Answer:

x=7

Step-by-step explanation:

4 (3x+4)= 100 ft (Perimeter = sum of all 4 sides)

12x + 16 =100 ft (Multiply length of one side by 4, which is number of side on a square)

12x = 84 (This is what is left after subtracting 16 form both sides of the equation making the equation still true)

x = 7 (84 divided by 7 to let X stand alone and get the value of x)

Answer:

It takes him 1 minute and 25 seconds

Step-by-step explanation:

5 ÷ 4 = 1.25

The number of laps per minute is 1.25 laps.

Given that, time = 4 minutes and the number of laps = 5.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

Number of laps per minute = Total number of laps/Number of minutes

= 5/4

= 1.25 laps

Therefore, the number of laps per minute is 1.25 laps.

Answer:

15

Step-by-step explanation:

I can't do it on paper, so I'll type it up for you so you can copy it down.

'Percent (%)' means 'out of one hundred':

75% = 75 'out of one hundred',

p% is read p 'percent',

75% = 75/100 = 75 ÷ 100.

'Percentage' is obtained by multiplying 20 by 75%.

75% × 20 =

(75 ÷ 100) × 20 =

Step-by-step explanation:

We have 8 men and 11 women

Number of ways of choosing a subcommittee of 4 men and 7 women

8C4 x 11C7

8!/(8-4)!4! x 11!/(11-7)!7!

= 8!/4!4! x 11!/4!7!

= (40320/24*24) x (39916800/24x5040)

= (40320/576) x (39916800/120960)

Answer:

200 sheep legs and 2 farmer legs, or 202 legs in total.

Step-by-step explanation:

One sheep has 4 legs. and there are 50 sheep. So, we have to multiply 50*4 to get 200. Then, we have to add the two legs the farmer has. 200 + 2 = 202. Therefore, there are 202 legs on the farm.

Answer:

Neither expression (A) nor expression (B) would be positive. A calculator is not required.

Step-by-step explanation:

Assume that [tex]A[/tex] and [tex]B[/tex] are both positive real numbers. Consider the property of logarithms with the same base:

[tex]\ln A + \ln B = \ln(A \cdot B)[/tex].

[tex]\displaystyle \ln A - \ln B = \ln\left(\frac{A}{B}\right)[/tex].

Apply these two properties to combine the logarithms in each expression into a one.

First expression:

[tex]\begin{aligned}&\ln 2+ \ln 3 + \ln 0.161 \\ &= \ln(2 \times 3) + \ln (0.161) \\ &= \ln(2 \times 3 \times 0.161) = \ln(0.966) \end{aligned}[/tex].

Second expression:

[tex]\begin{aligned}&\ln 3+ \ln (1.4) - \ln 16 \\ &= \ln(3 \times 1.4) - \ln (16) \\ &= \ln\left(\frac{3 \times 1.4}{16}\right) = \ln(0.2625) \end{aligned}[/tex].

The logarithm of a real number is positive if and only if that number is greater than one.

Neither [tex]0.966[/tex] nor [tex]0.2625[/tex] is greater than one. Therefore, neither of their respective logarithms would be positive.

Answer:

The value is  [tex]P(X > 3.30) = 0.12405[/tex]

Step-by-step explanation:

From the question we are told that

   The mean GPA is  [tex]\mu = 3.25[/tex]

   The standard deviation is [tex]\sigma = 0.75[/tex]

    The sample size is  n  =  300

Generally the standard error of mean is mathematically represented as

     [tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]\sigma_{\= x} = \frac{0.75}{\sqrt{300} }[/tex]

=>   [tex]\sigma_{\= x} = 0.0433[/tex]

Generally the  probability that a random sample of 300 students will have a mean GPA greater than 3.30 is mathematically represented as

     [tex]P(X > 3.30) = P(\frac{X - \mu}{\sigma_{\= x}} > \frac{3.30 -3.25}{ 0.0433} )[/tex]

[tex]\frac{\= X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ \= X )[/tex]

    [tex]P(X > 3.30) = P(Z> 1.155 )[/tex]

From the z table the probability of  (Z >  1.155 ) is

     [tex]P(Z> 1.155 ) = 0.12405[/tex]

   [tex]P(X > 3.30) = 0.12405[/tex]

Step-by-step explanation:

Answer:

x= -1/95

Step-by-step explanation:

Step 1: Subtract 110x from both sides.

