The sun of the interior angle measures of a convex polygon is 900° how many sides does it have?
The sum of interiror angle is 900 degree.
The sum of interior angles of polygon is,
\((n-2)\times180\)Here, n is number of sides.
Determine the number of side for sum of interior angle is 900.
\(\begin{gathered} 900=(n-2)\cdot180 \\ \frac{900}{180}=n-2 \\ 5=n-2 \\ n=5+2 \\ =7 \end{gathered}\)So polygon has 7 sides.

Gabriella rented a bike from Jaidee's Bikes. It cost $14 plus $6 per hour. If Gabriella paid $26 total then how many hours did she rent the bike for?
Answer:
2 Hours
Step-by-step explanation:
14+6+6 = 26.
You start with 14, and add on 6 which gives you your starting total 20. So that's one hour. then you add another hour, adding on another $6 making the total $26 and two hours of renting time.

Three of five baseketball players scored more than 10 points. What percent of the players scored more than 10 points?
60 percent of the players scored more than 10 points if three of the five basketball players scored more than 10 points.
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Three of the five basketball players scored more than 10 points.
Total number of basketball players = 5
The number of players who scored more than 10 points = 3
In fraction:
= 3/5
= 0.6
To convert the above fraction into the percentage multiply it by 100:
= 0.6x100
The percent of the players scored more than 10 points = 60%
Thus, 60 percent of the players scored more than 10 points if three of the five basketball players scored more than 10 points.

Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below. 900 + 900(1.015 • 2) What is the correct amount Vince will pay back altogether? Explain the error in Vince's expression. A. 00:00 $903; Vince should have subtracted the first 900 from the amount he will pay. B. 00:00 $913.50; Vince multiplied by the wrong number of years. C. 00:00 $927; Vince wrote the wrong number to represent the interest rate. D. 00:00 $1,813.50; Vince forgot to add the initial $900 to the amount he will pay.
Answer: C. 00:00 $927; Vince wrote the wrong number to represent the interest rate.
Step-by-step explanation:
Given that:
Amount borrowed (p) = 900
Simple interest (r) = 1.5% = 0.015
Time (t) = 2 years
Amount he'll pay back (A) :
A = P(1 + rt)
A = 900(1 + 0.015(2))
A = 900(1 + 0.03)
A = 900(1.03)
A = $927
the quadratic $x^2-3x 1$ can be written in the form $(x b)^2 c$, where $b$ and $c$ are constants. what is $b c$?
The value of b = -3/2 and c = -5/4
To write the quadratic x² - 3x + 1 in the form (x + b)² + c, we can expand (x + b)² and compare it to the given expression:
(x + b)² = x² + 2bx + b²
Comparing this to the given expression x² - 3x + 1, we see that we need:
2bx = -3x, so b = -3/2
b² + c = 1, so substituting b = -3/2 gives:
(9/4) + c = 1
so c = 1 - 9/4
= 4/4 - 9/4
= -5/4
The quadratic x² - 3x + 1 can be written in the form (x - 3/2)² + ( - 5/4).
Therefore, the value of b = -3/2 and c = -5/4

The pie chart represents the results when 120 people in a shopping centre were asked which country they were born in.
57uk 66 germany 105 france 75 ireland 57 other
What fraction of people were born in France?
Give your answer in its simplest form.
The simplified fraction is 7/24.
7/24 of the people surveyed were born in France.
To find the fraction of people born in France, we need to calculate the ratio of the number of people born in France to the total number of people surveyed.
The total number of people surveyed is the sum of the values in the pie chart: 57 (UK) + 66 (Germany) + 105 (France) + 75 (Ireland) + 57 (Other) = 360.
The number of people born in France is given as 105.
Therefore, the fraction of people born in France is 105/360.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 15:
105/15 = 7/1
360/15 = 24/1
So, the simplified fraction is 7/24.
Therefore, approximately 7/24 of the people surveyed were born in France.

