Answer:
x = 109°
Step-by-step explanation:
Utilise the fact that angles in a triangle add up to 180 so,
→ Form an equation
x + 23 + 48 = 180
→ Simplify
x + 71 = 180
→ Minus 72 from both sides to isolate x
x = 109°
Answer:
109°
Step-by-step explanation:
x+48+23=180
x=180-71
x=109°6171819

A trumpet player is currently standing in position (3, 2) on a gridded football field. Her bandleader
instructs her to move two units to the left and one unit up. What are her new coordinates?
The trumpet player's new coordinates are
Answer:
(1, 3)
Step-by-step explanation:
Current position (3,2)
Moving left of the x axis results in a decrease, so: 3 - 2 (As she is moving 2 units to the left)
Moving up results in a positive increase on the y axis, so: 2 + 1 (As she is moving one unit up)

Given the figure below, find the values of x and z.
Answer: x = 2 and z=78
Step-by-step explanation:
Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.
Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:
5x + 92 + 78 = 180
5x + 170 = 180
5x = 180 - 170
5x = 10
x = 10/5
x = 2
Jeremy caught 8 fish in a contest the mean weight of his fish was 4.1375. he forgot the weight of he 8th fish the first seven were 4.1 5.7 6.1 2.3 3.1 4.5 4.1 what is the wight of the 8th fish someone please help me i don't understand
Answer:
Step-by-step explanation:
Firstly,
What is the mean?
The mean is where you add up all the number then divide the total by how many numbers there are.
8th number?
1.4.1
2. 5.7
3. 6.1
4. 2.3
5. 3.1
6. 4.5
7. 4.1
8. x
Opposite way:
4.1 + 5.7 + 6.1 + 2.3 + 3.1 + 4.5 + 4.1 = 29.9
(29.9 x) / (8) = 3.7375
3.7375 + x = 4.1375
4.1375 - 3.7375 = 0.4

The scores for a state's peace officer training test are normally distributed with a mean of 55 and a standard deviation of 12. The test scores range from 0 to 100. A state agency will only interview applicants with test scores of 43 or greater. About what percent of the people have test scores that make them eligible to be interviewed?
Answer:
About 84% of the people have test scores that make them eligible to be interviewed
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 55, \sigma = 12[/tex]
A state agency will only interview applicants with test scores of 43 or greater. About what percent of the people have test scores that make them eligible to be interviewed?
This is 1 subtracted by the pvalue of Z when X = 43. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{43 - 55}{12}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587
1 - 0.1587 = 0.8413
Rounding to the nearest percent
About 84% of the people have test scores that make them eligible to be interviewed

Answer:
The cost per duck is $5.00 and $8.00 for chickens
Step-by-step explanation:
The equation would be like this:
50c + 30d = 550 (divide this by 10)
5c + 3d = 55
3d = 55 - 5c (multiply by 3)
9d = 165 - 15c
Next,
44c + 36d = 532 (divide this by 4)
11c + 9d = 133
11c + 165 - 15c = 133
11c - 15c = 133 - 165
-4c = -32 (divide by -4)
c = 8
Therefore, the cost of each chicken is $8.00
9d = 165 - 15c
9d = 165 - 15(8)
9d = 165 - 120
9d = 45 (divide by 9)
d = 5

Answer:
x r 1.26 cm
Step-by-step explanation:
This can easily be solved by congruence.
Both triangles have the same proportions.
9.8 : 8.8 = (2 + 9.2) : (x + 8.8)
Because these are proportional, we can use and write this as if they were fractions.
9.8 / 8.8 = (2 + 9.2) / (x + 8.8)
multiply crosswise, gives:
9.8 * (x + 8.8) = (2 + 9.2) * 8.8
9.8 * x + 9.8 * 8.8 = (11.2) * 8.8
9.8 * x + 86.24 = 98.56
9.8 * x = 98.56 - 86.24
9.8 * x = 12.32
Divide left and right of the = sign by 9.8 gives,
x = 12.32 / 9.8
x = 1.2(571428)
x = 1.26 cm

135 - 54 = 81
what is the surface area of a sphere whose great circle has a circumference of 16.4 inches
Answer:
[tex]85.6in^2[/tex]
Step-by-step explanation:
to find the surface area we need the radius of the sphere.
We can find the radius using the formula for circumference:
[tex]C=2\pi r[/tex]
we know that the circumference is
[tex]C=16.4in[/tex]
thus
[tex]16.4in=2\pi r[/tex]
solving for r:
[tex]r=\frac{16.4in}{2\pi} \\r=2.61in[/tex]
and now that we know the radius we calculate the surface area:
[tex]SA=4\pi r^2[/tex]
substituting r:
[tex]SA=4\pi(2.61014in)^2\\SA=4\pi(6.81in^2)\\SA=85.6in^2[/tex]
the surface area is equal to [tex]85.6in^2[/tex]
Question is in the image
Answer:
AB = 3.5 cm
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the length of prism )
Here V = 84 and h = 12 , thus
12A = 84 ( divide both sides by 12 )
A = 7 ← area of Δ ABC
Thus
[tex]\frac{1}{2}[/tex] × 4 × AB = 7
2AB = 7 ( divide both sides by 2 )
AB = 3.5 cm
Students who buy tickets at a local movie theater receive a 10% discount on the price of a ticket. What is the total price for 4 students' tickets if the regular cost per ticket is $6.00?
Answer: about $22 or 21.6 in decimal form
Step-by-step explanation: $6.00 - 10% is 5.4
5.4 + 5.4 +5.4+5.4 is 21.6 or $22 rounded up
write the equation of the line that passes through the points (-1, 2) and (6,3) in slope-intercept form
Answer:
y=(1/7)*x+(15/7)Step-by-step explanation:
first, lets find the slope:
m=(y2-y1)/(x2-x1)
m=(3-2)/(6-(-1))
m=1/7
y=(1/7)*x+b
to find b lets pug in a point we know into the equation:
3=(1/7)*6+b
21/7=6/7+b
b=(21/7)-(6/7)
b=15/7
now we know the equation in slope intercept form representing this function is:
y=(1/7)*x+(15/7)
Answer:
y= 1/7x+15/7
Step-by-step explanation:
points
(-1, 2) and (6, 3)
slope intercept form:
y= mx+b2= -m+b, 3= 6m+b ⇒ m= 1/7 ⇒ b= 2 1/7= 15/7
