Answer:

[tex]-7 \times - 7 \times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7[/tex]

Step-by-step explanation:

Remember in order to find the answer of exponents you must multiply the whole number as many times as the exponent in this case..

[tex]7^{-12}[/tex]

[tex]7^{-12} = -7 \times - 7 \times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7\times-7[/tex]

If you want to solve remember that a negative times a negative will be a positive so the outcome would be a positive number.

Hope this helps.

pick 10 x 10 it is the easy one

Step-by-step explanation:

Answer:

Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

Step-by-step explanation:

The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.

Given

Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile

Distance of second walk = 5/7

In order to find how much he walked altogether, we have to find the sum of both fractions.

[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]

Hence,

Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

Step-by-step explanation:

Answer:

The answer is −2x+y=−4 or 2x−y=4 . Standard form is Ax+Ay=C

Step-by-step explanation:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

x 3 and 5 product of means product of extreme 3 and 4 is product of means 5 and 8 is the product of extreme x and your answer is coming follow the Rishabh

The probability of less than 4 students asking for tomato sauce along with their meal would be:

0.738

Given that,

Mean of the students asking for tomato sauce = 3/5

No. of random samples collected = 8 students

Given that,

Less than 4 = 0, 1, 2, 3

Let x be the number of students who ask for tomato sauce with their meal.

So,

[tex]P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)[/tex]

P(x = o) = [tex]C^{0} _{8} ( 1 - 3/5)^8 = 0.0007[/tex]

P(x = 1) = [tex]C^{1} _{8} ( 3/5) (1 - 3/5)^7 = 0.0079[/tex]

P(x = 2) = [tex]C^{2} _{8} (3/5)^2 ( 1 - 3/5)^6 = 0.0413[/tex]

P(x = 3) = [tex]C^{3} _{8} (3/5)^2 ( 1 - 3/5)^5 = 0.1239[/tex]

Using binomial distribution,

[tex]P(x< 4) = 0.0007 + 0.0079 + 0.0413 + 0.1239[/tex]

[tex]= 0.738[/tex]

Thus, 0.738 is the correct answer.

Answer: still air is 150mph. The wind speed is 30mph.

Step-by-step explanation:

X=speed of the plane, Y=speed of the wind.

360/2hours=180

360/3hours=120

2x=180+120

2x=300

X=150

The airplane in still air is 150mph

Add together

X+y=180

150+y=180

Y=180-150

Y=30mph

The wind speed is 30mph

Answer:

5 buses

Step-by-step explanation:

you need to divide the number of students (38) by the number of students a mini bus can carry.

38 : 8 = 4.75

since they want to know how many buses will be needed to transport all students, you round 4.75 to 5

32x+4=642x−1

Step-by-step explanation:

Resolver el exponente.

32x+4=642x−1

log(32x+4)=log(642x−1)(Sacar el logaritmo de ambos lados.)

(x+4)*(log(32))=(2x−1)*(log(64))

x+4=(

log(64)

log(32)

)*(2x−1)

x+4=1.2*(2x−1)

x+4=2.4x−1.2(Simplificar ambos lados de la ecuación)

x+4−2.4x=2.4x−1.2−2.4x(Restar 2.4x a ambos lados)

−1.4x+4=−1.2

−1.4x+4−4=−1.2−4(Restar 4 a ambos lados)

−1.4x=−5.2

−1.4x

−1.4

=

−5.2

−1.4
