Answer:

That is false.

The sum of any two sides in a triangle must be greater than the length of the third side.

We can see that: 7+9 = 16, and 16 is not greater than 18.

So, this is not a triangle.

Step-by-step explanation:

Both equations have -7y. You can eliminate them by subtracting one equation from the other:

Multiply equation 1 by -1, then add it to equation 2:

-2x + 7y = 74

3x - 7y = -83

———————

x = -9

2x - 7y = -74

2(-9) - 7y = -74

-7y = -56

Y = 8

(x,y) = (-9, 8)

Answer:

The procedure does results in a binomial distribution.

Step-by-step explanation:

For a binomial probability distribution to be applicable, certain conditions have to be met which are :

There must be a fixed number of observations ; here the number of observations are : 79

All observations must be independent ; the observations are independent ; odd or even

Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even

The probability of success must be equally likely for each observation.

Hence, the procedure results in a binomial probability distribution.

Answer:

A number line with a closed circle on 6 and shading to the right

Step-by-step explanation:

The best estimate for the cost of the sewing project is between $30 and $40. Hence option 'a' is correct.

Use the concept of fraction defined as:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.

It can be written as the form of [tex]p : q[/tex], which is equivalent to p / q.

Given that,

The sewing project also requires 3 1/4 yards of material selling for $3 per yard.

To calculate the cost of the sewing project:

Compute the cost of each type of material separately and then add them together.

For the first type of material:

We need [tex]6\dfrac{1}{8}[/tex] yards, which is equivalent to 6.125 yards.

The cost of this material would be,

6.125 x 4 = $24.50

For the second type of material:

We need [tex]3\dfrac{1}{4}[/tex] yards, which is equivalent to 3.25 yards.

The cost of this material would be,

3.25 x 3 = $9.75.

Now, add the costs of the two types of materials together:

$24.50 + $9.75 = $34.25.

Hence,

The cost of the project would be between $30 and $40,

Which is option a.

Answer:

-4.01, -4, -7

Step-by-step explanation:

equation:

-x + 6 ≥ 10

substitute each number for x

- (-3.9) + 6 ≥ 10 = (negatives cancel each other out) 3.9 + 6 = 9.9 ≥ 10 (incorrect)

-4 + 6 ≥ 10 = 2 ≥ 10 (incorrect)

The value of product of x and y is, 21

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

WE have to given that;

System of equation ae,

x + 4y = 19  .. (i)

x - 2y = 1 .. (ii)

From (i);

x + 4y = 19

x = 19 - 4y

substitute it for the (ii) equation;

x - 2y = 1

19 - 4y - 2y = 1

19 - 6y = 1

-6y = -18

y = 3

Hence, From (i);

x + 4y = 19

x + 12 = 19

x = 7

So, The value of product of x and y is,

x × y = 3 × 7 = 21

Answer:

h(0)=10

h(4)=16

Step-by-step explanation:

for h(0) you would need to do the second equation because it is within the bounds of the variable.

h(0)= 2x^2 - 3x + 10

anything times 0 is 0

so 2(0)^2 - 3(0) + 10=

0-0+10=

h(4) would use the third equation since it's the only one that agrees with the variable 4

Answer:

0.76 = 76% probability that a tourist visited at least one of these places

Step-by-step explanation:

I am going to solve this question using the probabilities as Venn sets.

We have that:

Event A: Tourist visited Beinjing.

Event B: Tourist visited Xi'an.

61 percent of the tourists to China visited the Forbidden City, the Temple of Heaven, the Great Wall, and other historical sites in or near Beijing.

This means that [tex]P(A) = 0.61[/tex]

33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years.

This means that [tex]P(B) = 0.33[/tex]

18 percent of the tourists went to both Beijing and Xi'an.

This means that [tex]P(A \cap B) = 0.18[/tex]

What is the probability that a tourist visited at least one of these places?

This is

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

We already found these values. So

[tex]P(A \cup B) = 0.61 + 0.33 - 0.18 = 0.76[/tex]

0.76 = 76% probability that a tourist visited at least one of these places

Answer:

Pretzels: 30 ounces, Nuts: 15 ounces

Step-by-step explanation:

Trust me.

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jamal is making a snack mix with pretzels and nuts.

And, For every ounce of nuts, he will use 2 ounces of pretzels.

Total number of snake mix = 45 ounces

Now,

Let number of ounces of pretzels = y

Let number of ounces of nuts = x

So, We can formulate;

⇒ x = 2y    ... (i)

And, x + y = 45     .... (ii)

Substitute the value of x in equation (ii) , we get;

x + y = 45  

2y + y = 45  

3y = 45

y = 15

And,

x + y = 45  

x + 15 = 45

x = 30

Therefore,

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

−35.713332 ; 0.313332

Step-by-step explanation:

Given that:

Sample size, n1 = 11

Sample mean, x1 = 79

Standard deviation, s1 = 18.25

Sample size, n2 = 18

Sample mean, x2 = 96.70

Standard deviation, s2 = 20.25

df = n1 + n2 - 2 ; 11 + 18 - 2 = 27

Tcritical = T0.01, 27 = 2.473

S = sqrt[(s1²/n1) + (s2²/n2)]

S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]

S = 7.284

(μ1 - μ2) = (x1 - x2) ± Tcritical * S

(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284

(μ1 - μ2) = - 17.7 ± 18.013332

-17.7 - 18.013332 ; - 17.7 + 18.013332
