According to the line of best fit, the value of time when the temperature reach 100°c, the boiling point of water is 5.

Linear regression is a type of regression which is used to model the statement in which the growth or decay initially with constant rate, and then slow down with respect to time.

The table shows the temperature of an amount of water set on a stove to boil, recorded every half minute. a 2-row table with 10 columns.

The sum of time is 22.5 and the sum of temperature value is 880.5. In this table,

The regression equation for this data can be given as,

[tex]\hat y=4.53939 X+77.83636[/tex]

Put the value of temperature (y) 100 in this equation.

[tex]100=4.53939 X+77.83636\\X=\dfrac{100-77.83636}{4.53939}\\X\approx 5[/tex]

Hence, according to the line of best fit, the value of time when the temperature reach 100°c, the boiling point of water is 5.

The null hypothesis for the test regarding the blood type is that they distribution of blood types among art major is the same as the US distribution.

It should be noted that null hypothesis simply suggests that there is no statistical relationship.

Here, the null hypothesis for the test regarding the blood type is that the distribution of blood types among art major is the same as the US distribution and the alternative hypothesis is that the distribution of blood types among art major is different from the US distribution.

The conditions for this test have been met as all expected frequencies are greater than 5.

Since the test statistic is 9.63 and the p-value is 0.022, one can reject the null hypothesis. Therefore, it'll be concluded that the distribution of blood types among arts majors and minors is different from the U.S distribution.

[tex](5i)^2\\\\=25\cdot i^2\\\\=25(-1)\\\\=-25[/tex]

(5i)² can be written in integer form as as -25.

The numbers which can be expressed in the form of a + ib, where both 'a' and 'b' are real numbers and 'i' an imaginary number is called complex numbers.

So a complex number has a real part and an imaginary part.

The imaginary number 'i' is called iota and value of i is √-1.

We know the value of i.

i = √-1

i² = -1

(5i)² only has an imaginary part.

∴ (5i)² = 5² i²

          = 25 × -1

          = -25

Hence we can write (5i)² as -25 in the integer form.

The value of c that makes the given trinomial a perfect square is 9.

The given expression is:

[tex]x^{2} +6x+c[/tex]

A polynomial is called a perfect square trinomial if it can be written in terms of the square of another polynomial.

Let us write the given expression in (a+b)² form

[tex]x^{2} +6x+c[/tex]

[tex]x^{2} +2*3*x+c[/tex].....(1)

We know [tex](a+b)^2=a^{2} +2ab+b^{2}[/tex]......(2)

To make (1) like  we need to put c=9

[tex]x^{2} +2*3*x+9[/tex]

[tex]x^{2} +2*3*x+3^2[/tex]

[tex](x+3)^2[/tex]

Answer:

b

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

the discriminant b² - 4ac informs us about the nature of the roots

• If b² - 4ac > 0 then roots are real and irrational

• If b² - 4ac > 0 abd a perfect square then roots are real and rational

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 the roots are complex

4x² + 6x - 7 = 0 ← is in standard form

with a = 4, b = 6, c = - 7 , then

b² - 4ac = 6² - (4 × 4 × - 7) = 36 - (- 112) = 36 + 112 = 148

since b² - 4ac > 0 then roots are real and irrational

Answer: 6/7

Step-by-step explanation:

The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

The volume of the larger sphere = 64π cm³

let us take the radius of the larger sphere r

So, 4/3*π*r³ =64π

r³=48

r=2∛6

The surface area of a sphere with radius r is 4πr².

So, the surface area of the larger sphere = 4π(2∛6)²

The surface area of the larger sphere = 16π∛36

Hence, The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

The dot plot shows the frequency or length of the tadpoles

The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

From the dot plot, we have the following parameters:

So, the total length is:

Total = 3 * 1/8 + 2 * 1/4

Evaluate the product

Total = 3/8 + 1/2

Rewrite as;

Total = 3/8 + 4/8

Evaluate the sum

Total = 7/8
