Step-by-step explanation:

Kilogram of flour needed to complete holiday order is atleast 175kg

Number of kilograms available = 34kg

Flour comes in bags each contain 23kg of flour

He wants to buy the smallest number of bags as possible and get the amount of flour he needs.

Let F = number of bags of flours Sergei needs to buy

F = (total number of kilograms needed - number of kilograms available) / kilograms per bag

F = (≥ 175 - 34) / 23

F = ≥ 141 / 23 = ≥ 6.1304347

Since flour is purchased per bag, the smallest number of bags he can possibly buy and still get the amount of flour he need = 7 bags

Answer:

y= -⅓x +⅓

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

This form is also known as the point-slope form.

Since the slope is given to be -⅓, m= -⅓.

y= -⅓x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -5, y=2,

2= -⅓(-5) +c

[tex]2 = \frac{5}{3} + c \\ c = 2 - \frac{5}{3} \\ c = \frac{1}{3} [/tex]

Thus, the equation of the line is y= -⅓x +⅓.

Answer:

Greatest = 10,049

Least = 9,950

Step-by-step explanation:

Given that:

attendance was rounded as 10,000 to the nearest hundred

The greatest number of people that could have attended the parade is 10,049, this is because, the digit in the hundred place is 0, hence, since the next digit after 0 is less than 5, all subsequent digits are rounded down to 0 = 10,000.

If the number is goes 1 above 10,049 to 10,050, the rounding to the nearest hundred gives 10,100

The least number of people that could have attended should be 9,950; the digit in the hundred place is 9, since the digit after 9 is up to 5, then it is rounded to 100 and added to 9,900 to give 10,000.

If the number goes 1 less than 9950 to 9949, then rounding to the nearest hundred gives 9900.

Answer:

x = 90

Step-by-step explanation:

We use the Definition of Corresponding Angles to help us solve for x:

∠1 = ∠4

Step 1: Write out equation

3x - 160 = x + 20

Step 2: Solve for x

2x - 160 = 20

2x = 180

x = 90

Answer:x=-4

Step-by-step explanation: combine like terms, add 4 and -7 which is -3 and add -4x and the -3x because they are like terms which is -7x so it should be -7x-3=25. then to get rid of the 3 add it to both sides so it would turn out like -7x=28 then divide the 7 on both sides= 28/ -7= -4

Step-by-step explanation:

It means for every 1 cm in the map 100 m will be represented correspondingly..

Hence.. 2 cm:200m and so on..

The two diagonal lines cross at (-3,5). We only need to worry about the x coordinate here, so x = -3 is what we're after. If x = -3, then f(x) and g(x) have the same y output meaning f(x) = g(x). That y output is y = 5.

Answer:

The correct option is b) [tex]P(D|A)=P(A|D)P(D)[/tex].

Step-by-step explanation:

The probability of selecting the different types of tires are:

P (A) = 0.40

P (B) = 0.15

P (C) = 0.45

The defective rate for the different types of tires are:

P (D|A) = 0.02

P (D|B) = 0.01

P (D|C) = 0.05

The formula to compute the probability that the tire is defective given that it is Brand A tire as follows:

[tex]P(D|A)=P(A|D)P(D)[/tex]

Answer:

y = 3 cos(π/5 x) + 5

Step-by-step explanation:

The amplitude is half the difference of the min and max.

A = (8 − 2) / 2

A = 3

The midline is the average of the min and max.

C = (8 + 2) / 2

C = 5

The difference in the x values of the min and max is half the period.

T/2 = 5 − 0

T = 10

The function is a maximum at x = 0, so use cosine.

y = 3 cos(2π/10 x) + 5

y = 3 cos(π/5 x) + 5

The formula of the function, where x is entered in radians is [tex]\rm y = 3 sin(\dfrac{\pi}{5}x) + 5[/tex] and this can be determined by using the given data.

Given :

The graph of a sinusoidal function has a maximum point at (0,8) and then has a minimum point at (5,2).

