Answer:

625 is the sum of first 49 odd numbers.

Step-by-step explanation:

Add the all odd numbers between 1 - 49.

1+3+5+7+9+11+ 13+ 15+17+ 19+21+23+25+ 27+29+31+33+35+37+39+41+43+45+ 47+ 49 = 625

Answer:

18 minutes

Step-by-step explanation:

900/250 is 3.6

3.6 * 5 = 18

Answer:

18 minutes

Step-by-step explanation:

Hi! Okay, let's get started!

Let's find her rate per minute first = 250/50 = 50 words per minute

Now, we need to find the time for 900 words, so we do 900/50, which gives you 18, or 18 minutes!

Hope that helps! :)

Answer:

I = p× r× t

300×8×4

pinicipal × rate × time

That is the formula

the answer is 300×8×4= 9600

Answer:

(-8)x(-8)=64

Step-by-step explanation:

(-8)²

(-8)x(-8)=64

The repeated multiplication of (-8)² is -8 x (-8).

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as 34, where 4 is the exponent and 3 is the base.

We know that exponents and power used to express powers.

like if we have 5³ then 5 is multiplied to itself 3 times.

Here we have (-8)² then we can write

(-8)²

= -8 x -8

= 8 x 8

= 64.

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

whole numbers are higher than 10, nutural numbers are like 1 2 3 4 5 while integers are like fractions

Answer:

A dot plot is similar to histogram wherein they show the frequency of data. In this kind of plot, instead of bars, dots are stacked on their corresponding bin. The bins here are the number of pets, while the dots are the students. So, the 2 dots above number 3 signifies that, there are two students with three pets. The answer is A.

Step-by-step explanation:

Answer:

a. 0.56

b. 0.262

c. 672

Step-by-step explanation:

Confidence interval:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The margin of error is the result of the subtraction between these two bounds divided by 2.

a. The point estimate of the population proportion is

Mean of the bounds. So

(0.298 + 0.822)/2 = 0.56

b. The margin of error is

(0.822-0.298)/2 = 0.262

c. The number of individuals in the sample with the specified characteristic is

0.56 of 1200. So

0.56*1200 = 672

Answer:

Step-by-step explanation:

Area of a triangle = [tex]A=\frac{bh}{2}[/tex]

Where b = base and h = height

The shown triangle has a base length of 3 cm and a height of 8 cm

Using these dimensions we plug in the values into the formula

[tex]A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\A=12[/tex]

Hence, the area of the triangle is 12 square centimeters

Answer:

12 centimeters^2

Step-by-step explanation:

We find the area of a triangle by multiplying the base and width of the triangle before dividing by 2

Why because if u put 2 triangles together you get a rectangle

3*8=24

24/2=12

Since p-value > ∝, H0 is accepted

Total  20          21927.69 1096.385                                          

1. H0 hypothesis

Since p-value > ∝, H0 is accepted.

Hence the averages of all groups considered to be equal.

Or the difference between the averages of all groups is not big enough to reject H0.

2. P-value

P-value equals 0.999. This means that if we would reject H0, the chance of type1 error (rejecting a correct H0) would be too high i.e  (99.99%)

The bigger  p-value  supports H0.

3. The statistics

The test statistic F equals 0.020, which lies in the accepted range: [-∞ : 2.8477]

In how many ways can be selection be done

Since orders does matter, then it is permutation.

This is calculated as:

[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]

So, we have:

[tex]^7P_3 = \frac{7!}{(7-3)!}[/tex]

[tex]^7P_3 = \frac{7!}{4!}[/tex]

Solve each factorial

[tex]^7P_3 = \frac{7*6*5*4!}{4!}[/tex]

Answer:

B)  x = 7,  y = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

you can find the value of 'y' first by connecting the bases with another altitute measuring 4 units

you now have an isosceles triangle where each leg is 4 which makes the hypotenuse equal to 4[tex]\sqrt{2}[/tex]

to find 'x', it is the sum of 3 and 4

5

Step-by-step explanation:

add the fractions. you have to find the common denominator, 100/150+30/150+15/150= 145 so 5

1/30 of 150=5

The caramel apples that are covered with sprinkles are 5.

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Olivia has 150 caramel apples.

Each caramel apple is covered with one topping.

• 2/3 of the caramel apples are covered with peanuts.

• 1/5 are covered with chocolate chips.

• 1/10 are covered with coconuts.

The rest are covered with sprinkles.

Let 'n' be the number of caramel apples are covered with sprinkles.

Thus,we can write

(2/3)*150 + (1/5)*150 + (1/10)*150 + n = 150

100 + 30 + 15 + n = 150

145 + n = 150

⇒ n = 150 - 145

⇒ n = 5

Thus, the caramel apples that are covered with sprinkles are 5.

Answer:

  B) 124.96 ounces

Step-by-step explanation:

To find ounces, multiply the number of grams by the number of ounces in each gram.

  3550 × 0.0352 = 124.96 . . . ounces

Answer:

12.5%

Step-by-step explanation:

change/original amount * 100= percentage change

Answer:

The t distribution is used, because we have the standard deviation for the sample.

Step-by-step explanation:

When to use the z or the t distribution?

When we have the standard deviation for the population, we use the z distribution.

When we have the standard deviation for the sample, we use the t distribution.

In this question:

We have the standard deviation for the sample, which means that the t distribution is used.