15x+8−110x=110x+9−110x

−95x+8=9

Step 2: Subtract 8 from both sides.

−95x+8−8=9−8

−95x=1

Step 3: Divide both sides by -95.

−95x

−95

=

-1/95

x=

−1/95

Using distributive property the solution of the equation is x= −1/95

The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

This property is known by distributive law and applies to subtraction also.

Given that the equation; 15x + 8 = 110x + 9.

Step 1: Subtract 110x from both sides.

15x + 8 − 110x = 110x + 9 − 110x

−95x + 8 = 9

Step 2: Subtract 8 from both sides;

−95x + 8 − 8 = 9 − 8

−95x = 1

Step 3: Divide both sides by -95;

x= −1/95

Hence, Using distributive property the solution of the equation is x= −1/95

Answer:

The correct answer is:

c) The heights of children in a preschool

Step-by-step explanation:

Continuous variables are variables that can take on any value in a measuring series and scale. There is no limit to the possibilities of the data in a continuous variable. In this example, the heights of children can take on an infinite number of values, it may be 0.5m, 0.43m, 0.33m, etc.

Discrete variables, on the other hand, are variables that are obtained by counting. There is a limit to the possibilities that the values in this category can take on. For example, when counting the number of goals in a hockey game, it can be 2 goals, 10 goals 20 goals, but you cannot count 15.5 goals or 22.2 goals, the number is a whole discrete number. Hence options a, b and d are discrete variables.

Answer:

The correct answer is (second option):

The x-intercept is (6, 0); the y-intercept is (0, –9).

Step-by-step explanation:

Intercepts of a real function

Given a function y=f(x), the x-intercepts of f are those values of x that make y=0. The y-intercepts are those values of y that make x=0.

Our function is:

3x - 2y = 18

To find the x-intercept(s), we set y=0:

3x - 2(0) = 18

3x = 18

Solving:

x = 18 / 3 =6

The x-intercept is the point (6,0)

Now for the y-intercept(s), we set x=0:

3(0) - 2y = 18

-2y = 18

Solving:

y = 18 / (-2) = -9

The y-intercept is the point (0,-9)

The correct answer is (second option):

The x-intercept is (6, 0); the y-intercept is (0, –9).

The x-intercept is (6, 0); the y-intercept is (0, –9).

Answer:

24 ounces/ 2 packets = 12 ounces/ packet

Step-by-step explanation:

23 (12 ounces/packet) = 276 ounces of water

The the rate of ounces of water needed for each packet of flavoring would be 12.

Given is the packets of flavoring added to an specific amount of water to make soup.

Now, for 24 ounces of water, 2 packets of flavoring are needed.

Then, for 1 packet of flavoring, (24/2) or 12 ounces of water is needed.

For 5 packets of flavoring, (12 x 5) or 60 ounces of water is needed.

So, the rate of ounces of water needed for each packet of flavoring would be -

r = (60 - 24)/(5 - 2)

r = 36/3

r = 12

r = 12

Therefore, the the rate of ounces of water needed for each packet of flavoring would be 12.

Answer:

15/13

Step-by-step explanation:

Convert to improper fractions: 5/2 divided by 13/6

Multiply the first term by reciprocal: 5/2 * 6/13 = 30/26

Simplify: 30/26 can become 15/13

[tex] = 2 \frac{1}{2} \div 2 \frac{1}{6} [/tex]

[tex] = \frac{5}{2} \div \frac{13}{6} [/tex]

[tex] = \frac{5}{2} \times \frac{6}{13} [/tex]

[tex] = \frac{30}{26} [/tex]

[tex] = \frac{30 \div 2}{26 \div 2} [/tex]
