Charlene and Gary want to make trail mix. In order to get the right balance of ingredients for their tastes they bought 3 pounds

AfilCa [17]

Answer:

$2.96

Step-by-step explanation:

3x$2.67=$8.01

3x$2.73=$8.19

5x$3.27=$16.35

$8.01+$8.19+$16.35=$32.55

This makes 11 pounds of trail mix.

$32.55 divided by 11 = $2.9590909 = $2.96

If events X and Y are independent, what must be true? Check all that apply.

larisa86 [58]

All these are true when X and Y are independent events:

1) The occurrence or lack of event X does not influence the occurrence of event Y, and the occurrence or lack of event Y does not influence the occurrence of event X.

2) P(X∩Y) = P(X) * P(Y)

3) P(X | Y) = P(X).... this is the probability of X given Y is equal to the probability of X.

4) P (Y | X) = P(Y)

5) P(A∪B) = P(A) + P(B) - P(A∩B)

An electrical engineer has on hand two boxes of resistors, with five resistors in each box. The resistors in the first box are l

Tju [1.3M]

Answer:

Step-by-step explanation:

given that an electrical engineer has on hand two boxes of resistors, with five resistors in each box. The resistors in the first box are labeled 10 ohms, but in fact their resistances are 9, 10, 11, 12, and 13 ohms. The resistors in the second box are labeled 20 ohms, but in fact their resistances are 18, 19, 20, 21, and 22 ohms. The EE chooses one resistor from each box and determines the resistance of each

Sample space for selecting one resistor from first box

= {9, 10, 11, 12, 13}

A = {11,12,13} (because >10)

Sample space for selecting one resistor from second box

={18,19,20,21,22}

B={18}

Sample space for sum would be

{27, 28, 29, 30, 31, 32, 33, 34, 35}

C = {(9,19) , (10,18)}

If ∆ABC and ∆GEF are congruent, the value of x is___? and the value of y is ___?

attashe74 [19]

Answer-

The value of y is 6 units.

Solution-

Given ∆ABC ≅ ∆GEF

If two triangles are congruent, then the corresponding sides are also congruent.

So,

EF = BC, GF = AC

Putting the values,

$\Rightarrow x-y=4$ --------------1

$\Rightarrow x-8=2$

$\Rightarrow x=10$ --------------------2

Putting the values of x in equation 1,

$\Rightarrow 10-y=4$

$\Rightarrow y=10-4=6$

Therefore, the value of y is 6 units.

16x^2-24x+7=0 equation and/or inequalities

Ivenika [448]

It is quadratic equation.
First we have find delta given by formula: delta= $b^{2}-4ac$
where our
a=16
b=-24
c=7
so, delta= $24^{2}-4*16*7=128$
Because delta is positive, there is real results.
Now we can use next formula x= $\frac{-b+ \sqrt{delta} }{2a}$
, to find roots (results, 2 results because its quadratic equation and delta is greater than 0)
x1= $\frac{24+ \sqrt{128} }{2*16} = \frac{3+ \sqrt{2} }{4}$
x2= $\frac{24- \sqrt{128} }{2*16} = \frac{3- \sqrt{2} }{4}$
