Answer:

30 portions of salad

Step-by-step explanation:

Given that :

2/5 pounds of canned tuna = 5 portions of salad

For every 2 onions used, 1 1/5 pounds of canned tuna is used ;

Number of onions used = 4

If 4 onions were used, number of canned tuna used is ;

4 /2 * 1 1/5

= 2 * 1 1/5

= 2 * 6/5

= 12 / 5 = 2 2/5 pounds of canned tuna

Number of Portions of salad made :

2/5 pounds = 5 portions of salad

12/5 pounds = x

2/5 * x = 12/5 * 5

2/5x = 60 /5

2/5 x = 12

x = 12 ÷ 2/5

x = 12 * 5 /2

x = 60/2

x = 30 portions of salad

Answer:

A sequence

Step-by-step explanation:

A sequence is a collection of things arranged such that there is order or form in the collection. The components of a sequence are called elements or terms

The pattern in a sequence is achieved by the implementation of well defined rules, such that a term more than one space from a known term can be calculated

An example of a sequence is the following numbers;

1, 6, 11, 17, 22, 28,...

It can be observed that each subsequent term of the sequence is larger than the previous term by 5, therefore, 5 is known as the common difference, and the sequence is known as an arithmetic progression.

Answer:His error lies in  the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

Step-by-step explanation:

Step 1

Rewriting this to a mathematical expression 2 cubed (3 minus 1) + 4 (8 minus 12) and solving correctly gives

2³(3-1)+ 4(8-12)

=8(2) + 4(-4)

= 16 +(-16)

16-16=0

Step 2-----Jacki's evaluation

2³(3-1)+ 4(8-12)

 = 2³(2) +4(4)

= 8(2) +16= 16+ 16 =32

His error lies in  the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

Answer:

y intercept is 1/3

Step-by-step explanation:

Answer:

Point-slope form

y-b = m(x-a)

y- 725 = 12(x -50)

y -725 = 12x -600

  +725         +725

Slope Intercep form

y = mx + b

y = 12x + 125

Step-by-step explanation:

The slope- intercept form is y = 12x + 125 and the y- intercept is 125.

The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable.

Given:

y − 725 = 12( x −50 )

Now, arranging in the form of slope- intercept form

y- 725 = 12 x - 600

y = 12x - 600 + 725

y = 12x + 125

as, the slope intercept form is

y= mx + b

Hence, the y- intercept is  125

Answer:

Subtract 5 from both sides of the equation.

Step-by-step explanation:

Given the function:

[tex]5+|2x-4|=9[/tex]

First step to solve the above equation is to isolate the absolute value function i.e. one side(either Left Hand Side or Right Hand Side) of equation must contain the terms containing the absolute function only.

In Left Hand Side, we have the absolute value function added to 5.

If we subtract 5 from both the sides, we get:

[tex]5+|2x-4|-5=9-5\\\Rightarrow |2x-4|=4[/tex]

So, after "subtracting 5 from both sides of the equation", the absolute function gets isolated on the left hand side of the equation i.e. Left Hand Side contains the absolute value function only.

Explanation I got it right on the test :)

Options :

A.) On average, the height of a child is 80% of the age of the child.

B.) The least-squares regression line of height versus age will have a slope of 0.8.

C.) The proportion of the variation in height that is explained by a regression on age is 0.64.

D.) The least-squares regression line will correctly predict height based on age 80% of the time.

E.) The least-squares regression line will correctly predict height based on age 64% of the time.

Answer:

C.) The proportion of the variation in height that is explained by a regression on age is 0.64.

Step-by-step explanation: from the scenario stated above, The correlation Coefficient R = 0.8, which shows the strength of relationship between age and height of children. From the value of correlation Coefficient Given, we can obtain the Coefficient of determination (R²) which gives the percentage of Variation which can be explained by the regression model.

Hence the Coefficient of determination (R²) = 0.8² = 0.64. Hence, the proportion of variation in height of children which can he due to age is 0.64 while 0.36 can be based on other factors.

Based on the line created from the data to the height of a child based on age the correct statement is given by: Option C.) The proportion of the variation in height that is explained by a regression on age is 0.64.

For that, we can use the coefficient of determination.

The coefficient of determination is square of correlation coefficient and thus, ranges from 0 to 1.

The coefficient of determination tells for unit variation in one variable will lead to how much variation in other variable and vice versa.

Let we take:

X = age of children of the sample considered

Y = height of children of the sample considered

Then, as it is given that:

[tex]r(X, Y) = 0.8[/tex]

Thus, the coefficient of determination is: [tex]r^2 = 0.8^2 = 0.64[/tex]

Thus, we get that 0.64 of the variation in the height is explained by the age of the children.

Thus, the true statement is:

Option C.) The proportion of the variation in height that is explained by a regression on age is 0.64.

Step-by-step explanation

19th term of an AP = 52

38th term = 128

the sum of the first 56 terms

We know that,

nth term of an AP – a(n) = a + (n - 1)d

Hence,

→ a + (19 - 1)d = 52

→ a + 18d = 52 -- equation (1)

Similarly,

→ a + (38 - 1)d = 128

→ a + 37d = 128 -- equation (2)

Subtract equation (1) from (2).

→ a + 37d - (a + 18d) = 128 - 52

→ a + 37d - a - 18d = 76

→ 19d = 76

→ d = 76/19

→ d = 4

Substitute the value of d in equation (1).

→ a + 18 * 4 = 52

→ a = 52 - 72

→ a = - 20

We know,

Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]

Hence,

→ S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]

→ S(56) = 28 * [ - 40 + 55 * 4 ]

→ S(56) = 28 * [ - 40 + 220 ]

→ S(56) = 28 * (180)

→ S(56) = 5040

Hence, the sum of first 56 terms of the given AP is 5040.

I hope it will help you.

Regards.

The sum of the first 56 terms of the given AP is 5040.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression. A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.

Given that in an AP. 19th term is 52 and 38th term is 128.

nth term of an AP – a(n) = a + (n - 1)d

a + (19 - 1)d = 52

a + 18d = 52 -- equation (1)

Similarly,

a + (38 - 1)d = 128

a + 37d = 128 -- equation (2)

Subtract equation (1) from (2).

a + 37d - (a + 18d) = 128 - 52

a + 37d - a - 18d = 76

19d = 76

d = 76/19

d = 4

Substitute the value of d in equation (1).

a + 18 * 4 = 52

a = 52 - 72

a = - 20

Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]

S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]

S(56) = 28 * [ - 40 + 55 * 4 ]

S(56) = 28 * [ - 40 + 220 ]

S(56) = 28 * (180)

\S(56) = 5040

Hence, the sum of the first 56 terms of the given AP is 5040.

Step-by-step explanation:

Triangle inequality theorem : Any side of a triangle must be shorter than the other two sides added together.

Let's check if this theorem holds good with these side lengths

3< 9+5 (holds good)

5< 9+3 (holds good)

9< 5+3 (does not hold good)

So, these 3 sides cannot make a triangle

We know,

1 hour = 60 minutes

Then 4 hours = 4×60= 240 minutes