The following steps can be used in order to determine the formula of the function, where x is entered in radians:

Step 1 - The generalized sinusoidal function is given below:

[tex]\rm y = A sin(bx) + C[/tex]

where A is the amplitude.

Step 2 - Now, the value of A is given below:

[tex]\rm A = \dfrac{8-2}{2}[/tex]

A = 3

Step 3 - The value of C is calculated as:

[tex]\rm C = \dfrac{8+2}{2}[/tex]

C = 5

Step 4 - The time period is calculated as:

[tex]\rm \dfrac{T}{2}=5-0[/tex]

T = 10

Step 5 - So, the value of y is maximum at (x = 0).

[tex]\rm y = 3 sin(\dfrac{2\pi}{10}x) + 5[/tex]

[tex]\rm y = 3 sin(\dfrac{\pi}{5}x) + 5[/tex]

Answer:

Median

Step-by-step explanation:

The measure of central tendency is used to represent an entire group of data with a common single  number. There are three types of measure of central tendency, the mean , the median and the mode. Our focus here is on the median because in any skewed dataset, The median is the best form for a skewed type of distribution. The median is the middle number in an ordered set of data.

In a skewed type of distribution, the mode is the highest  point of the distribution. In the measure of central tendency, the mean is mostly influenced by the outliers and it is pulled towards  to the tail region of the distribution.

Answer:

$204.89

Step-by-step explanation:

Step 1

We have to first find the area of the circular sign.

Since the sign is circular in shape, we use the Area of Circle.

Area of a Circle = πr²

r = 1.5 feet

π = 3.14

Area of a Circle = 3.14 × 1.5²

= 7.065ft² or 7.065 square feet.

Step 2

We find out how much it cost to print the circular sign.

We are told in the question that

The printing company charges $29 per square foot

Hence,

1 square foot = $29

7.065 square feet =

Cross multiply

= 7.065 × $29

=$ 204.885

Approximately to the nearest cent, $204.89

Therefore, it will cost $204.89 to print the circular sign

Answer:

96

Step-by-step explanation:

First we need to know the mean of the Steve's scores on 6 of his tests. Given the six scores as 92, 78, 86, 92, 95, and 91.

Mean = sum of the scores/Total test taken

Mean = 92+78+86+92+95+ 91/6

Mean = 534/6

Mean = 89

If he took the seventh test and the mean score is raised by 1 them the new mean will be expressed as;

New mean = 92+78+86+92+95+ 91+x/7 = 89+1

Where x is the new score. Note that of a new score is added, the total year taken will also change to 7

To get x;

92+78+86+92+95+ 91+x/7 = 89+1

92+78+86+92+95+ 91+x/7 = 90

534+x/7 = 90

Cross multiply

533+x = 90×7

533+x = 630

x = 630-534

x = 96

Hence the score of the seventh test is 96

Answer:

The answer is

2/9=0.222222222.

Answer:

1. 49/150

2. 107/300

Step-by-step explanation:

Here is a probability question.

a. The first question asks us to find the probability of getting more than 4.

Now to do this, we look at our possible results when we roll the die, we can see that we can have 1-6.

But within this range, only two numbers are greater than 4, these are 5 and 6

Thus, to calculate the probability of getting either 5 or 6, we look at their frequencies, sum it up, then divide by the total number of times which the die was rolled.

The frequency of 5 is 47, while that of 6 is 51

The probability of getting more than 4 = Probability of getting 5 + Probability of getting 6 = (Frequency of 5 + Frequency of 6)/Total number of trials

= (47 + 51)/300 = 98/300 = 49/150

b. Probability of getting less than 3

Here, we proceed as we did in the first question. The numbers which are less than 3 are 1 and 2.

So the probability of getting less than 3 = Probability of getting 1 + Probability of getting 2 = (Frequency of 1 + Frequency of 2)/Total number of trials

Frequency of 1 = 62 while Frequency of 2 = 45

So, probability of getting less than 3 = (45 + 62)/300 = 107/300
