Reiko’s goal is to practice the drums for at least 800 minutes per week. This week, Reiko already has practiced for 175 minutes. If she practices for 35 minutes each session, Reiko wants to know how many sessions are left for her to make her goal.
Answer:
18 more sessions
Step-by-step explanation:
Her goal is to practice 800 minutes.
She already did 175 minutes.
That means she has 800 - 175 = 625 minutes remaining, and she says that she will only practice in 35 minute sessions.
To determine the number of sessions she has left, just divide 625 by 35.
[tex]\frac{625}{35}[/tex]
= 17.85714
However, you can't have a portion of a session, as she only does 35 mins every session. Therfore, she must do 18 more sessions.

Find the value of x.
48°
126°
Answer:
78°
Step-by-step explanation:
angle on a straight line : 180° - 126° = 54°
Therefore, 48° + 54° = 102°
total angle in a triangle = 180°
So, 180° - 102° = 78°

Step-by-step explanation:
The daily temperatures in fall and winter months in Virginia have a mean of 62o F. A meteorologist in southwest Virginia believes the mean temperature is colder in this area. The meteorologist takes a random sample of 30 daily temperatures from the fall and winter months over the last five years in southwest Virginia. The mean temperature for the sample is 59oF with a standard deviation of 6.21oF. Do the data provide convincing evidence at the Alpha = 0.05 level that the mean temperature in fall and winter months in southwest Virginia is less than 62o F?
What is the test statistic for this significance test?
z = 2.65
t = 2.65
z = –2.65
The correct test statistic for this hypothesis test is t = -2.88, not z = -2.65 or z = 2.65.
To perform a hypothesis test, we start by stating the alternative hypotheses:
H0: μ = 62 (the population temperature is 62 degrees F)
Ha: μ < 62 (the population temperature is less than 62 degrees F)
X is the sample temperature, μ is the population temperature, s is the sample standard deviation, and n is the sample size.
Plugging in the values, we get:
t = (59 - 62) / (6.21 / √(30)) = -2.88
Finally, we compare the test statistic to the critical value from the t-distribution with n - 1 f and an alpha level of 0.05. Since the alternative hypothesis is one-tailed (μ < 62), we use a one-tailed test and look up the critical value for a t-distribution with 29 f and an alpha level of 0.05. The critical value is -1.699.
Since the test statistic of -2.88 is smaller than the critical value of -1.699, we reject the null hypothesis and conclude that there is convincing evidence at the alpha = 0.05 level that the temperature in fall and winter months in southwest is less than 62 degrees F.

Answer: 260(0.962)^8
Step-by-step explanation:
Pretty simple. We have a base of 260, which all of the answers include. Then for a decay rate of 3.8, we reduce to percentage form ( 0.038 ) and subtract that from 1 ( or 100 in standard form ).

Y=4
Y= 1/2 x
Y = 2x + 3
Y = -3/2 x -1
The equation that represents a proportional relationship
[tex]\[Y = \frac{1}{2}x\][/tex]
In a proportional relationship, the dependent variable (Y) is directly proportional to the independent variable (x). This means that as x increases or decreases, Y changes in a consistent ratio or fraction. In this equation, the ratio or fraction is [tex]\(\frac{1}{2}\)[/tex], indicating that for every unit increase in x, Y increases by [tex]\(\frac{1}{2}\)[/tex] units.
Let's break down the equation:
[tex]\(Y\)[/tex] represents the dependent variable, and it varies linearly with respect to the independent variable [tex]\(x\).[/tex]
The equation states that the value of Y is equal to [tex]\(\frac{1}{2}\)[/tex] times the value of [tex]\(x\).[/tex]
For example, if we have [tex]\(x = 4\)[/tex], we can substitute it into the equation to find the corresponding value of Y:
[tex]\[Y = \frac{1}{2}(4) = 2\][/tex]
So, when [tex]\(x\)[/tex] is 4, [tex]\(Y\)[/tex] is 2. This satisfies the proportional relationship because the ratio [tex]\(\frac{Y}{x}\)[/tex] remains constant at [tex]\(\frac{1}{2}\).[/tex]
Similarly, if we have [tex]\(x = -6\)[/tex], we can substitute it into the equation:
[tex]\[Y = \frac{1}{2}(-6) = -3\][/tex]
Therefore, when [tex]\(x\)[/tex] is -6, [tex]\(Y\)[/tex] is -3. Again, the ratio [tex]\(\frac{Y}{x}\)[/tex] remains constant at [tex]\(\frac{1}{2}\)[/tex].
Hence, the equation [tex]\(Y = \frac{1}{2}x\)[/tex] represents a proportional relationship where Y is directly proportional to x with a constant ratio of [tex]\(\frac{1}{2}\)[/tex].

Enter the number that belongs in the green box
The required length is 11 units for the given triangle.
The sine rule defines the side length ratios of triangles to their opposing angles. This proportion is true for all three sides and opposing angles.
a/sinA = b/sinB = c/sinC
The triangle is given in the question, as follows:
In ΔABC, ∠A=120°, ∠B=37°, and c = 5 units
Here, ∠C= 180° - 120° - 37° = 23.
We have to determine the length of a.
As per the sine rule, the required solution would be as:
a/sin∠A = c/sin∠C
Substitute the known values and we get
a/sin 120° = 5/sin 23°
a = (18/sin 1240°) × sin 23°
k ≈ 11
