Answer:

54.74 ounces of tomatoes mark need.

Step-by-step explanation:

Given : Mark has three 4\frac{1}{2} oz cans and five 8\frac{1}{4} oz cans.

To find : How many ounces of tomatoes does Mark need?​

Solution :

Mark has three 4\frac{1}{2} oz cans.

i.e. 3\times 4\frac{1}{2}=3\times \frac{9}{2}=\frac{27}{2}

Mark has five 8\frac{1}{4} oz cans.

i.e. 5\times 8\frac{1}{4}=5\times \frac{33}{4}=\frac{165}{4}

Total ounces of tomatoes does Mark need is

T=\frac{27}{2}+\frac{165}{4}

T=\frac{54+165}{4}

T=\frac{219}{4}

T=54.75

Therefore, 54.74 ounces of tomatoes mark need.

Answer:

33.14\°

Step-by-step explanation:

Let

Y ----> field of vision that Yash's camera would need

we know that

Applying the law of sines

\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}

Solve for sin(Y)

sin(Y)=\frac{sin(41\°)}{30}(25)

Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]

Y=33.14\°

Betty saves 3 times as much as Ann. Charles save 390 less than Ann.. If Betty saves save 1330 more than Charles. how much does C
Igoryamba

Answer:

80

Step-by-step explanation:

We let x be Ann's savings.

Betty saves 3 times as much as Ann.

This implies that Betty's savings in terms of x

= 3x

Charles save 390 less than Ann.

This implies Charles savings

= x - 390

Betty saves 1330 more than Charles.

This implies that when we deduct Charles savings from Betty's we have to get 1330.

Mathematical equation for the problem:

3x - (x - 390) = 1330

Expand :

\implies 3x - x  + 390= 1330

\implies 2x + 390= 1330

Subtract 390 from both sides.

\implies 2x + 390 - 390= 1330 - 390

\implies 2x=940

Divide through by 2

\implies \frac{2x}{2} = \frac{940}{2}

\implies x=470

Hence Charles saving is

x - 390 = 470 - 390 = 80

Peanut allergies among children. About 2% of children in the United States are allergic to peanuts. Choose three children at ran
Step2247 [10]

Answer:

P(X=2|X≥1) = 0.0199973.

Step-by-step explanation:

The chance that each of the three children is allergic to peanuts is independent. Each with a chance of 2% = 0.02.

X follows a binomial distribution with

  • 3 trials, and
  • a chance of "success" of 2% = 0.02.

P(X = 2|X\ge 1) = \dfrac{P(X = 2 \cap X\ge 1)}{P(X\ge 1)}.

The event X \ge 1 includes

  • X = 1
  • {\bf X = 2}, and
  • X = 3.

In other words, X = 2 implies that X\ge 1.

P(X = 2 \cap X\ge 1) = P(X = 2) = \left(\begin{array}{c}3\\2\end{array}\right ) \times 0.02^{2} \times (1-0.02) = 0.001176.

P(X\ge 1) = 1 - P(X< 1) \\\phantom{P(X\ge 1)}= 1 - P(X = 0) \\\phantom{P(X\ge 1)}= 1 -\left(\begin{array}{c}3\\0\end{array}\right ) \times (1-0.02)^{3} \\\phantom{P(X\ge 1)}= 0.058808.

P(X = 2|X\ge 1) = \dfrac{P(X = 2 \cap X\ge 1)}{P(X\ge 1)} = \dfrac{0.001176}{0.058808} = 0.0199973.

natima [27]
First, find out how many pounds in a ton. 2000 pounds are in one ton. It is 70 cents for 1 pounds, multiply that by 2000 to see how much it costs for a ton. It would get you $1,400. Next, multiply 1,400 by 5 to see how much it is for 5 tons. It cost approximately 7,000 dollars.
