Answer:
D
Step-by-step explanation:
Here, we want to get the proportion that lies outside the given shown z-scores
Mathematically, that will be:
1 - proportion lying between the two z-scores
The probability lying between the two z-scores can be calculated using the normal distribution table
That will be;
P(-1.25 < x < 0.80)
From the table, this is;
0.68249
So the proportion lying outside will be;
1-0.68249 = 0.31751
This is approximately 0.3175

The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

Answer:
58 square units
Step-by-step explanation:
Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.
Area of the full larger rectangle:
Area = length × width
Length = |12 - 2| = 10 units
Width = |8 - 1| = 7 units
Area = 10 × 7 = 70 units²
Area of the unshaded small rectangle:
Length = |10 - 4| = 6 units
Width = |3 - 1| = 2 units
Area = 6 × 2 = 12 units²
Area of the shaded figure = 70 - 12 = 58 square units

Joe Casey, the star of the Placer County All-Star baseball team, has hit 11 home runs in the team's first thirty games. If he continues this pace how many home runs will he hit in a 162 game season? How many home runs is he expected to hit?
Answer: 59.4
Step-by-step explanation:
We can solve this by using direct proportion where y = kx
y = number of games
x = number of home runs
k = constant of proportionality
Since y = kx
30 = 11k
k = 30/11
The home runs will he hit in a 162 game season will then be:
= 162 ÷ 30/11
= 162 × 11/30
= 59.4
Answer: 59.4
Step-by-step explanation:
find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
f(x)=√(4-x), [-5,4]
================================================
Work Shown:
Compute the function value at the endpoints
[tex]f(x) = \sqrt{4-x}\\\\f(-5) = \sqrt{4-(-5)} = 3\\\\f(4) = \sqrt{4-4} = 0\\\\[/tex]
With a = -5 and b = 4, we have
[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(4)-f(-5)}{4-(-5)}\\\\f'(c) = \frac{0-3}{9}\\\\f'(c) = -\frac{1}{3}\\\\[/tex]
So,
[tex]f(x) = \sqrt{4-x}\\\\f'(x) = -\frac{1}{2\sqrt{4-x}}\\\\f'(c) = -\frac{1}{3}\\\\-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\[/tex]
Use algebra to solve for c
[tex]-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\\frac{1}{2\sqrt{4-c}} = \frac{1}{3}\\\\3 = 2\sqrt{4-c}\\\\2\sqrt{4-c} = 3\\\\\sqrt{4-c} = \frac{3}{2}\\\\4-c = \frac{9}{4}\\\\c = 4-\frac{9}{4}\\\\c = \frac{16-9}{4}\\\\c = \frac{7}{4}\\\\[/tex]
Can y’all help me and tell me what the answer is please I’m a bit stuck
Answer:
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
Step-by-step explanation:
We need to find mistake make in work below:
[tex](-2x^4)^4=-16x^{16}[/tex]
The mistake here is when we have even power, the negative sign gets positive i.e [tex](-a)^m=a^m[/tex] if m is even
so, in our case it would be:
[tex](-2x^4)^4=16x^{16}[/tex]
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..
Answer:
[tex]y > 3\cdot x + 5[/tex]
Step-by-step explanation:
Let [tex]A(x,y) = (-2,4)[/tex] and [tex]y = 3\cdot x + 5[/tex]. Now we evaluate the given function at [tex]x = -2[/tex]:
[tex]y = 3\cdot x + 5[/tex] (1)
[tex]y = 3\cdot (-2)+5[/tex]
[tex]y = -6 +5[/tex]
[tex]y = -1[/tex]
Which means that [tex]y[/tex] is less than the y-component of A. Therefore, the right answer is [tex]y > 3\cdot x + 5[/tex].

Steve Conway wants his team to win more than 57 games this year. His team has already won 2 games this season and there are 5 more months to play. Based on his goal, how many games must his team win per month? Write answer as an inequality.
Answer:
11
Explanation:
Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.
The number of games must his team win per month will be;
⇒ x > 11
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Steve Conway wants his team to win more than 57 games this year.
And, His team has already won 2 games this season and there are 5 more months to play.
Now,
Let number of games must his team win per month = x
So, We can formulate the inequality as;
⇒ 5x + 2 > 57
Solve for x as;
⇒ 5x > 57 - 2
⇒ 5x > 55
⇒ x > 11
Thus, The number of games must his team win per month will be;
⇒ x > 11

An angle's measure is 43 less than 6 times the measure of its
complement. Find the measure of both angles,
Step-by-step explanation:
A = 6(90-A)-43 Simplify and solve for A.
A = 540-6A-43
A = 497-6A Add 6A to both sides.
7A = 497 Divide both sides by 7.
A = 71 degrees
The complement of A = 90-A = 09-71 = 19

Given f(x) = 5x + 1 divided by 2, solve for f^-1(8).
O a
3
O b
7
О c
10
O d
20
Answer:
3Step-by-step explanation:
Given the function f(x) = (5x+1)/2
We are to find the inverse first as shown;
let y = f(x)
y = (5x+1)/2
Replace y with x
x = (5y+1)/2
Make y the subject of the formula;
2x = 5y+1
5y = 2x-1
y = (2x-1)/5
f^-1(x) = (2x-1)/5
f^-1(8) = 2(8)-1/5
f^-1(8) = 16-1/5
f^-1(8) = 15/5
f^-1(8) = 3
Hence the answer is 3
The record for the most rolls of wrapping paper sold for the school fundraiser is 593. Let w be the number of rolls of wrapping paper sold. Tell if the equation or inequality represents a number that would beat the school record.
Answer:
w ≤ 593
Step-by-step explanation:
Missing option;
w ≥ 593
w > 593
w ≤ 593
593 < w
Explanation:
w ≥ 593 No
Number of wrapping paper sold never be more than 593.
w > 593 no
Number of wrapping paper sold never be more than 593.
w ≤ 593 yes
Number of wrapping paper sold will be equal or less than 593.

8x-9+53=180 solve for x
Answer:
x=17
Step-by-step explanation:
1: Simplify both sides of the equation.
8x−9+53=180
8x+−9+53=180
(8x)+(−9+53)=180(Combine Like Terms)
8x+44=180
8x+44=180
2: Subtract 44 from both sides.
8x+44−44=180−44
8x=136
3: Divide both sides by 8.
(8x=136 )/8
x=17
