Step-by-step explanation:
Find two easy points on the graph to calculate the slope:
(-2, 0)(0, -2)The slope is calculated using [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], so substitute in the values:
[tex](x_{1}, y_{1}) = (-2, 0)\\(x_{2}, y_{2}) = (0, -2)\\ \frac{y_{2}-y_{1} }{x_{2}-x_{1}} =\frac{(-2)-0}{0-(-2)} =\frac{-2}{0+2} =\frac{-2}{2} =-1[/tex]
The y-intercept is where it intersects the y-axis. It's -2.
Therefore, if you put it together, the function would be y = -x - 2
Solve each answer choices and find the one that matches the function:
B.[tex]y-3=-(x+5)\\y-3=-x-5\\y=-x-5+3\\y=-x-2[/tex]
What is the value of x if x/4+2=15
Help!
Answer:
Step-by-step explanation:
because i don't know if the 2 is with the 4 or not I have calculated both.
x/4 + 2 = 15
<=> x/4 = 13
<=> x = 13.4 = 52
x/(4+2) = 15
<=> x/6 = 15
<=> x = 6.15 = 90
Answer:
52
Step-by-step explanation:
[tex]\frac{x}{4} + 2 = 15[/tex]
The first step is to shift all number values to the right. To do this, subtract 2 from the equation.
This will give
[tex] \frac{x}{4} = 13[/tex]
Now, multiply the equation by 4.
Hence,
[tex]x = 13 \times 4 = 52[/tex]

What is the value of the missing angle (x+15)
Answer:
x = 70
Step-by-step explanation:
The total interior angle in a square, even with not a perfect square, adds to 360
Set your formula up as
360 = (x+15) + x + 115 + 90
360 - 115 - 90 - 15 = 2x
140 = 2x
140/2 = x
70 = x
A food distribution company has employees that order food supplies for local restaurants by predicting sales. The company pulls an SRS of 500 orders and finds that 408 orders were correct. Calculate and interpret a 95% confidence interval for the proportion of all orders that were correct
Answer:
(0.782, 0.85)
Step-by-step explanation:
Here
The sample size = 500
Number of favourable cases = 408
Confidence interval = 95%
Proportion of sample = 408/500 = 0.816
Critical value for alpha = 0.05 is z (1-alpha/2) = 1.96
Confidence interval = p -zc * sqrt (p(1-p)/n), p + zc * sqrt (p(1-p)/n)
Substituting the given values we get –
0.816-1.96 * sqrt (0.816(1-0.816)/500), 0.816+1.96 * sqrt (0.816(1-0.816)/500)
(0.782, 0.85)
The area of a triangle with a height of 9 cm and a base of 6 cm is
Answer:
27 cm²
Step-by-step explanation:
Formula of Area Triangle = 1/2(base x height)
Base = 6 cm
Height = 9 cm
1/2 ( 6 x 9 ) = 1/2 ( 54 ) = 27
Units = cm * cm = cm²
27 cm²
Why the formula (1/2 ( base x height )) works:
Take a triangle
Duplicate the triangle
And rotate the triangle and put it next to the other one
What shape does it form?
Either a parallelogram or a rectangle
The formula for a parallelogram or rectangle is (base x height)
Since you are initially doubling the area of the triangle to get the rectangle, solve for the rectangle and divide by 2.
So, do base x height
And divide by 2

Which of the following expressions is equivalent to the one shown below ?
(-5 • 4)^3
A. (-5)^3•4^3
B. -15^3•12
C. -15•12
D. -8•7
Answer:
Its A
Step-by-step explanation:
You must distribute exponents outside of parentheses to each
A = -5^3 × 4^3
B = multiplies each by 3 then raises 1 to the third, very off
C = just multiplied each by 3
D = very off, added by 3
Seven times the sum of twice a number and 16
Answer:
7(2x+16)
Step-by-step explanation:
first, we look at the part where it says the sum of twice a number and 16
let's represent the number by using x. since it says twice a number, that would mean 2x.
when it says the sum of twice a number and 16, this means that we have to add them, so we would get 2x+16.
finally, in the beginning it says seven times the sum of twice a number and x, which would mean that we would have to multiple 2x+16 by 7.
answer:
7(2x+16)

