Jackie bougth red and green binders and paid $2.25 for each red binder and $3.24 for each green binder and spent a total of $21.

Alenkasestr [34]

Answer:

4 each of red and green binders.

Step-by-step explanation:

Given: Price of each red binder is $2.25.

Price of each green binder is $3.24.

Total Jackie paid is $21.96.

Lets assume the number of red binder bought be "x".

∴ Total amount paid for red binder= $number\ of\ red\ binder \times price\ for\ each\ red\ binder$

⇒ Total amount paid for red binder= $x\times \$ 2.25= \$ 2.25x$

Now, finding the amount paid for green binder.

As we know the total amount paid by Jackie is $21.96 and she bought same number for each binder.

Jackie paid for x number of green binder= $\$ 3.24\times x= \$ 3.24x$

Next, we can write an equation on total amount paid for Green binder to find value of x.

∴ $\$ 21.96-\$ 2.25x= \$ 3.24x$

Solving the equation.

$\$ 21.96-\$ 2.25x= \$ 3.24x$

Adding both side by \$ 2.25x

⇒ $\$ 21.96= \$ 3.24x+\$ 2.25x$

⇒ $\$ 5.49x = \$ 21.96$

cross multiplying both side.

⇒ $x= \frac{21.96}{5.49} = 4$

∴ x= 4

Hence, Jackie bought 4 each of red and green binders as she bought same number of each binders.

The zeroes of the function are . of the zeroes have a multiplicity of 2.

NISA [10]

Answer:

The three roots have a multiplicity of 2

Step-by-step explanation:

The zeros of the function refers to those points on the x-axis on which the curve passes through

These are the points -2,0 and 4

Now we want to determine which of these points has a multiplicity of 2?

The correct answer is that all have a multiplicity of 2 since 2 can be factored out

2(-1) , 2(0) and 2(2)

Delta Airlines quotes a flight time of 2 hours for its flights from Cincinnati to Tampa, meaning that an on-time flight would ar

ddd [48]

Answer:

a) Attached

b) P=0.60

c) P=0.80

d) The expected flight time is E(t)=122.5

Step-by-step explanation:

The distribution is uniform between 1 hour and 50 minutes (110 min) and 135 min.

The height of the probability function will be:

$h=\frac{1}{Max-Min}=\frac{1}{135-110} =\frac{1}{25}$

Then the probability distribution can be defined as:

$f(t)=\frac{1}{25}=0.04 \,\,\,\,\\\\t\in[110,135]$

b) No more than 5 minutes late means the flight time is 125 or less.

The probability of having a flight time of 125 or less is P=0.60:

$F(T$

c) More than 10 minutes late means 130 minutes or more

The probability of having a flight time of 130 or more is P=0.80:

$F(T>t)=1-0.04(t-110)\\\\F(T>130)=1-0.04*(130-110)=1-0.04*20=1-0.8=0.2$

d) The expected flight time is E(t)=122.5

$E(t)=\frac{1}{2}(max+min)= \frac{1}{2}(135+110)=\frac{1}{2}*245=122.5$

If m<mkl=83. m<jkl=127. and m<jkm=(9x-10). find the value of x

kirza4 [7]

MKL = 83, JKL = 127, JKM = 9x - 10 given

JKL + MKL = JKM angle addition postulate

127 + 83 = 9x - 10 substitution

210 = 9x - 10 simplify (add like terms)

220 = 9x addition property of equality

$\frac{220}{9}$ = x
