Can someone help me with this geometry question!? ASAP

The z score of a student who scores a 92 on the final exam is 2.67.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where x is the raw score, μ is the mean and σ is the standard deviation

Given that σ = 6, μ = 76. For a raw score of 92:

z = (92 - 76) / 6 = 2.67

The z score of a student who scores a 92 on the final exam is 2.67.

The computer will cost $924.96 after 6% tax.

The initial payment of the laptop made = $150.00

The remaining balance that would be made = 12 × 69.50

=$834

Therefore total cost of laptop before tax = 834 + 150

= $984

But tax is 6% of total cost =

[tex] \frac{6}{100} \times 984[/tex]

[tex] \frac{5904}{100} [/tex]

= $59.04

Therefore, total cost of laptop after tax = 984 - 59.04

= $924.96

Probabilities are used to determine the chances of events

The probability that a teacher is a woman or teaches math is 45.24%

The given parameters are:

Teachers = 84

Math teachers = 12

Female teachers = 32

Female math teachers = 6

The number of female or math teachers is:

Female or math = Math + Female - Female math

So, we have:

Female or math = 12 + 32 - 6

Female or math = 38

The probability that a teacher is a woman or teaches math is:

[tex]Pr = \frac{38}{84}[/tex]

Simplify

[tex]Pr = \frac{19}{42}[/tex]

Express as percentage

[tex]Pr = 45.24\%[/tex]

Hence, the probability that a teacher is a woman or teaches math is 45.24%

392.66

Step-by-step explanation:

Answer:

392.66

Step-by-step explanation:

Our equation at first is (6.82x105) - (3.11x104)

We first multiply 6.82 and 105 and we get 716.1

Now our equation is 716.1 - (3.11x104)

Now we multiply 3.11 and 104 and we get 323.44

We now subtract 716.1-323.44 and we get our final answer of…

Answer:

  14. ∠UVS = 63.6°

  15. ∠TWU = 90°

  16. ∠TUV = 116.4°

  17. UW = √111 ≈ 10.5

  18. SU = 2√111 ≈ 21.1

  19. VT = 34

Step-by-step explanation:

The relevant relations for a rhombus are ...

__

Angle UVS is double the measure of angle UVW. 2×31.8° = 63.6°.

  angle UVS = 63.6°

__

As we said above, the angles where the diagonals cross are right angles.

  angle TWU = 90°

__

Angle TUV is supplementary to angle UVS. 180° -63.6° = 116.4°

  angle TUV = 116.4°

__

UW is found using the Pythagorean theorem.

  UW² +TW² = TU²

  UW² = TU² -TW² = 20² -17² = 111

  UW = √111 ≈ 10.536

__

The whole diagonal is twice the measure of half of it. SU = 2×UW

  SU = 2√111 ≈ 20.071

__

The whole diagonal is twice the measure of half of it. 2×17 = 34

  VT = 34

Answer:

m=−2/3 or m=−4/3

Step-by-step explanation:

Step 1: Subtract -3m^2+9 from both sides.

6m^2+18m+17−(−3m^2+9)=−3m^2+9−(−3m^2+9)

9m^2+18m+8=0

Step 2: Factor left side of the equation.

(3m+2)(3m+4)=0

Step 3: Set factors equal to 0.

3m+2=0 or 3m+4=0

m=−2/3 or m=−4/3

Answer:

ok so we trying to find out how many each batted so lets make this a system of equation

first we now that combined they are 232 so

a+b=232

then we now that b is 18 less then a so

a-18=b

the system of equation is

a+b=232

a-18=b

so we now what b is so we can just plug that in

a+a-18=232

2a-18=232

2a=250

a=125

then we can just plug this back in

125+b=232

b=107

a=125

b=107