assume that t is a linear transformation. find the standard matrix of t. t: , (,), and (,), and (,), where , , and are the columns of the 33 identity matrix.
The standard matrix of the linear transformation t is:
⎡ 1 0 0 ⎤
⎢ 0 1 0 ⎥
⎣ 0 0 1 ⎦
To find the standard matrix of the linear transformation t, we need to determine how the transformation t acts on the standard basis vectors.
The standard basis vectors in ℝ³ are:
e₁ = (1, 0, 0)
e₂ = (0, 1, 0)
e₃ = (0, 0, 1)
We apply the transformation t to each of these vectors:
t(e₁) = t(1, 0, 0) = (t₁₁, t₂₁, t₃₁)
t(e₂) = t(0, 1, 0) = (t₁₂, t₂₂, t₃₂)
t(e₃) = t(0, 0, 1) = (t₁₃, t₂₃, t₃₃)
Therefore, the standard matrix of the transformation t is:
⎡ t₁₁ t₁₂ t₁₃ ⎤
⎢ t₂₁ t₂₂ t₂₃ ⎥
⎣ t₃₁ t₃₂ t₃₃ ⎦
From the information given, we know that the columns of the standard matrix correspond to the images of the standard basis vectors under the transformation t. Using the columns provided in the question:
Column 1: (t₁₁, t₂₁, t₃₁) = (1, 0, 0) = e₁
Column 2: (t₁₂, t₂₂, t₃₂) = (0, 1, 0) = e₂
Column 3: (t₁₃, t₂₃, t₃₃) = (0, 0, 1) = e₃
Therefore, the standard matrix of the linear transformation t is:

Find a vector equation and parametric equations for the line segment that joins p to q. p(1, −1, 7), q(7, 6, 1) vector equation r(t) = <1+6t,−1+7t,7−6t> parametric equations (x(t), y(t), z(t)) =
Vector equation: r(t) = <1, -1, 7> + t<6, 7, -6>
Parametric equations:
x(t) = 1 + 6t
y(t) = -1 + 7t
z(t) = 7 - 6t
The vector equation and parametric equations describe the line segment that joins the two points p and q.
The vector equation is given by r(t) = <1, -1, 7> + t<6, 7, -6>
Here, <1, -1, 7> is the vector that represents the point p, and <6, 7, -6> is the direction vector of the line segment.
The variable t is a scalar parameter that describes the position of any point on the line segment.
The parametric equations are x(t) = 1 + 6t, y(t) = -1 + 7t, z(t) = 7 - 6t.
These equations express the coordinates of any point on the line segment in terms of the parameter t. So we can substitute any value of t between 0 to 1 in this equation to get the coordinates of a point on the line segment.
For example, if we substitute t = 0, we get x(0) = 1, y(0) = -1, z(0) = 7
which gives us the coordinates of point p.
Similarly, if we substitute t = 1, we get x(1) = 7, y(1) = 6, z(1) = 1
which gives us the coordinates of point q.
So, the line segment is defined by the set of all points whose coordinates are given by these equations for values of t between 0 and 1.

It is important to note that the p-value does not directly represent the probability of making a mistake in the test. The p-value depends on the chosen significance level and the specific context of the hypothesis test.
There seems to be an incomplete sentence in your question. However, based on the information you provided, I can explain the concept of the p-value in hypothesis testing.
In hypothesis testing, the p-value is the probability of observing a test statistic as extreme as, or more extreme than, the one calculated from the sample data, assuming that the null hypothesis is true. It is a measure of the strength of evidence against the null hypothesis.
A p-value of 0.32 means that if the null hypothesis is true, there is a 0.32 probability of obtaining a test statistic as extreme as, or more extreme than, the one observed in the sample data.
Typically, in hypothesis testing, a significance level (α) is chosen before conducting the test. If the p-value is less than or equal to the significance level, usually 0.05, then the null hypothesis is rejected in favor of the alternative hypothesis. If the p-value is greater than the significance level, the null hypothesis is not rejected.
It is important to note that the p-value does not directly represent the probability of making a mistake in the test. The interpretation of the p-value depends on the chosen significance level and the specific context of the hypothesis test.