Solve for x. Show your work. -12x < -12
Step-by-step explanation:
-12x < -12
-12x/-12= x
-12/-12= 1
x < 1
-12x < -12
Divide both sides by -12 and because you are dividing by a negative number you need to reverse the inequality sign.
The answer becomes x > 1

Need help asap please show work
Answer:
m<5= 75° Alternate angles are equal
m<6 = 180°-75°= 105 ° Angles on a straight line adds up to 180°
In a rectangle opposite sides are equal so AB= CD
2x+8= 3x+4
3x-2x=8-4 ( combine like terms, the signs will change since they are going over opposite sides)
x= 4
To solve for BC
AD= BC
x+17 ( we know that x=4)
4+17=21
Therefore BC= 21

Can anyone help pls? Thanks much appreciated
Answer:
x ≈ 5.7
Step-by-step explanation:
Recall, SOH CAH TOA.
We are given:
Reference angle = 35°
Opposite side length to reference angle = 4
Adjacent side = x
To find x, apply the trigonometric equation, TOA, which is:
Tan 35° = Opp/Adj
Substitute
Tan 35° = 4/x
x*Tan 35° = 4
x = 4/Tan 35°
x ≈ 5.7

the graph shows the relationship between the amount of milk and water used in a recipe
Answer:
Multiply the amount of milk by 4
Step-by-step explanation:
Given
See attachment for graph
Required
The rule of the graph
Pick any two points on the graph
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,4)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4 - 0}{1 - 0}[/tex]
[tex]m = \frac{4}{1}[/tex]
[tex]m =4[/tex]
The graph equation is:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 4(x - 0) + 0[/tex]
[tex]y = 4(x)[/tex]
[tex]y = 4x[/tex]
The above shows that the x values are multiplied by 4 to get y
Your neighbor has a bag with 5 oranges and 7 apples in it. You will be receiving two pieces of fruit from your neighbor. What is the probability, in percent, that you will receive 2 apples, assuming she removes them from the bag in random order
Answer:
31.82% probability that you will receive 2 apples.
Step-by-step explanation:
The fruits are removed from the bag, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
5 + 7 = 12 total fruits, which means that [tex]N = 12[/tex]
7 apples, which means that [tex]k = 7[/tex]
You receive 2 fruits, which means that [tex]n = 2[/tex]
What is the probability, in percent, that you will receive 2 apples, assuming she removes them from the bag in random order?
This is, as a proportion, P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,7) = \frac{C_{7,2}*C_{5,0}}{C_{12,2}} = 0.3182[/tex]
0.3182*100% = 31.82%
31.82% probability that you will receive 2 apples.

Yesterday, the temperature et noon was 11.4" misright, the tempe tine had decreed by 15.7 degrees what was the
Temperature at midnight
Answer:
-4.3 degrees
Step-by-step explanation:
if I understand the problem correctly, then the temperature at midnight fell 15.7 degrees from 11.4 degrees at noon.
11.4 - 15.7 = -4.3 degrees
so, the temperature at midnight was -4.3 degrees

Why can the value of the variable a in the expression a + 2 be any number?
Why does the variable b in the equation b + 2 = 5 have only one value?
Please help Without any links or without deleting the answer<3
Answer:
(a) Because the expression is not an equation
(b) Because the expression is an equation
Step-by-step explanation:
Solving (a): a + 2
The above expression can assume any value for a because it is not an equation.
Take for instance:
a = 2;
[tex]a + 2 \to 2 + 2 = 4[/tex]
[tex]a =-4[/tex]
[tex]a + 2 \to -4 + 2 = -2[/tex]
The reason for this is because the expression is not an equation
Solving (b): [tex]b + 2 = 5[/tex]
The above expression can assume only value for b, and the value is:
[tex]b + 2 = 5[/tex]
[tex]b = 5-2[/tex]
[tex]b =3[/tex]
This means that only [tex]b =3[/tex] will make the equation true.
The reason for this is because the expression is an equation
