Step-by-step explanation:

x(x+10)=0===> x=0, –10

x²–3x–4x+12===> x²–7x+12=0

(x–3)(x‐4)=0====> x=3, 4

Jordan is cutting a 2 \text{ m}2 m2, start text, space, m, end text by 1\dfrac14\text{ m}1 4 1 m1, start fraction, 1, divided

sineoko [7]

Answer:

The area of each of the pieces is $\frac{5}{4} \ m.$

Step-by-step explanation:

The question is incomplete, so below is the complete question:

Jordan is cutting 2 meters by 1 \frac{1}{4} m piece of rectangular paper into 2 pieces along its diagonal.What is the area of each of the pieces?

Now, to get the area of each piece of paper.

So, the dimensions of piece of rectangular paper is 2 meters by $1\frac{1}{4}\ m.$

Now, to get the area of rectangular piece of paper:

$2\times 1\frac{1}{4}$

$=2\times \frac{5}{4}$

$=\frac{10}{4}\ m.$

The area of rectangular piece of paper = $\frac{10}{4} \ m.$

As, Jordan is cutting the piece of rectangular paper into 2 pieces along its diagonal.

Thus, the area of both the piece of paper are equal.

Now, to get the area of each piece of paper we divide the area of rectangular piece of paper by 2.

$\frac{10}{4} \div 2$

$=\frac{10}{4} \times \frac{1}{2}$

$=\frac{10}{8}$

On simplifying it:

$=\frac{5}{4}\ m.$

Therefore, the area of each of the pieces is $\frac{5}{4} \ m.$

Tutoring Services: The Community College Survey of Student Engagement reports that 46% of the students surveyed rarely or never

gulaghasi [49]

Answer: Mean = 0.40 and standard error = 0.0219 of the sampling distribution of sample proportions.

Step-by-step explanation:

Given : The proportion of community college students never use tutoring services available at their college: p= 0.40

Mean of the sampling distribution of sample proportions = p = 0.40

Since sample size : n= 500

Standard error = $\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.40(1-0.40)}{500}}$

$=\sqrt{\dfrac{0.24}{500}}$

$=\sqrt{0.00048}=0.0219$

Hence, Mean = 0.40 and standard error = 0.0219 of the sampling distribution of sample proportions.
