the grade 8 has hired a disk jockey the disk jockey takes 85$ plus 2 for each student that attends. The disk jockey was paid 197 how many students attended
Answer:
56 students
Step-by-step explanation:
The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

The compressive strength of samples of cement can be modeled by a normal distribution with a mean of 6000 kilograms per square centimeter and a standard deviation of 100 kilograms per square centimeter. (a) What is the probability that a samples strength is less than 6250 kilograms per square centimeter? (b) What is the probability that a samples strength is between 5800 and 5900 kilograms per square centimeter? (c) What strength is exceeded by 95% of the samples?
Answer
a
[tex]\Phi (2.5) = 0.9938[/tex]
b
[tex]P(5800 < X < 5900 ) = 0.13591 [/tex]
c
[tex]x = 5835.5 [/tex]
Question
From the question we are told that
The mean is [tex]\mu = 6000 \ kg/cm^2 [/tex]
The standard deviation is [tex]\sigma = 100 \ kg/ cm^2 [/tex]
Generally the probability that a samples strength is less than 6250 kilograms per square centimeter is mathematically represented as
[tex]P(X < 6250 ) = P(\frac{ X - \mu}{\sigma } < \frac{6250 - 6000 }{100} )[/tex]
Generally [tex]\frac{X - \mu }{\sigma } = Z(The \ standardized \ value \ of \ X )[/tex]
[tex]P(X < 6250 ) = P(Z< 2.5 )[/tex]
From the z-table
[tex]\Phi (2.5) = 0.9938[/tex]
Generally the probability that a samples strength is between 5800 and 5900 kilograms per square centimeter is mathematically represented as
[tex]P(5800 < X < 5900 ) = P(\frac{5800 - 6000}{100} < \frac{X -\mu}{\sigma} < \frac{5900 - 6000}{100} )[/tex]
=> [tex]P(5800 < X < 5900 ) = P(-2< Z< -1 )[/tex]
=> [tex]P(5800 < X < 5900 ) = P(Z < -1) - P( Z< -2 )[/tex]
From the z-table
[tex]P(Z < -2) = 0.02275[/tex]
and
[tex]P(Z < -1) = 0.15866[/tex]
So
[tex]P(5800 < X < 5900 ) = 0.15866 - 0.02275[/tex]
=> [tex]P(5800 < X < 5900 ) = 0.13591 [/tex]
Generally the strength that is exceeded by 95% is mathematically evaluated as
[tex]P(X > x) = 1- P(\frac{X - \mu }{\sigma} \le \frac{x- 6000}{100}) = 0.95 [/tex]
=> [tex]P(X > x) = P(Z \e \frac{x- 6000}{100}) = 0.05 [/tex]
From the normal distribution table the critical value of 0.05 is
[tex]z = - 1.645[/tex]
So
[tex]\frac{x- 6000}{100} = - 1.645[/tex]
=> [tex]x = (-1.645 * 100) + 6000[/tex]
=> [tex]x = 5835.5 [/tex]

What is the supplement of an angle that
measures 21 degrees?
Answer:
159°
Step-by-step explanation:
Supplements equal a total of 180°. The expression for these types of problems would be
180-x
In this case, x would be 21. Plug it in to our expression.

mckezie's rabbit ears 1/3 of a pound of food each day if mckenzie buys a 20 pound bag of food how many days will she be able to feed her rabbit
Answer:
She can feed her rabbit for 60 days!
Step-by-step explanation:
Turn 20 into a fraction:
[tex]\frac{20}{1}[/tex]
Make sure it has the same denominator:
(Remember: what you do to one side, you must do to the other)
[tex]\frac{20}{1} *\frac{3}{3}= \frac{60}{3}[/tex]
This means that if the rabbit eats 1/3 of a pound a day, she will be able to feed her rabbit for 60 days.

slope=4 and passes through (3,2)
Answer:
y = 4x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 , thus
y = 4x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = 12 + c ⇒ c = 2 - 12 = - 10
y = 4x - 10 ← equation of line

Which angle has a measure equal to the sum
of m_SQR and mzQRS?
O ZRSC
O LSRE
O ZDQS
O ZQSR
Answer:< RSC
Step-by-step explanation:
The angle has a measure equal to the sum of m <SQR and m <QRS is
m <RSC.
The correct option is A.
We have the information from which we can write
<SQR and < QRS are two interior angles of triangle QRS
Then, m<QSR = 180 - (sum of other 2 angles)
m<QSR = 180 - (m<SQR + m<QRS) (Angle sum property)
Also, m<RSC = 180 - m<QSR
Then <RSC = (m<SQR + m<QRS)
Thus, the ideal solution is A.
