Answer:

j=15

Step-by-step explanation:

Let's set up an equation:

2j+7=37

Subtract both sides by 7

2j=30

Divide both sides by 2

j=15

Answer:

15

Step-by-step explanation:

37=2j+7

so subract 7 from both sides

30=2j

then divide by 2 on each side

j=15

Using the normal distribution, it is found that there is a 0.0139 = 1.39% probability that his systolic blood pressure will be greater than 160 mm.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The probability that his systolic blood pressure will be greater than 160 mm is 1 subtracted by the p-value of Z when X = 160, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{160 - 138}{10}[/tex]

[tex]Z = 2.2[/tex]

[tex]Z = 2.2[/tex] has a p-value of 0.9861.

1 - 0.9861 = 0.0139

0.0139 = 1.39% probability that his systolic blood pressure will be greater than 160 mm.

Answer:

(7, 3)

Step-by-step explanation:

Step 1 : multiply so you can eliminate y and solve for x.

2(5x - 3y = 26)

3(4x + 2y = 34)

  10x - 6y = 52

+ 12x + 6y = 102

----------------------

22x = 154

x = 7

Now, plug in the value of x into one of the equations to solve for y.

5x - 3y = 26

5(7) - 3y = 26

35 - 26 = 3y

y = 9/3

y = 3

Answer:

We need to read the graph to see which are the two quantities related and how these are related.

The two quantities on the graph are:

Such that the distance from Elena's house is a function of the time.

We need to only read graph A, notice that she is coming back from school and going home, the graph starts at a high value and ends at zero. So we can assume that the vertical zero represents her home.

We know two events, first, she goes home and needs to come back to search for something, this is represented with the first "inverted peak" of graph A, then we have a constant line, that represents the time she is in the school looking something in her locker.

Then she goes home again, this time she finds a friend and goes to the library (this is why the line goes up again) and then she stops at the library for some time (this is why the line is horizontal for some time). Finally, she goes home, represented by the last segment of the line that intercepts the horizontal axis.

Then the two things represented in the graph are:

Distance from Elena's house (in the vertical axis) and time (in the horizontal axis).

This means that the distance from Elena's house is a function of time.

(The quantity in the vertical axis is a function of the quantity in the horizontal axis).

Answer:

Step-by-step explanation:

More than you might think.

She takes 1 key in her hand. It might take her 11 tries to find the right locker

Now she knows there are 10 other lockers that will be opened by the key in her hand.

So far that's 11 * 10 = 110

Now she has 9 lockers for the 3rd key.  She might need to check all 9 of them before she finds the right one

9 * 110 = 990 tries for the first 3 keys.

11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 39 916 800

The length of the diagonal is 11.879 units

Step-by-step explanation:

On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

where a and b are the sides, and c is the diagonal.

[tex]\rightarrow8.4^2+8.4^2=c^2\\\rightarrow70.56+70.56=c^2\\\rightarrow c^2=141.12\\\rightarrow c\approx11.879[/tex]

Answer:

The value of x is {log (1±√5)/2 }/{log (3/2)}.

Step-by-step explanation:

Given equation is 4^x + 6^x = 9^x

On dividing by 4^x both sides , then

⇛(4^x+6^x)/(4^x) = (9^x)/(4^x)

⇛(4^x/4^x) +(6^x/4^x) = 9^x/4^x

⇛1+(6^x/4^x) = 9^x/4^x

It can be arranged as

⇛9^x/4^x = (6^x/4^x)+1

On applying exponent radical rule of both sides then

Since, (a/b)^m= a^m /b^m

Where, a = 9, b = 4 and m = x.

Similarly, apply this rule also on RHS.

Where, a = 6, b = 4 and m = x then

⇛(9/4)^x = (6/4)^x +1

⇛(3²/2²)^x = {(3/2)^x} + 1

⇛{(3/2)²}^x = {(3/2)^x} + 1

Again applying exponent rule on LHS.

Since, (a^m)^n = a^mn

Where, a = (3/2), m = 2 and n = x.

⇛(3/2)^(2x) = (3/2)^x +1

⇛{(3/2)^x}^2 = (3/2)^x +1

Put (3/2)^x = a then

⇛a² = a+1

Shift variable (a) RHS from LHS, changing it's sign.

⇛a²-a = 1

⇛a²-(2/2) a = 1

⇛a²-2(a)(1/2) = 1

On adding (1/2)² both sides then

⇛a²-2(a)(1/2)+(1/2)² = 1+(1/2)²

⇛{a-(1/2)}² = 1+(1/4)

⇛{a-(1/2)}² = (1/1) + (1/4)

Take the LCM of 1 and 4 is 4 on RHS.

⇛{a-(1/2)}² = {(1*4 + 1*1)/4}

⇛{a-(1/2)}² = {(4+1)/4}

⇛{a-(1/2)}² = (5/4)

⇛a-(1/2) =±√(5/4)

⇛a-(1/2) =±√5/2

Shift the fraction number -(1/2) from LHS to RHS, changing it's sign.

⇛a =(1/2)±√5/2

Take the LCM of 2 and 2 is 2 as common.

⇛a = (1±√5)/2

⇛a = (1+√5)/2 or (1-√5)/2

⇛(3/2)^x = (1+√5)/2 or (3/2)^x = (1-√5)/2

On taking logarithms both sides then

⇛log (3/2)^x = log (1+√5)/2

⇛x log (3/2) = log (1+√5)/2

On applying log a^m = m log a, we get

⇛x ={log (1+√5)/2 }/{log (3/2)} and

Therefore, x = {log (1-√5)/2 }/{log (3/2)}

Answer: Hence, the value of x for the given equation is {log (1±√5)/2 }/{log (3/2)}.
