Answer:

The appropriate null hypothesis is H_0: \mu = 1250

The appropriate alternate hypothesis is H_a: \mu < 1250

Step-by-step explanation:

At the null hypothesis, we test if the mean area is the advertised area of 1250 square feet, that is:

H_0: \mu = 1250

A tenant group thinks that the apartments are smaller than advertised.

Smaller, thus, at the alternate hypothesis, we test if the mean area is less than the advertised area of 1250 square feet, that is:

H_a: \mu < 1250

iragen [17]

Answer: 4 seeds will left over.

Step-by-step explanation:

Total sunflower seeds = 1354

Number of people shared sunflower  seeds equally = 6

By division operation,

Number of seeds each people will get = (Total sunflower  seeds) ÷ (Number of people shared seeds equally)

= (1354) \div (6)

=225\dfrac{4}{6}

Hence, each people will get 256 sunflower seeds and 4 seeds will left.

Solve 5√3 as the square root of a single number​
Andreyy89

Answer:

/75

Step-by-step explanation:

As I couldn't take the radical symbol I used this - "/".

5 /3

If 5 has to come in the radical sign it has to be squared

So, /25 × /3

/25×3

/75

Solve: 2x+3y=1<br> y=-2x+11
Sauron [17]

Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5
