Answer:

(A) We failed to reject the null hypothesis

Step-by-step explanation:

Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:

Here p value is 0.34

This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.

Whenever p > alpha, we fail to reject null hypothesis

A)  We failed to reject the null hypothesis

This would be the correct option

i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.

Answer:

x=12, y=60

Step-by-step explanation:

Because the oppsite lines are parallel (you can tell because of the arrows) the opposite lines are the same length and the opposite angles are the same size.

This means y = 60 and x + 3 = 15 so x = 12

What is the solution to the given system of equations?<br><br> y=4x-3<br><br> y=-x-13
Paraphin [41]
4x - 3 = -x - 13
4x + x = -13 + 3
5x = -10
x = -10/5
x = -2

y = 4x - 3
y = 4(-2) - 3
y = -8 - 3
y = -11

solution is (-2,-11)

Which equation represents a line that passes through (2,-1/2) and has a slope of 3 ?
Anna11 [10]

Answer:

C. y + \frac{1}{2} = 3(x - 2)

Step-by-step explanation:

Given

Point:  (2,\frac{-1}{2})

Slope: 3

Required

Equation of line

Let m represents the slope of the line;

m is calculated as thus

m = \frac{y - y_1}{x - x_1}

where (x_1,y_1) = (2,\frac{-1}{2})

So; x_1 = 2; y_1 = \frac{-1}{2}

m = 3

By substituting the right values in the formula above;

m = \frac{y - y_1}{x - x_1} becomes

3 = \frac{y - \frac{-1}{2}}{x - 2}

Multiply both sides by (x - 2)

3 *(x - 2) = \frac{y - \frac{-1}{2}}{x - 2} *(x - 2)

3 *(x - 2) = (y - \frac{-1}{2})

3 *(x - 2) = (y + \frac{1}{2})

3(x - 2) = (y + \frac{1}{2})

3(x - 2) = y + \frac{1}{2}

Reorder

y + \frac{1}{2} = 3(x - 2)

Hence, the equation that represents the line is y + \frac{1}{2} = 3(x - 2)

Please help solve quick
RoseWind [281]

Answer:

see below

Step-by-step explanation:

3x^2 + 17x +10 =0

(3x+   ) ( x+   ) =0

We need to factor 10  = 2*5  or 1*10

They are positive since we have all positive terms

3*5 = 15+2 = 17

The 5 needs to multiply the 3 so it goes on the outside

(3x+   ) ( x+  5 ) =0

That leaves the 2 on the inside

(3x+ 2  ) ( x+ 5  ) =0

Using the zero product property

3x+2 =0     x+5=0

3x = -2          x=-5

x = -2/3          x = -5
