n + (n + 2) + (n + 4) = -75
n + n + 2 + n + 4 = -75
n + n + n + 2 + 4 = -75
n + n + n + 6 = -75
1n + 1n + 1n + 6 = -75
3n + 6 = -75 Subtract 6 from each side, which cancels the 6 on the left.
3n + 6 - 6 = -75 - 6
3n = -75 - 6
3n = -81 Divide each side by 3
3n/3 = -81/3
n = -81/3
n = -27
n + 2 = -27 + 2 = -25
n + 4 = -27 + 4 = -23
The 3 consecutive odd integers would be:
-27, -25, -23
Let's check our work:
-27 + -25 + -23 = -75 We are correct!
The smallest number is -27
